Hi,
there's been a thread about a similar issue around 2008-04, it ended with a
working front left/right setup, which is of course better than no sound, but
it would be really nice to be able to use all available speakers.
The notebook has 5.1 surround, but all speakers except front left and front
right stay silent.
I'm running Fedora 10, 2.6.27.9-159.fc10.x86_64,
# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.18a.
# cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfc300000 irq 22
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xc7eec000 irq 17
When I select model "auto", then I get a working front left and front right
speaker. When I select model "acer-aspire", everything is mute and I have
to use the hda-verb utility to get some sound out of the front speakers, so
right now I am using the "auto" option.
I see a segfault in alsactl when I look at dmesg, not sure if this is
related to the problem:

The full output of the alsa-info script is here:

I have a working setup to compile the alsa-driver, so I'm ready to test
whatever is needed :) Any ideas?
Kind regards,
Jin
