Hi, I am having constant problems with alsa and my sound card. The hardware in question is an Asrock 4coredual-sata2 motherboard, which houses an VIA High Definition Audio Controller (rev 10) that uses the alc888 codec.
The main problem is that either by random chance (which is usually frequently) or on an alsasound restart, alsa seems improperly recognize my sound card, usually trying to probe for an alc883 codec instead of an alc888 codec. This leads to me not being able to use the alsamixer, stating that there are improper channels defined. I've also added pci=noacpi to my grub.conf to see if that fixed any of the dmesg errors i get, but to no avail. I've included the pastebin link to alsa-info , and included in this email my relevant dmesg and lspci info. I am using gentoo linux, and the alsa-driver package (alsa-driver 1.0.16_rc1, alsa-lib 1.0.16_rc2, alsa-util 1.0.16_rc1) The built in kernel driver for the 2.6.24 kernel also has the same problem, so i upgraded to the latest stable alsa driver to see if that would fix the problem. pastebin link for alsa-info: http://pastebin.ca/914405 relevant dmesg: hda_codec: num_steps = 0 for NID=0xd (ctl = Surround Playback Volume) PCI: Setting latency timer of device 0000:80:01.0 to 64 ALSA /var/tmp/portage/media-sound/alsa-driver-1.0.16_rc1/work/alsa-driver-1.0.16rc1/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:587: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x129f0009 ALSA /var/tmp/portage/media-sound/alsa-driver-1.0.16_rc1/work/alsa-driver-1.0.16rc1/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:594: hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x129f0009 hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... hda-intel: Invalid position buffer, using LPIB read method instead. lspci 00:00.0 Host bridge: VIA Technologies, Inc.
