Hardy 8.04: No sound for Intel Q35 ALC883 audio

[lptr]

[Solved] I played around with mixer settings again. Well - that's it. Sound working, now.


Successfully installed 8.04 Kubuntu on a 4 GByte USB stick as a full installation. Not a Live-CD transfer! (see here: http://ubuntuforums.org/showthread.php?p=4831104#post4831104#27 (http://http://ubuntuforums.org/showthread.php?p=4831104#post4831104#27))

When I started on the desktop system I definitively heard a sound. This has been gone since I rebooted first time. asound mixer settings all ok.

dmesg tells me:

hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...nothing else.

Found this in the hardware manual for mainboard:
Realtek ALC883 8-channel High Definition Audio CODEC with Jack-detection support, Enumeration and streaming

Some further search lead me to this:

$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfe970000 irq 23

# cat /proc/asound/modules
0 snd_hda_intel
So it seems that something did find and initialize it at least once.

Anywhere online I found that Jack-detection having some issues.

Anyone knowing something regarding? Is there a known workaround so sound works?

Thanks in advance

I have a GA-965P-DS3 with the same chipset audio and using Ubuntu (Gnome) Hardy without sound. I found a thread that suggested a fix as seen here http://ubuntuforums.org/showthread.php?t=687726 by getting module assistant to rebuild alsa then issuing a

sudo /etc/init.d/alsa-utils reset

i get the following:

* Resetting ALSA... amixer: Invalid command!
[ OK ]

something of note, when i logged into GDM this boot, i heard a sound, going into the desktop though i hear no starup sounds and unable to play soundfiles.

would appreciate any help anyone can give.

edited. tried sudo /etc/init.d/alsa-utils start instead of 'reset' and get the following error:

@sputnik:~$ sudo /etc/init.d/alsa-utils start
* Setting up ALSA... * warning: 'alsactl restore' failed with error message 'alsactl: set_control:989: warning: name mismatch (IEC958 Capture Switch/IEC958 Default PCM Playback Switch) for control #35

alsactl: set_control:993: failed to obtain info for control #35 (Operation not permitted)'... amixer: Invalid command!

please help. thank you

I had somewhat the same issue. I unistalled anything pulse audio in synaptic. Now it all works.
