Thanks for your response, Martin.
The Line is set as a capure device. I got my xawtv unmuted and I'm still not getting any
sound. I used to get it a couple of weeks ago, just after changing OSS drivers for the
ALSA ones (so I believe it is not an ALSA problem, I got all sound files played fine) But
one day, I started to change the values of the alsamixer (following myth howto
indications) and, somehow, I muted the analog output of the bttv TV card. So I have the
funny feeling that my alsamixer values are not ok, but I just can't find the appropiate
configuration.
Any help would be really valuous,
Xavier
