    I run it in Puppy Linux also.

    olexandr, did U solve the problem? Notice when you run: cat /proc/asound/cards
    Do the devices switch numbers after booting at different times? Also, did U try alsamixer -c # ? Where # is one of those numbers.
    I should not be writing this as I HATE ALSA, nevertheless, did U run alsaconf and alsactl store?
