Vista/Win7 appear to persist the sound level settings per application. I'd like to have a look at that list.
The reason? According to a Microsoft blog, the settings are stored against the PID of the application, and I'd really like to find out what that PID is. I'm having trouble isolating which process is 'registering' itself with the Volume Mixer.
Answer
Windows 7 does persist the audio settings for applications in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\LowRegistry\Audio\PolicyConfig\PropertyStore
There are lots of sub-keys with numeric names. The settings are indexed by full application path so search for the name of your application in there.
I needed to find this because my Media Player Classic suddenly stopped producing any sound, and in a way which I figured couldn't be caused by a mis-configuration on my side. Finding a key containing mplayerc.exe and deleting it fixed the problem.
