OK, thanks for that. That indicates you have a Sonia VGN-G11XN, running a 32-bit openSUSE-11.0 with the 220.127.116.11 default kernel with 1.0.16 of alsa. Hardware codec is an ALC262 on IRQ19.
I checked the mixer settings. Nothing really obvious strikes me as being wrong from that.
I note from the ALSA-Configuration.txt file, that came with the alsa 1.0.16 tarball the following for the ALC262:
fujitsu Fujitsu Laptop
hp-bpc HP xw4400/6400/8400/9400 laptops
hp-bpc-d7000 HP BPC D7000
hp-tc-t5735 HP Thin Client T5735
hp-rp5700 HP RP5700
benq Benq ED8
benq-t31 Benq T31
hippo Hippo (ATI) with jack detection, Sony UX-90s
hippo_1 Hippo (Benq) with jack detection
sony-assamd Sony ASSAMD
ultra Samsung Q1 Ultra Vista model
basic fixed pin assignment w/o SPDIF
auto auto-config reading BIOS (default)
And I note your /etc/modprobe.d/sound file:
You could try some entries in your /etc/modprobe.d/sound file, to see if it makes a difference. ie try change the file to:
options snd slots=snd-hda-intel
options snd-hda-intel model=auto
# u1Nb.1vrQ9SsoBKE:82801G (ICH7 Family) High Definition Audio Controller
alias snd-card-0 snd-hda-intel
Then restart alsa with rcalsasound restart and test your volume. Note once you hand edit your /etc/modprobe.d/sound file, do NOT go into YaST > Hardware > Sound, nor run alsaconf, as those will wipe your /etc/modprobe.d/sound custom settings
If “auto” does not work, then try one of the other parameters from the ALSA-Configuration.txt file for your ALC262, … ie try fujitsu, hp-bpc, hp-bpc-d7000, hp-tc-t5735, hp-rp5700, benq, benq-t31, hippo, hippo_1, sony-assamd, ultra, basic, … restarting your alsa after each change with rcalsasound restart and test your volume.
I also searched the alsa web site for a possible alsa update for the alc262. I obtained this: Search results fro ALC262 - AlsaProject
… which does not obviously indicated a “volume fix” for the alc262, although there are some alc262 updates. Hence you could try updating your alsa to 1.0.17. To do such an update, open a gnome-terminal / konsole (with your PC connected to the internet) and type ‘su’ (no quotes) to get root password (enter root password when prompted) then copy and paste the following in sequence, executing one at a time:
zypper ar http://download.opensuse.org/repositories/multimedia:/audio/openSUSE_11.0/ multimedia
zypper install alsa alsa-utils alsa-oss alsa-plugins alsa-tools alsa-firmware libasound2
zypper rr multimedia
zypper ar http://download.opensuse.org/repositories/multimedia:/audio:/KMP/openSUSE_11.0_Update/ multimedia
zypper install alsa-driver-kmp-default
zypper rr multimedia
then restart your PC to unload the old alsa modules and reload the new.
Then test your volume again, going thru all the tests/steps in all the posts above (including this one). I also note the 1.0.17 ALSA-Configuration.txt has an additional module for the ALC262 (for the Leonovo):
lenovo-3000 Lenovo 3000 y410
which likely is not relevant to you, although you could also try that “lenovo-3000” model in your /etc/modprobe.d/sound after retrying all the other models with 1.0.17 of alsa.
