#23 via audio mono recording does not work

misc PCI (4)

If recording mono via the via82cxxx_audio driver
version 1.1.14b (included in kernel 2.4.3) you get only
half-filled buffers (first half seems to be ok, second
half is just garbage). I attached a log (with VIA_DEBUG
defined) of a stereo recording session (which works ok)
and a mono recording session (which is broken). In the
.tar file is also a small .wav containing the resulting

    same problem for me (i listened to your .wave file). since i
    need mono recording for my tv card (which is mono), i
    switched to the alsa driver 0.5, which works fine

    This problem is fixed in the latest version of the driver. You
    can download the driver from the download section on this
    SourceForge web page.

    I'm using a clean 2.4.18 kernel with via82cxxx (v1.9.1)
    and got the same problem as described above.
    Stereorecording is wonderful but mono recording is broken.
    A visualising sound editor shows repeating excellent sound
    followed by data trash. Seems that the problem with half
    filled buffers is still present.
    Ideas ?
