    Acer Aspire One - Sound not working

    Ubuntu 8.10

    Sound was working when I first booted windows. Installed Ubuntu 8.10 using unetbootin. I can't seem to get sound working at all. PCM volume is up, nothing is muted in alsamixer. I recompiled alsa-driver, lib, and utils.. no good results.

    I am seeing this in dmesg:
    HDA Intel 0000:00:1b.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

    ---------------------------------

    in /etc/modprobe.d/alsa-base, I appended this as the last line:
    options snd-hda-intel model=auto (tried model=acer too)

    Other folks seem to be getting sound to work out of the box on this notebook. I can't figure out what I am missing. Any tips?

    I tried recompiling the alsa drivers with all cards and added the following line to /etc/modprobe.d/options:

    "options snd-hda-intel model=acer-aspire" (no quotes)

    Still no change... I always have to do a "make install" after recompiling alsa for the wifi or wireless stops working too.

    volume on everything is up.. nothing unmuted. Man I am stuck. I don't know what else to try.

    Sound works OOTB in Jaunty. Alternately, you could apply kernel 2.29 and ALSA 1.0.19 to your Intrepid install to get sound working.

    But it's simpler to just install Jaunty

    Thank you! I did compile/install alsa 1.0.19 but it still didn't work.

    I ended up loading Jaunty using the netbook remix image (https://wiki.ubuntu.com/UNR) and this was MUCH easier. Sound works and the wireless networking worked out of the box.

    I am extremely impressed at the cost and performance of this setup.

    The external mic isn't working yet but that seems to be a universal flaw at this point.

    Thank you again for your suggestion!
