    No audio in 12.10

    Hey guys,

    I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working.

    Sound worked fine out of the box in 12.04

    I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix.

    It looks like Ubuntu is finding my audio device correctly.

    Code:
    mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW 
    (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp. Device 2668 Flags: bus master, 
    fast devsel, latency 0, IRQ 40 Memory at d01c0000 (64-bit, non-prefetchable) [size=16K] Capabilities: Kernel driver 
    in use: snd_hda_intel Kernel modules: snd-hda-intel
    My motherboard is an Albatron PX915G-Pro, am I correct in assuming that the alsa driver for this device is snd-intel-hda? It's kinda hard to see on this alsa page http://www.alsa-project.org/main/ind...x:Vendor-Intel

    Pulling my hair out on this one.

    same problem here, and this isnt a great solution (particularly on a clean install) but the 3.2 kernel still works.

    Hi,
    I am having a similar problem.
    After I upgraded from 12.04 to 12.10 audio worked perfectly fine, once I booted up my computer today, the start-up sound works fine and the change volume "sound" works, other than that no media audio plays at all.
    This is on 12.10 using gnome 3 (with a workaround to have it act like gnome 2 if this causes problems).
    Card is HDA Intel,
    and the chip is Realtek ALC888.


    Edit: (For anyone else with this particular issue only) It looks like it is a glitch if you switch your computer off if you leave the audio output to headphones, the computer reset it to the speakers, but the output was still technically set to headphones, switching to headphones and back fixed it.

    If alsamixer has correctly detected the soundcard, may be forcing Ubuntu to restart alsamixer will do the trick! Try this ...

    sudo alsa force-reload

    ^^ That fixed it for me. I just logged out and back in, had no sound and a "Dummy Output" showed up in Sound Settings.
    Then I entered sudo alsa force-reload and voila back to normal.
    Thanks!
