When VFW application (like VDub, freeVCR etc) is started under W2K/XP it cannot enable sound and goes mute sometimes.
Here is a little program which allows to enable/disable sound on video capture card. You can put this puppy into cmd file for running your application prior to it or run it separately.

=======
Some applications, designed for old VFW interface (VirtualDub, FlyCap, Vidcap32 )
may lose sound when running under Windows2000 or XP with some WDM drivers.

SoundOn application allow you to control audio input pins on WDM driver crossbar.
Examples:

SoundOn.exe without parameters (tuner audio in)
SoundOn.exe -1 (mute)
SoundOn.exe 0 (tuner audio in)
SoundOn.exe 1 (line audio in)
SoundOn.exe 2 (line audio in)
SoundOn.exe 3 or more (tuner audio in)
