hi there ppl :)
i got a analogue wintv go with fm card (i think). It has radio for sure, 1x composite-in, audio
out, and an IR. I run ubuntu hardy 64bit system. tvtime xawtv etc work without a problem, only i
can't adjust the volume from within the applications. I have atm the line out of my tv card
connected to the line-in of my soundcard. That's how i get my audio from my tv card. In my old
computer however, with the same tv card and ubuntu feisty i got it working to get the audio from
the tvcard itself and not using the line-in of my soundcard, but i have no idea how i got that
working, i only know it took me while. Can someone help me with that please? :) here is some info
about my system:

card on http://www.bttv-gallery.de/ but they are so many that look so similar to mine... can
anyone help me to get the sound directly from my tv card?
thx in advance
