Hi,
I recently bought an Intel DH55TC motherboard, and I can't get the sound card to work.
The sound card is:
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
with a Realtek ALC888S codec chip.
Output from dmesg:
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: irq 28 for MSI/MSI-X HDA Intel 0000:00:1b.0: setting latency timer to 64 hda_codec: ALC888: BIOS auto-probing. autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) speaker_outs=1 (0x15/0x0/0x0/0x0/0x0) hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) mono: mono_out=0x0 dig-out=0x1e/0x0 inputs: mic=0x18, fmic=0x19, line=0x1a, fline=0x0, cd=0x0, aux=0x0 realtek: No valid SSID, checking pincfg 0x4016c629 for NID 0x1d realtek: Enabling init ASM_ID=0xc629 CODEC_ID=10ec0888
The snd_hda_codec_intelhdmi and snd_hda_codec_realtek modules are loaded, but there is no /proc/asound/modules file and any program trying to use sound says there is no sound card.
I tried all of the models listed under ALC888 in HD-Audio-Models.txt, but none of them worked.
I tried with a 2.6.32 kernel from Debian, as well as with a 2.6.33-rc6 kernel and with the sound-2.6 tree from git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git pulled on top of a 2.6.33-rc6 kernel, and the results were the same in all three cases.
If I compile snd_hda_intel in the kernel, I get the lines:
ALSA device list: #0: HDA Intel at 0xfe420000 irq 28
after the lines from HDA quoted above in dmesg, while when it's compiled as a module I get:
ALSA device list: No soundcards found
before those lines, but apart from that the behavior is the same.
Attached is the output from alsa-info.sh.
