Hi,

the internal CD connector on my Asus M2N-SLI Deluxe board doesn't work without the patch below, /proc/asound/card0/codec#0 shows that the pin is disabled (Pin-ctls: 0x00).

I used kernel linux-2.6.24-rc4-190-g94545ba from Linus' git tree.

During my experiments I found that loading the snd-hda-intel driver with model=auto also enables the CD connector. It seems that for my board (BIOS version 1102) the BIOS configuration is correct and the "Asus M2N-SLI" quirk shouldn't be necessary? I get the following debug output:

ALSA sound/pci/hda/hda_intel.c:727: codec_mask = 0x1 ALSA sound/pci/hda/hda_codec.c:2140: hda_codec: model 'auto' is selected ALSA sound/pci/hda/hda_codec.c:2760: autoconfig: line_outs=4 (0x12/0x16/0x24/0x25/0x0) ALSA sound/pci/hda/hda_codec.c:2764: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:2768: hp_outs=1 (0x11/0x0/0x0/0x0/0x0) ALSA sound/pci/hda/hda_codec.c:2776: inputs: mic=0x17, fmic=0x14, line=0x15, fline=0x0, cd=0x18, aux=0x0

(which matches the board's actual connections)

Anyway, if you think the patch below is correct the please apply. It works fine for me.

There is one thing that I don't get however: If I run aplay it creates an additional "PCM" mixer control, which however doesn't have any effect. I guess this is intended for softvol, but I don't need it. How do I stop aplay from creating this control? (If it matters, I use Debian unstable, alsa-lib 1.0.15.)

Thanks, Johannes
