    SubjectRe: ac97, alc101+kt8235 sound (2.4.21-pre7-ac1)
    Seems that the VT8235 has some issues with ac97 recording.  Using aumix,
    and setting the input to line-in, cat /dev/dsp returns the same byte over
    and over again, as if there is no signal. Dumping this file and dumping
    back to /dev/dsp confirms the silence - no sound got record. Messing
    around with the mixer doesn't appear to do much. The mixer subsystem, I
    can control the volume of line-in and line-out, and hear the volume going
    up and down. I also tried Windows, seems it works fine in Windows.

    I tried the same command sequence on my SiS735 (i810-compatible) AC97
    machine and the results differ (it works :-) So it seems that there's
    something that's wrong with the kt8235 side of things?

    Playback works fine. Just cannot record. Is the kt8235 driver not quite
    primetime yet?

    Thanks,

    -bc
