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: HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: setting latency timer to 64 ALSA sound/pci/hda/hda_codec.c:2587: hda_codec: model 'auto' is selected ALSA sound/pci/hda/hda_codec.c:3303: autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3307: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3311: hp_outs=1 (0x15/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3312: mono: mono_out=0x0 ALSA sound/pci/hda/hda_codec.c:3320: inputs: mic=0x12, fmic=0x18, line=0x1a, fline=0x0, cd=0x0, aux=0x0 HDA Intel 0000:01:00.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17 HDA Intel 0000:01:00.1: setting latency timer to 64 alsactl[1631]: segfault at 0 ip 00000000004106e7 sp 00007fffb7682fa0 error 4 in alsactl[400000+14000] alsactl[1624]: segfault at 0 ip 00000000004106e7 sp 00007fff4ba9e3c0 error 4 in alsactl[400000+14000] The full output of the alsa-info script is here: http://www.alsa-project.org/db/?f=405364959a8f52c85f045f35fa1f3bf4536b13bc I have a working setup to compile the alsa-driver, so I'm ready to test whatever is needed :) Any ideas? Kind regards, Jin
