OK, thanks for that. I note a Gigabyte EP45-UD3R running the 220.127.116.11-0.5-default kernel on openSUSE-11.0, with 1.0.16 of alsa, where the Gibabyte’s hardware audio codec is an ALC882 or 885.
I checked your mixer settings and noted they appeared to be ok for playing audio, although the master volume at 69% could be moved up to 95% for testing, and then backed off once sound is established.
I checked the alsa web site for updates for the ALC885: Search results ALC885 - AlsaProject and for the ALC882: Search results ALC882 - AlsaProject and since 1.0.16 of alsa there were not many for the ALC885 but there were some for the ALC882.
Still, its possible we can get this to work without updating alsa.
My speculation is that the auto probe of alsa upon booting, failed to properly configure your alsa sound driver. So I recommend you try iteratively forcing different model configurations, to see if one of those will give you sound. You can do that by editing your /etc/modprobe.d/sound file as I will describe below.
Note to edit this file requires root permissions. You can edit it:
- in Gnome by typing: gnomesu gedit /etc/modprobe.d/sound
- in KDE by typing: kdesu ‘kwrite /etc/modprobe.d/sound’
and enter root permissions when prompted.
When editing the file, we are going to chose an option from the following list from the 1.0.16 alsa-configuration.txt file:
3stack-dig 3-jack with SPDIF I/O
6stack-dig 6-jack digital with SPDIF I/O
arima Arima W820Di1
targa Targa T8, MSI-1049 T8
asus-a7j ASUS A7J
asus-a7m ASUS A7M
macpro MacPro support
mbp3 Macbook Pro rev3
imac24 iMac 24'' with jack detection
w2jc ASUS W2JC
auto auto-config reading BIOS (default)
Lets start with “3stack-dig”, test, and if that does not work we will then replace that with the next item in the list, test it, and if that does not work, keep working our way thru the list.
So, as described above, to test “3stack-dig”, open the /etc/modprobe.d/sound file with root permissions with the edit, and add a line AT THE START of the file, so that the file now looks like:
options snd-hda-intel model=3stack-dig
options snd slots=snd-hda-intel
# u1Nb.d+x9W4UhE78:ICH10 HD Audio Controller
alias snd-card-0 snd-hda-intel
save that change.
Then in a terminal restart your alsa sound driver with the command su -c ‘rcalsasound restart’ and enter root password when prompted, and restart your mixer (kmix on KDE and alsamixer on Gnome) and then run the 3 speaker tests that are noted in the audio troubleshooting guide (you tried 2 of them before). Test your sound. Do you get sound?
If not, then in the /etc/modprobe.d/sound file, replace “3stack-dig” with “6stack-dig” , save the change, and again, in a terminal restart your alsa sound driver with the command su -c ‘rcalsasound restart’ and enter root password when prompted, and restart your mixer (kmix on KDE and alsamixer on Gnome) and then run the 3 speaker tests that are noted in the audio troubleshooting guide (you tried 2 of them before). Test your sound. Do you get sound?
Keep trying each item in the list until you get sound or until you exhaust the list.
