  1. Onboard CMI 8738 Audio Issues...

    Hello all. I installed Debian 4 on an Athlon box with a CMI 8738 sound
    chip, and it all works perfectly except for the audio. Anything that
    attempts to play audio results in a hard crash - nothing short of
    physically pushing the reset or power button will recover it.

    AlsaMixer seems to detect the audio hardware just fine, displays the
    proper card, chip, and so on. Everything is unmuted. I'm not terribly
    familiar with how sound hardware works under Linux - perhaps I'm
    missing something somewhere?

    This system was used as a FreeBSD server for years, but it being a
    server, I never tried out the onboard audio. Is it possible this is a
    hardware problem? Is there a simple way I can test the physical audio
    hardware?

    Thanks for your help!
    Dustin

    And one more data point to this issue - I did an install of both
    OpenSuSE and Ubuntu, and they do exactly the same thing. So I'm
    thinking that my hardware isn't completely compatible with the 8738
    driver used in ALSA. I dunno...the motherboard is a Soyo KT400 Lite,
    if that matters.

    Thanks again!

    Are you sure the onboard soundcard is not disabled in bios? Are there
    any error messages? Aplay test.wav produces what error messages? Boot
    messages from sound device? Worse case, buy a $20 pci soundcard.


    The cm3738 uses intel8x0 drivers so it's straight forward.

    /etc/modprobe.d/sound
    options snd-cmipci enable=1 index=0
    options snd-intel8x0 enable=1 index=1


    # gZD2.leFtcOMtGx0:CMI8738/C3DX PCI Audio Device
    alias snd-card-0 snd-cmipci

    Yeah, it was enabled in bios, and playing test.wav just crashed the
    box in the same manner. So I went out and got a $12.99 sound card from
    Fry's - same chipset and everything - and it works great! Must have
    been a hardware issue I guess.

    Thanks for your help!
