Hm, I have an LG notebook with the same sound chip. Although it didn't work out of the box right after install, it did work just by itself without any further configuration at some point (few hours later, a reboot, don't remember exactly). Anyway, no special configuration changes to the intel hda kernel module were necessary. Sebastian, thanks, but I think the sound chip is very common and usually works. Just not on this particular notebook. It looks like a SND_PCI_QUIRK is needed in alc662_cfg_tbl in sound/pci/hda/patch_realtek.c. I can see that a lot of quirks has been added for 2.6.28 - but it isn't obvious if any of the new ones will solve this problem, and I don't have the system available for testing right now. I'm sure it would only take few seconds for a kernel developer to verify/solve this issue ... Problem remains with Fedora 11 and kernel-PAE-2.6.29.6-213.fc11.i686 Out of the box we get 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 hda_codec: Unknown model for ALC662, trying auto-probe from BIOS... ALSA sound/pci/hda/hda_codec.c:3507: autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3511: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3515: hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:3516: mono: mono_out=0x0 ALSA sound/pci/hda/hda_codec.c:3524: inputs: mic=0x18, fmic=0x19, line=0x1a, fline=0x0, cd=0x0, aux=0x0 But with /etc/modprobe.d/local.conf options snd-hda-intel model=3stack-dig options snd-hda-intel single_cmd=1 options snd-hda-intel enable_msi=1 we get sound and HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: irq 32 for MSI/MSI-X HDA Intel 0000:00:1b.0: setting latency timer to 64 ALSA sound/pci/hda/hda_codec.c:2698: hda_codec: model '3stack-dig' is selected I tested with the latest driver snapshot from alsa-project.org, and it works just fine "out of the box". Now I am waiting for a Fedora kernel with sufficiently new alsa drivers. The updated driver should be included in the latest kernel versions. Closing. |
