I have bttv as released with kernel 2.4.0 STB2 TV tuner xawtv 3.3.0 I can change/mute the audio with no problem . However, if I exit xawtv with the audio on the audio of the last channel tuned to continues to play . It will continue to play through a reboot . My only work around is to mute before exiting xawtv . Many Tanks John
