    I had a problem with Ogle (my DVD player) and it turned out to be a problem
    with the sound driver I'm using. I found this email in an archive that lead
    me to the workaround:

    No I don't know if this chip works in linux.
    But this is a common problem that pops up from time to time
    in different audio drivers, nothing chip/hw specific.
    I suspect that driver writers forget that the device should "reset"/be able to
    accept new format settings after a
    SNDCTL_DSP_SYNC or SNDCTL_DSP_RESET ioctl,
    and not just after a new open of the audio device.

    Should I do anything like file a bug report? I don't know what these guys have
    done. btw on my system `uname -a` says
