No windows sounds after uninstalling FFDshow

I have kind of an odd situation that happened yesterday. I was just doing some routine maintenance, cleaning off a few programs I don't really use on this computer, and defragmented my hard drive. I don't think any of the programs were anything that had to do with sound, except for FFDshow, so I am going blame that as the culprit. Basically, none of my normal windows startup/shutdown/beeps or sounds work, however I can play music and stuff just fine in Winamp or Windows Media Player. Another odd thing, which is probably linked to this, is that I can not adjust the volume with my keyboard controls anymore, however I can adjust it in the NVIDIA NVmixer in the taskbar.

Basically thus far I have reinstalled FFDshow to see if that helped, which it didn't. I uninstalled the NVidia NForce4 drivers and reinstalled, that didn't work. Manually installed a few of the default audio codecs, which all had been erased (when checked in Control Panel/Sounds and Audio Devices/Hardware/Audio Codecs/Properties) everything was gone. So I found a website which told how to reinstall default audio codecs, and did so - but still no success. I know it is not a huge deal to not have startup sounds/beeps/etc, or to not be able to adjust the volume with the keyboard, but it is still annoying enough to get under my skin. I don't assume anyone else has ever had a similar problem or might know how to fix this without doing a whole fresh installation of Windows? Thanks in advance!

Try this registry script. Taken from a clean XP SP2 install. That should fix your system sound problem.

Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"midimapper"="midimap.dll"
"msacm.imaadpcm"="imaadp32.acm"
"msacm.msadpcm"="msadp32.acm"
"msacm.msg711"="msg711.acm"
"msacm.msgsm610"="msgsm32.acm"
"msacm.trspch"="tssoft32.acm"
"vidc.cvid"="iccvid.dll"
"vidc.i420"="msh263.drv"
"vidc.iv31"="ir32_32.dll"
"vidc.iv32"="ir32_32.dll"
"vidc.iv41"="ir41_32.ax"
"vidc.iyuv"="iyuv_32.dll"
"vidc.mrle"="msrle32.dll"
"vidc.msvc"="msvidc32.dll"
"vidc.uyvy"="msyuv.dll"
"vidc.yuy2"="msyuv.dll"
"vidc.yvu9"="tsbyuv.dll"
"vidc.yvyu"="msyuv.dll"
"wavemapper"="msacm32.drv"
"wave"="wdmaud.drv"
"midi"="wdmaud.drv"
"mixer"="wdmaud.drv"
"aux"="wdmaud.drv"
"msacm.msaudio1"="msaud32.acm"
"msacm.sl_anet"="sl_anet.acm"
"msacm.iac2"="C:\\WINDOWS\\system32\\iac25_32.ax"
"vidc.iv50"="ir50_32.dll"
"msacm.l3acm"="C:\\WINDOWS\\system32\\l3codeca.acm"

You are my new best friend for the day! Worked like a charm, at least in getting my sounds back. For some reason I still can't adjust the volume with the keyboard. I uninstalled and reinstalled MS Intellitype already. Any suggestions (or registry scripts?) to fix that?

Gracias!
