I just want to confirm that I have the same problem on Debian. It works perfectly with the regular Debian 2.6.32 kernel with the 1.4.1 ivtv driver but is unusable with the 2.6.37-rc7 kernel in Debian/experimental. I ran ivtvctl -a on both kernels and diffed them: mythtered% diff ivtv.out-2.6.32 ivtv.out 10c10 < Driver version: 66561 --- > Driver version: 66562 202c202 < Volume = 60928 --- > Volume = 58950 206a207 > Loudness = 1 Messing with the volume doesn't make any difference for audio quality. I don't know what the "Loudness = 1" setting means or how to modify it. I also tried disconnecting the audio input to the card so it should have been recording only silence, but the loud hiss was still there. I'll try to investigate this further soon.
