I note your PC has the 32-bit openSUSE-11.1 with the 2.6.27.29 kernel and 1.0.17/1.0.18 of alsa. Your Gigabyte's hardware audio codec is an ALC889A.
I searched the alsa web site for the ALC889A and noted some updates since openSUSE-11.1 was packaged: Search results - AlsaProject - ALC889A
I also note that some users reported the 2.6.27.29 kernel update broke their sound.
So if the above speaker tests don't work, and you tried my 95% volume level suggestion for your mixer, and you still have no sound, then you can try updating your PCs alsa sound driver for openSUSE packaged for the 2.6.27.29 kernel. The guidance for that is here: Alsa-update - openSUSE Note you must send six zypper commands.
In your case, in a terminal/konsole, with your PC connected to the internet, with root permissions, copy and paste the following six zypper commands, in sequence, sending them one at a time:
Code:
zypper ar http://download.opensuse.org/repositories/multimedia:/libs/openSUSE_11.1/ multimedia
Code:
zypper install alsa-utils alsa-plugins alsa-plugins-jack alsa-firmware alsa alsa-plugins-samplerate alsa-tools alsa-plugins-pulse alsa-tools-gui alsa-oss alsa-docs libasound2
Code:
zypper rr multimedia
Code:
zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.1_Update/ multimedia
Code:
zypper install alsa-driver-kmp-pae
Code:
zypper rr multimedia
Then restart your PC and test your sound. Use the speaker tests noted. If that does not work, there are also daily snapshot updates that can be applied.
