Re: [ls-support] Re: Just in case.. New Install
  • Hi Bjorn,

    I've been traveling, so I haven't had the time to respond to your mail
    quickly.

    I'm also sorry to hear about your frustration with ALSA. In my own
    experience, I've had the best/easiest time using external USB sound cards,
    which rely on the same driver for all cards. I've used two external sound
    cards (a Roland and a SoundBlaster Extigy USB and both have worked fine).

    There are certain SoundBlaster cards known not to work with ALSA, however.
    (I think it's especially the SoundBlaster Audigy that causes the most
    problems). Your PCI cards may be among them.

    The ALSA project documentation has an extensive list of hardware and
    whether it is known to work (or not). You can find that at this address:

    http://www.alsa-project.org/alsa-doc/index.php?vendor=All#matrix

    Another odd thing about ALSA sound has to do with ALSA notation when
    setting up the sound card, either in the new gLiveSupport's Options->Sound
    menu or directly in the scheduler.xml and gLiveSupport.xml config files:
    For whatever reason, I get sound when I install the alsa-oss module and
    then use OSS-style notation, i.e. /dev/dsp, /dev/dsp0, /dev/dsp1, etc.

    I don't know also if you've checked our 'Cheat Sheet' document, which
    outlines several command-line steps you can use with LiveSupport, including
    how to identify your sound card assignations. That document is at:

    http://code.campware.org/projects/livesupport/wiki/CheatSheet

    the command to use from that document would be 'cat /proc/asound/cards',
    which will give you output like this:

    0 [V8237 ]: VIA8237 - VIA 8237
    VIA 8237 with ALC650F at 0xec00, irq 22

    The important thing is that first number, which you can use to identify the
    sound card location, such as /dev/dsp0 or plughw:0,0.

    Improved sound card identification is one of the nice features in the new
    1.1 release, which should be out in the next few weeks if all goes well.


    Hope this helps,


    douglas

  • Thanks for the reply. I may actually go and get some USB devices, then. I haven't rebuilt the machine yet, so I may be in luck. I'm not giving up, just extending the deadline...

    Thanks again.
