Audio drivers work properly but no sound.

teapee28 · 06-15-2008, 02:01 PM

I have a hp pavilion a730n. The audio driver that I have is a realtek. For some reason after an automatic windows update the sound stopped working. The only time speakers work is when I do a speaker test. There seems to be no conflicts and all devices are said to be working properly. I tried uninstalling and reinstalling the drivers as well as roll it back and did a system restore but with no success. Can you help me figure out what I can do to fix this problem? Will a new sound card suffice?

Hi

Open Control panel >> Add or remove programs >> remove the Realtek audio driver/software.
Then install this driver: ftp://218.210.127.132/pc/audio/WDM_R195.exe
Restart the computer.

Also - have a look at this: Sound problems? Try these things first.

Hello and thank you for helping me. I tried uninstalling the audio driver program from my computer but it said there was an error with setup.exe and it wouldn't let me uninstall. So I just installed the WDM_R195 and restarted my computer. After restart there was a warning that said that no windows logo was detected or something like that and recommended me to stop installation, but I proceeded anyway. After all this my sound still does not work.

Look in device manager (To open Device manager: Click Start >> Run >> Type devmgmt.msc and click OK).
Click the View menu >> show hidden devices.
Any red or yellow "marks" in device manager?

Try going through the steps in the thread I posted.

teapee28 · 06-16-2008, 12:54 PM

There are no red or yellow marks and I have done almost everything on the link you gave to me with no success.

Play a sound file in media player and see if the graph moves.
If it does, the sound output must be muted "somewhere".

Also - make sure Realtek is the default playback device (control panel >> Sounds and audio settings). Sometimes a webcam, TV card etc wants to be default and kicks the sound card/chip out.

teapee28 · 06-17-2008, 04:24 AM

Realtek is default and the sound is not muted. Windows Media tells me that the audio driver can not be detected.

Make sure the audio has been started by Windows:

Click Start > Run > type services.msc - then click OK.
In the new window - Scroll down to "Windows Audio", right-click on it and select Properties.
Another new window - set the startup type to Automatic, click Apply and then click Start.

Run the sound and music tests in DXdiag (click Start >> Run. Type dxdiag, then click OK).

teapee28 · 06-17-2008, 11:08 AM

the directx diagnostic tool did not detect any sound driver.

Start Windows in safe mode (tap F8 when the computer starts) >>
open Control panel and remove all Realtek software.
Then reinstall the driver I posted earlier >> restart Windows in normal mode.

teapee28 · 06-18-2008, 01:31 PM

Unfortunately, it still doesn't work.

teapee28 · 06-20-2008, 12:04 PM

Can I just get a new sound card or install a new audio driver somehow to fix the problem since nothing I do seems to work?

**Deleted090308** · 06-20-2008, 07:02 PM

I don't think so. The error seems to be located in Windows itself.
Are you having other problems with the PC?
Any signs of malware (virus/spyware)?

teapee28 · 06-21-2008, 12:28 AM

I did a virus and spyware scan right after this problem occurred because it was an unusual problem but it found nothing. And I don't seem to have any other problems with my computer.

**Deleted090308** · 06-21-2008, 01:04 AM

Did you check "Windows Audio" in Services?

Try creating another Windows account and see if the sound works when you log on that account.

teapee28 · 06-21-2008, 11:25 AM

I tried another windows account but the sound didn't work. After the problem occurred, I had another conflict with some Windows audio driver and from what I read on the trouble shoot it recommended me to delete it. Could this be the problem?

**Deleted090308** · 06-21-2008, 12:02 PM

What driver caused the conflict?
Don't delete it - see if you can disable the device/driver in device manager.

teapee28 · 06-21-2008, 01:02 PM

I forgot the exact name of it. It was named something like windows media audio driver. It was already disabled but the conflict sign was still there so i deleted it. Should I do a system restore to a time when i had the driver and work with fixing that?

**Deleted090308** · 06-21-2008, 01:12 PM

No - Please download and run StartUpList.
In the program >> click File, Save As.
Save the report as a txt file and attach it to your post.

How to post an attachment.

It may be possible to see what's wrong in that report.

Here is my startuplist.
