You've got to remember that xawtv just mutes and unmutes the line in, it doesn't generate or process the sound data at all, the signal is fed into the line in as analog and sent straight back to the line out without being digitised (well, it *might* be, point is the ap doesn't touch the sound) In KDE (You mention it somewhere else in the thread) you can do what xawtv does - mute and unmute chanels - from the input pane of kmix. Try unmuting it manually when there's a signal coming from the tv card. If you plug headphones directly into the tvcard's line out and there's no signal I can only assume it's borked. Some cards have an internal volume setting (in addintion to the input volume onthe sound card) - the only program I know which can change this is tvtime, however most cards come with it at 100% percent by default and I can't think of a good reason it'd have been changed. > Yes, I do have that setup where an external cable that runs into the > sound card. I do not have the DV card.
