Yesterday I was doing some extra tests. With aumixer I get three connections under btaudio: Line[1-3]. The audio capture works just the same no matter which device I set as the record device. The volume control affects the recording though (I have to leave the volume level really low not to get any noticeable distortion). BTW, I have tested two other boards: a very old board autodetected by bttv as "(Askey Magic/others) TView99 CPH05 x [card=3D24], PCI subsystem= ID is 144f:3002" and another Prolink PlayTV Pro, this time revision 9D. With the Askey Magic I got only silence but with the Prolink PlayTV Pro revision 9D I got bad sound with btaudio. By bad I mean a slightly high pitch soundI got the sound of the TV with a slightly higher pitch than usual and with more than usual noise during silence. The sound was bad but at least I got something. Today I found another BT878 board for sell here in Brasilia: Pinnacle PCTV. I could have tested it also but I got lazy. The store I found all these boards are a little distant from my work and I have already tested= 5 different boards. Do you think there is any chance for these boards to work with btaudio and/or snd-bt87x? BTW, is there some kind of list with boards that work with btaudio and/or snd-bt87x?
