There is no output device (Realtek HD Audio)

Q: There is no output device (Realtek HD Audio)

Hello,

first I already wanna thank everybody who replies to this and try to help me. Yesterday morning I tried to download a sound driver that would make the Stereo Mix option available. It was not from the original website of Realtek or HP. It was from here: http://driveragent.com/c/archive/196a161c/Realtek-High-Definition-audio#summary. After I finished the installation and restarted my PC there was a red cross next to the sound icon and when I tried to open volumemixer it said 'No audio output device installed'. I tried to uninstall it with system restore. Than I also tried to install the latest sound drivers from the Realtek and HP site but both didn't work. Also I saw on another topic that maybe some services were stopped but that wasn't. Now I really don't know what to do. Hope someone can help me.

Hello all I have Win 7 32-bit on my gateway mx6437 and am having the same problem that several people are having here - no sound. I downloaded the latest Realtek AC '97 drivers from the Realtek website. I checked to see if this card was compatible with Win 7 32-bit from the compatability website. Right now the drivers are "installed" but Win 7 says its unsuccessfully installed.

I have an AMD Turion 64 card. Please help I've been researching this issue for the past 2 weeks without success.

Hello.

Im having the dreadful "No Audio Output Device is Installed" problem on my realtek audio.

It worked some months ago, but im in no position to do a roll back. Im sure the hardware is just fine, it works with Ubuntu.

The computer is a Dell Vostro 430.
My OS is win7 64bit.

I tried the newest Realtek driver suite, the recommended dell-drivers and some basic windows-drivers. Nothing makes the "No Audio Output Device is Installed" go away.

Any help is welcome.
Ive attached my sound-related reg. I believe my realtek device is 0001.

A:Realtek Audio: No Audio Output Device is Installed

The Dell driver is required, non Dell drivers will either not work or not work correctly.

First thing, is the Integrated Audio enabled in the BIOS? (F2 at boot up to enter Setup).

Second, on Dell's (and many others) if the motherboard chipset drivers were not installed, the sound device will not work. In this model there are Intel motherboard chipset drivers. Try installing them and then the Dell sound driver. Dell Drivers

A:Asus Laptop/RealTek "No Audio Output Device is Installed"

From your description, I'm going to suggest what I try to avoid at all costs. Do a complete reinstall. I know its a hassle but sometimes its what is needed.

Backup your user data to some external media (USB flash drive, CD/DVD media, etc) first as the reinstall will wipe it all out. Then do the reinstall, using the recovery mode that I assume ASUS has (most PC vendors have a recovery partition on the hard drive that will allow restoring to the original factory condition).

Hi to all.

On my Dell OptiPlex 755 E6550 2.33, I've had intermittent issues with the headphone socket suddenly stopping working for quite some time,sometimes problem is auto detected and fixed, sometimes I download a driver or three to resolve. This time nothing is helping no matter what drivers I've tried. Have Win 7 Ultimate installed with just on-board sound. No sound or audio shows up in device manager? Are 755's fickle with on-board sound or just too many sound drivers installed? Any ideas please.

A:Realtek ALC889 audio, audio fine on S/PDIF, nothing from rear output

I found out after a while. In the popup dialog when a cable is plugged in, I had selected "Rear speaker out" mistakenly thinking it was talking about the rear output, not the rear speakers in a 5.1 speaker setting. Changing to "Front speaker out" solved the problem.

A:Realtek HD Audio only shows one audio output at a time

Hello audiobreak,

Try going into the Realtek HD Audio Manager (Control Panel > Hardware and Sound > Realtek HD Audio Manager), then look for a setting called 'Make front and rear output devices playback two different audio streams simultaneously'. I cannot remember where this is located (The Realtek HD Audio Manager has different skins depending on the motherboard vendor), but for an ASUS Motherboard, I believe you click the Cog Icon in the top left and the option should be in there. I don't know if this will create a separate Playback Device for the Front Panel in Window's Playback Devices, but it will at least allow you to hear audio from both your speakers and headphones at the same time.

Hope this helps.

Which 1 of these is better sound card and will it work on my hp p6310f. ASUS Xonar DG 5.1 Channels 24-bit 96KHz PCI Interface Sound Card - Newegg.com

Well first; before you go and spend money on another sound card; try this: go into the device manager in control panel; and completely uninstall the device. Then reboot and let windows re-detect it and reinstall the drivers for it; then check to see if there are any updates for those drivers and install them. Try this out and see if it helps ya any.

I have a little problem, with my notebook.
I've installed Win 7, and it's working fine, except that there is an optical jack output on my notebook, but I can't use it, because the I can't see it on the Realtek HD audio manager.
With XP, it worked fine. And when I plug in the optical cable, the software defines it as a headphone....
The audio hardware is Realtek HD Audio (ALC883), and it an msi s262x notebook (with Realtek R2.16 vista driver).

If you have some good ideas please tell me.

Good evening, folks!

I've recently bought an ASUS notebook, model K45a. After a few days, I upgraded from Windows 7 to Windows 8, but I didn't like it, so I formatted it and reinstalled Windows 7 64 bits.

I've installed all the preferred drivers from the asus website, but there is no digital output! I got the newest Realtek Audio driver, and no digital output option available.

I've been to Control Panel > Hardware & Sound > Sound > Manage sound devices and right-clicked to select "show disabled devices" and "show disconnected devices" (sorry if it's not 100% accurate, I'm using a portuguese Windows version and trying to translate it accordingly) and nothing.

All I get is the speakers, no digital option, which means no 5.1 signal through both spdif or hdmi to my home theater. When I open Realtek HD Manager, it only displays the analog jacks.

Any thoughts on this?

Thank you!

A:Realtek Audio Jack Output Assignment Troubleshooting

1. I see you have the "High Definition Audio" as the device type. That suggests that you do not have the RealTek sound driver installed. Instead just the basic function Microsoft/Windows sound driver.

I have RealTek and I have a RealTek HD Audio Manager that will allow SOME (not all) jack assignment changes.

You can only have one default audio playback device and if I understand you correctly, you can't have different devices for different outputs. You can have "Stereo" (2 channel) or 2.1 speaker system that is connected to the Green speaker jack. OR you could have a 5.1 speaker system with the the THREE connections to the PC. But, you can't have one jack for one device or speaker system and another for a different speaker system.

I checked my Drivers and my High Definition Sound and 2 Base System Device drivers have Yellow Question Marks by them. I tried to update the drivers manually but it says Windows Cannot Find Support for your Base System Device and it says my High Definition Audio is already up to date. I have also tried uninstalling the drivers and rebooting Windows to let the system automatically search and update the drivers. This too has failed. I do not have my Windows 7 disc available at the moment to be able to do a clean install.

I have gone through the whole update drivers circus to no avail, my laptop can't detect that it has speakers built in so it doesn't bother finding a driver for them.

This is where I am at:
- Intel Display Audio is the only driver installed for sound
- This means that sound works when the laptop is plugged into an HDMI
- When HDMI is not plugged in, the computer cannot find the built in speakers.
- I have Linux on this system and audio does not work there as well

I would call this a broken chipset, but the fact that the computer still processes audio with the HDMI cable attached is confusing me. Also, the 'audio board' for this laptop has 2 usb ports attached to it, and those both work fine.

Any help would be appreciated

A:Audio Playback (Default Device Realtek) Knocks Out SRS Audio Sandbox

If it worked at one time and now does not, have you tried making it the default audio playback device rather than the RealTek? Or have you tried reinstalling it?

I have no audio at all since the last update from windows 10 in early April.  I am showing a No audio output device installed on the audio icon on my computer.  When I go to device manager it shows that I have no sound components and an error code 39.  This is starting to really frustrate me.  I have tried everything and nothing works.  Be it said I am not an IT person and am limited in my knowledge of computers, but still I am pretty sure it can be a simple fix.

Hi,
I just realized that stereo output is inverted (L&R are swapped) on my Realtek front panel headphones connector and on my M-Audio Firewire card. Output is OK on Realtek rear main/front speakers connector.
Any ideas on how to fix this?
Thanks,
J

A:Stereo Audio Output Inverted on Realtek Front Panel and Firewire Card

The front panel Headphone switch could just be a wiring error in the front panel, since it is correct at the rear panel. Or the cable that connects the front panel to the motherboard has a wiring error (assuming the connector is properly connected). Many cases have two audio connectors for the front panel, HD Audio and AC97 audio. The HD Audio is the preferred, if you are not using that, connect it and see if that helps. If you have HD Audio connected, and you have AC97, use that.

The MAudio device is a separate issue. I have a Sonar X2 recording studio and have an MAudio Fastrack Ultra 8R interface unit (and a Roland Octa-Capture). I used to have a firewire unit, a Focusrite Saffire Pro 40 and any channel swapping was done in the DAW program (e.g. Sonar).

A:NO audio output device

After looking at you specs I really need to know what CPU you are running, whether you are using an internal sound card (on mother board), or PCI card, and if so the manufacture, and the age of the card. The sound card may not be supported either. Also even if you are running a 32 bit version of Win 7 512 of ram is just a might to low. You system would run a lot smoother with 2 gigs.

I have an HP Pavillion2845 Laptop.

A:No Audio Output Device

Give this site a try:

HP Business Support Center

It is not tech support provided by HP. It is voluntary support provided by HP business users. But there are some savvy people on there. As an example, I had HP PCs with Intel chips that kept locking up due to overheating. The fans never bumped up to higher speed when the CPU got hot. Turns out there was an "Easter Egg" or undocumented hotkey that opened a page in the BIOS setup they don't tell you about in the manual. On that page I could set the fan speeds and trigger temperatures.

I found out about that setup page in the HP business forum.

I remove and reinstall the drivers and I still have no sound. This one's got me stuck. I've tried having windows download the drivers automatically, downloading the drivers from intel directly and anything else I could think of. Sometimes I was able to get the red X to go away and it looked like it was working. However there was still no sound. I've even tested the speakers with another source and they work.

I've attached the full system specs in a text file.

Any help would be greatly appreciated.

A:No Audio Output device is installed

I had the same problem, and it seems like many others are also, after the Vista SP1 update. Has something to do with audio codecs getting messed. I'm using a Realtek AC97 audio, not a high def like you, however I suspect it may be the same problem. I tried reinstalling drivers too with no luck. However, after reading around the web, this 3 step fix worked for me, and now I'm back to normal.
1. I downloaded and ran the k-lite mega codec found here.

http://www.free-codecs.com/K_Lite_Me...k_download.htm

2. In the control panel/sounds/select speakers/properties/advanced tab I hit the restore defaults button.
3. Changed back my default programs back to the one I use, windows media player, since k-lite changed defaults, and was good to go.

You might want to simply try step 2 by itself first, however if that button is greyed out, then you are already at defaults, and I'm not sure if the rest would help. I hope this gets you in the right direction, good luck.

See if re-installing the current sound driver will help. See below article (mainly method 5)

A:No Audio Output Device is Installed

The green check should mean that the device is still working correctly.
By this I mean that the driver for the device is functioning as expected.

Therefore, it must be a setting within the audio software for your machine,
in this case being the Conexant Smart Audio, which also says that it is ready.

Check the driver for the device anyway by right clicking the speaker properties
button in the sound window and under the general tab->controller information click properties again. Then click on the levels tab in the speaker properties box and check that the audio output level is 100 and there is no red mark near the small blue speaker as there is with microphone and line in as shown in the image I have provided.

Last of all click on the advanced tab in speaker properties and if yours is similar to this image then uncheck the boxes under exclusive mode and then click on restore defaults. I have a very similar model to your machine and by clicking this button it will restore the sample rate and bit depth to be used when running in shared mode. Mine says 24bit 48000Hz (studio quality).

Sometimes these changes can occur due to the use of a particular program or programs being used at the same time or in conjunction with each other. Maybe
it has just happened by accident (went to sleep on plane and head hit keyboard!!!)

Hope this helps- let us know how you go

Cheers
Edit: Make sure in speakers properties box that under the general tab the device usage
is set at "Use this Device (enable)"

This seems to be a common issue, and I've looked and looked but nothing has solved my problem.

I'm using a Toshiba Satellite U305-S7467 running Windows Vista Home Premium.

There is a red x over the speaker icon, when I hover over the icon it says "No Audio Output Device is installed."

I've tried uninstalling and reinstalling drivers in and out of safe mode, using the windows updates that are supposed to fix the issue, countless restarts, but nothing has helped. In the device manager the driver isn't in the sound category, but there's a high definition audio device under the system devices category. I've uninstalled and reinstalled in plenty of times. Still nothing. I don't know what to do anymore.

Does anybody have anything to suggest? I really need my sound back!

Hi, I'm running windows 10 on a W540 with Realtek High Definition Audio and Dolby Digital Plus. Rececenlty I noticed the Dolby Digital Plus utility was not working.  Based on guides from lenovo I uninstalled and reinstalled my audio drivers. Now Dolby Digital Plus is running but I have no audio. The audio icon says no audio output device is installed. Realtek does show up in device manager. Windows troubleshooting says audio services not responding. Restarting them does not seem to fix anything. The only other suggestion I've seen is reinstalling windows 10.

A:No audio output device is installed

Is this a New Acer, or have you had it for a while.
Many Acer's are not capable of being over-driven. They will become hot and sometimes fail when over-driven at high volume
If it is still under warranty, get it replaced or repaired, and hope you have not voided the warranty by doing your own internal examinations.
If out of warranty, it is possible you may need to replace the system board.
Now might be the time to have an experienced Acer tech take a gander at the innards.

Hi I Device Output No Installed Is Audio ve been having an on-off problem with my Vista -bit computer No Audio Output Device Is Installed for about a year now It happened after I changed the language system locale on my computer from English UK to English US changing it back to English UK didn t solve the issue The problem is sometimes the audio won t work and I get the No Audio Output Device Is Installed message over my speaker icon I haven t got a clue why the problem isn t constant sometimes when I switch on the computer the sound is fine and other times it isn t working There have been loads periods where the sound works fine for months so I assume the problem has fixed itself but then the audio doesn t work again one day The problem seems to have come back again now and has been happening on-off for about a month now I tried reinstalling SoundMAX when the audio was working yesterday it never allowed me to install it when the audio was off and managed to get it installed I thought this would solve the issue but today I turned on the computer and the sound was dead again accompanied by a message that said something along the lines of Your audio configuration has changed you must reinstall SoundMAX I tried doing that but it says the files don t support my computer I should also note that I ve tried most of the solutions on google like going into device manger and enabling the sound drive but the Sound Video and Game Controllers tab doesn t even exist in DM when the audio is dead It s all very mysterious as to why my sound is doing this I ve tried scanning my system for malware amp viruses as well and removed all of the viruses it did fine didn t fix the audio I m at a loss at what to do here the only thing I can think of is that the audio sound card is faulty I would add an attachment of speccy of my computer s specs but I don t currently have access to my PC on another comp at the moment However I ll attach a file later if it s needed Any help would be appreciated Edit In reply to Oddba alright will do My audio is currently working so I didn t see the point in posting a new message in this thread but as soon as the audio dies again I ll have a look in device manager nbsp

A:No Audio Output Device Is Installed

When the problem occurs, check Device Manager and see if the audio chipset is listed. If it's listed, it could simply be a driver issue. Try updating/reinstalling the audio drivers. If it's not listed, most likely it's a hardware fault (ie: faulty audio chipset). The language change is likely just a coincidence.

For HP computers & laptops, you must install the sound driver which is available from HP's website, not from Realtek's website. HP computer's use modified, custom-made drivers which are available only from HP:

Honestly, Looks like everything has been tried...Just double checking Have you formatted and install the OS back? as from what I see that is the only thing left out...If the Audio card still does not working than we have hardware issue which is a big surprise, Audio card failure is rare....Same goes for not able to write DVDs, you have to test it post format and reinstall...

As this just happened, use the System Restore function and restore the PC back to an available restore date when it worked OK.

The coprocessor is a separate issue and most likely not related to sound.

I decided to purchase a Lindy USB audio adapter to hopefully add sound again to the dv6615em.When the Lindy adapter arrived and I tried to install the device it would not install properly or failed.Thinking that was it, nothing will work, sound is gone forever I chose once again to format & reinstall the laptop using OS Vista (Home Premium) 32bit, but this time a version without the service packs included.I could not believe it when the installation completed and the sound icon did not have the dreaded X through it!After installing wireless network adapter I went onto install SP1 first and then use Windows update.As far as I was concerned the laptops sound device had 'had it'.  It seems by installing the same OS but without any service packs was the answer to my particular problem ?

Try control panel(large icons) and going into your sound, and manage or view sound devices. If there is nothing in your output(playback), then thats a problem. If there is, then select your speakers/headset/anything you use that generates audo that is connected to your computer that. If all else fails, try a new soundcard

Ouch, sound like the updates really messed up the system.

With the System Restore errors and both the RealTek and HDMI audio errors (and who knows what else), unfortunately it may mean a reinstall.

I had some problems and and the same System Restore problem. I had to use a Macrium hard drive backup and restore my PC from the hard drive backup.

When I turn on my computer I have a red X on the speaker and it states NO OUTPUT AUDIO DEVICES INSTALLED.
If I shutdown and reboot my computer I get my sound back. I am using the HDMI to my TV.
This started about 3 weeks ago.I've updated my drivers and that didn't work.

I have just done a clean install from xp to windows 7 64 bit, everything is working fine except i have no audio, in the right hand of the task bar i am getting no audio output device is detected. If i look on device manager there is a fault on the multimedia audio controller

The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver.

I have been looking for a driver for the last 3 days but none seem to work, if anyone could lend me there expertise that would be great as its driving me crazy(no pun intended)

A:No audio output device is detected

Hello there. You should give us your information about your's audio card. You can do that bu following:
Download and install Everest from here. Start it and go to Multimedia -> PCI/PnP Audio. In the right side you'll see Driver Description,and bellow that something like this.

Also I'll suggest you to update your system spec.

A:No Audio Output Device Is Installed?

hello

try this. right click your speaker icon (next to clock) choose: sounds

then choose the playback tab. is there a green check mark next to speakers ?

if not click speakers. click set default. click apply.

if yes try uninstalling your realtek high definition audio and reboot let windows reinstall.

good luck

All right I know this is a pretty common problem and it's probably been asked a lot but my case seems to be a bit different than anyone else's A while back I downloaded a registry Output No Audio Installed Device file to try to get sound in safe mode Stupid I know No Audio Output Device Installed Anyway it didn't work but ever since then my sound has not worked in normal mode either Earlier today I went to device manager and looked and saw there was no Sound Video Game Controllers installed Anyway I went and got the Realtek Driver for my Gateway GT and tried to install and I don't know what happened but it didn't seem No Audio Output Device Installed to work Then I attempted to install the Legacy driver and that worked but now it's saying quot the device cannot start Code quot I'm not really sure where to go from here If you want I can supply a link to the registry file that seemingly screwed it up and maybe we can work from there

perform a factory recovery after backing up all your files to another drive.
