I analyze sound source switching in my good working driver for
Windows and it do next (see below...). By this expirience, I prepare
next patch for msp3400.c, whitch work much better then my
previous patch. (good working mute/unmute on external source, etc.)
Windows drive do this for all Tv cards using MSP3400 chip. It
maybe working good for all other cards under BTTV.
