Date: Sun, 18 Jul 2010 22:08:53 +0530 From: David John <davidjon@....com> To: Takashi Iwai <tiwai@...e.de> CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: Multiple Codec Problem With Intel HD Audio Hi Takashi-san, I have a custom Atom Poulsbo based board on which I am running 2.6.34. The board has an ALC888 connected to the Intel HD Audio controller for the main speakers and another ALC888 on a daughter board connected to the same controller for additional headphone and mic jacks. On boot I get the following: hda_codec: ALC888: BIOS auto-probing. ALSA sound/pci/hda/hda_codec.c:4358: autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:4362: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:4366: hp_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:4367: mono: mono_out=0x0 ALSA sound/pci/hda/hda_codec.c:4378: inputs: mic=0x18, fmic=0x0, line=0x1c, fline=0x0, cd=0x0, aux=0x0 ALSA sound/pci/hda/patch_realtek.c:1287: realtek: No valid SSID, checking pincfg 0x40120601 for NID 0x1d ALSA sound/pci/hda/patch_realtek.c:1303: realtek: Enabling init ASM_ID=0x0601 CODEC_ID=10ec0888 input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input7 hda_codec: ALC888: BIOS auto-probing.

I have noticed that in the kernel Intel HD audio documentation, you have mentioned: "In theory, there might be multiple audio codecs, e.g. for analog and digital outputs, and the driver might not work properly because of conflict of mixer elements. This should be fixed in future if such hardware really exists." I believe this is the problem I am hitting? Is there a fix available for this? I have attached the codec info from /proc. P.S: The hardware is okay since in Windows I can get both codecs to work (one active at a time) even though I have to manually change the default hardware setting. Regards, David.
