i have 7.10 with kernel 2.6.22-14-rt using a wintv card. i have the same problem: the line out of the wintv card is not working. well almost cause i can hear a little bit if i really boost the sound on my amplifier (+30db). i was hoping to use btaudio to driver the 32000 hertz to /dev/dsp2 (or so). but modprobe btaudio is not present. locate btaudio gives nothing. maybe it's my configuration.
