APPLICATION ERROR

ARE you sure about uninstalling .Net Framework 3.5, as some large programs require it.

I have the same problem, recently decided to run every option in K-Lite Mega Codec Pack 5.5.0

I can adjust volume via Control Panel_Sounds & Audio Devices_Volume.

The Advanced feature fails - nothing happens.

Under Speaker Settings_Advanced, my Speaker setup was changed (not by me) to 5.1 output. from desktop stereo.

One option is "No Speakers".

Windows XP -SP3 using SoundMax drivers.

I had the exact same problem, and I had also run the K-lite "Codec Tweek Tool" at some point.  I would like to thank Feruken and ecyoung for finding the problem, and solution, respectively.

I would like to make an addendum to the final solution; for me the problem was solved as soon as i went to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

and changed the value of "aux" from "C:\Windows\System32\wdmaud.drv" to "wdmaud.drv".

This is kind of odd since they should both point to the same file... but i guess thats windows for you lol.

I did not have any need to do anything with .NET or delete any registry values; however, since i may be a little obsessive i removed the "C:\Windows\System32" prefex from all off the divers or codecs in that registry key for the sake of consistency, and to possibly preventing similar less obvious issues.

Anyway, I strongly suggest that you back up that registry key before making any changes.

Hope this helps.

and thanks for the help!

The Codec Tweak Tool option to "Fix broken sound" causes this problem.  It does two things.  (1) It sets HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32, 'aux' string value to "C:\Windows\System32\wdmaud.drv".  I think 'aux' should be set to "wdmaud.drv".  (2) It creates a new, I believe unnecessary, string value named 'wdmaud.drv' set to "C:\Windows\System32\wdmaud.drv".

I am not sure how to contact the author of Codec Tweak Tool.  Perhaps someone else will have better luck with that.

NOW HERE IS THE SOLUTION TO OUR PROBLEM! All Thanks Goes To ecyoung for pointing out registry changes done by "Codec Tweak Tool", and others who also noted about .NET Framework installations.

ALL YOU HAVE TO DO IS: First uninstall any .NET Framework versions ABOVE .NET Framework 3.0 by using "Add Remove Programs" under Control Panel. Now run 'Registry Editor' by clicking "Start" then selecting "Run" and type 'regedit'. In the left pane of Registry Editor expand " HKEY_LOCAL_MACHINE" then "SOFTWARE" then "Microsoft" then "Windows NT" and then "CurrentVersion". Highlight "Drivers32" you will find many entries on the right pane. Find "aux" string and delete it. Now try opening Volume Control and it should now open. Problem Solved!

Thanks goes to all people who kept posting on this post for so long time. My problem was not limited to "SNDVOL32.EXE" but also with some other programs. Although the sound was ok but i was getting "0xc0000005" error on 'SNDVOL32.EXE' and in some other programs. Thanks again to all of you!

Just that I might've found the cause of the SNDVOL32.exe Application error. It's strange though that it stopped other programs from running, too.

So you say that you've never used the Tweak tool and the problem with your sound came up. Wow, I don't know what it could be for you then. How long have you been using your current installation?
