No internet audio, registry problem

I have a Sony Vaio laptop that I’ve restored to the factory original XP Home Edition from the restore partition on the hard drive.  There is no audio working on the internet (IE6, IE8 & Google Chrome), for example on YouTube.  Audio still works fine when opening audio file on my computer’s hard drive, or CDs, or during bootup and shutdown.  

I have uninstalled and reinstalled Adobe Flash Player 10 with no improvement.  I have examined the registry and found that there is only one entry in HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Drivers32.  It is Name = ab(Default), Type = REG_SZ, Data = (value not set).  

I right click and select New > String Value and the default entry created is Type = ab(New Value #1), Type = REG_SZ, Data = (value not set).  Then I change the Type of the new entry to wavemapper, but I get the following error message, “The Registry Editor cannot rename New Value #1.  The specified value name already exists.  Type another name and try again.
Next I go to the top of the Registry Editor and I click on Edit and select Find…, and enter wavemapper in the Find what: field, with Look at Keys, Values, and Data all selected.  But it finds nothing.

It seems like the missing entry in the registry is the problem, but I can’t get it to accept my modifications.  What am I doing wrong?

How about this though....

1. go into the Advanced Audio properties and make sure that there is nothing muted.
2. Advanced IE Options, and make sure that under Multimedia, "Play sounds from webpages" is checked... Long shot on this one though.....

Thanks for your quick response John.  I tried the 1st method listed above, "reg query" and it returned the message "Error:  Access is denied".  I am doing this from a Computer Administrator account though.  What does this mean?

Corrupted permissions probably...

Right click "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32", and select Permissions. Hit the Advanced Button, and select the first checkbox on the first tab. It is probably not checked....

Also, check to mke sure the Administrators group is the owner of the key. If needed, go back to the Security Tab, and add your user id/Full Control, and then retest the query....

The 1st checkbox was already checked.  The Administrators group is and was the owner.  I did gave the user id Full Control and Read.  

But still it reports "Error:  Access is denied" from the query.  What next?

Is there a file called msacm32.drv in C:\windows\system32?

Have you checked the permission for C:\windows\system32?

Open the Global Storage Settings Panel:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html

Check the box labeled: "Allow third-party Flash content to store data on your computer."
To ensure the check sticks please click one of the tabs at the top of that box and then click back to the (Global Storage Settings Panel). The box should still be checked.
Once this is complete, close all browser windows and try playing a video

I honestly don't think you need to be editing registry entries for this...it really just sounds like its a driver or windows setting issue. Check the windows volume control (if the speaker icon isn't in taskbar, go to control panel -> sounds and audio devices -> Audio tab -> Volume on default sound playback device !!!make sure you go to windows settings, not the soundcard driver settings!!!). If it only shows the main volume option, go to Options -> Properties and check all controls on. It's likely that one is muted.

Another typical method is to uninstall the soundcard from device manager -> scan hardware changes. It should automatically reinstall and take care of the issue.

If you cannot do a simple reg query, the permissions seem to be hosed on that key....

Kinda wonder what else might be hosed.... Can you create a new user and see if you can verify the reg entry?

Jackieman - I do have msacm32.drv installed, but I'm sorry, I don't know how to check the permission on C:\WINDOWS\System32.  How do I do that?

Flubbster - The box is already checked, but I did go to another tab and then back again and it remained checked.

johnb6767 - I created a new acct, logged out of the other one, logged into the new one, ran the query there, but got the same message "Error:  Access is denied".

I share your thoughts about wondering what else is wrong with the computer.  I have rebuilt this beast twice now.  The 1st time all was cool until the customer came to pick it up, then we sat down to demo it and opened Firefox to view something, and the computer suddenly went a-wall.  I don't remember it's exact problems (it was about 2 months ago) but I do remember that it was like a virus.  I was about to leave on a 1 month trip so I stayed up almost all night rebuilding it again.  This time I left Firefox off and told the customer that I would resume the my setup on it when I returned.  

Upon returning I was told about this audio problem.  After finding the registry problem I told the customer that his restore partition must be compromised and that I would attempt to fix this one problem, but that he was going to need to prepare for the fact that he would need a new copy of the OS and a reinstall (at his expense) at some point in the future.  

At this point I'm just trying to solve this one problem to get free from this beast and the time it has so far consumed.  But yes, I think this computer is problematic.

qikkel - I checked that and it's all good.  No muting and volume is at 100%.

You could run something like Process Monitor, to filter for other Access Denied errors.... They might be there, but just not affecting your operation....

Process Monitor
http://www.microsoft.com/technet/sysinternals/utilities/processmonitor.mspx

Set the the filter at the top to Include "Result" is "Access Denied" then "Include", and just let it sit for a while...

Then you can get an idea if you have other issues.....

First let me say thanks to everyone for your input.  It is appreciated.  Ultimately though none of the suggestions resolved the problem, so I formatted and installed a known good copy of Windows XP Home Edition.  Problem solved.  

Conclusion - The Restore Partition OS image was corrupted in subtle ways.  It worked, but not completely correctly.  Shame on Sony for not regression testing their Restore Partition software.

The solution was my own idea, after trying all of the suggested ones, with no results.
