[alsa-devel] Fwd: No sound with ATI SB450

[Ben DiDonc]

Tobin,

>Which snapshot did you download?

I used alsa-driver-hd20070421

possible that your audio is disabled in bios?

I agree with you. This laptop has a strange BIOS, you can disable a couple
of things (network card,...) but not the sound card.

"acpi=off" on the kernel boot parameters list.

No  improvement here, no difference with what I had before... still no sound
...

To help us debug this further if the above steps don't work, try recompiling

Ok, I rebuild the drivers with the configure options you gave me, and
reloaded them. I grepped my syslog and got a single line out of it:
Apr 22 19:07:50 tosh-it kernel: [89422.940000] ALSA
/media/sda3/gilles_files/download/drivers/alsa-driver-hg20070421/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:696:
codec_mask = 0x9

but still no proper senses shown in alsamixer and no sound. See output of
alsa-info.sh at http://pastebin.ca/452475

Your system "should" show up as a Toshiba with RealTek ALC861 audio codec.

I did a bit of research on the devel mailing list and found
http://article.gmane.org/gmane.linux.alsa.devel/45881
I tried applying the patch (to hda_intel.c) and realised most of it already
was in the snapshot EXCEPT line 995, which i replaced with the one from the
patch. It now is
for (c = 0; c < azx_max_codecs[chip->driver_type]; c++) {

 I rebuilt the whole lot, reloaded snd_hda_intel and got these two lines
this time:

Apr 22 19:39:01 tosh-it kernel: [91293.576000] ALSA
/media/sda3/gilles_files/download/drivers/alsa-driver-hg20070421/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:696:
codec_mask = 0x9
Apr 22 19:39:01 tosh-it kernel: [91293.916000] ALSA
/media/sda3/gilles_files/download/drivers/alsa-driver-hg20070421/pci/hda/hda_codec.c:1819:
hda_codec: model 'toshiba' is selected for config 1179:ff10 (Toshiba)

This time the right codec is loaded (or so it seems), alsamixer only shows a
PCM control (for playback), but there is still no sound. alsa-info.sh output
at http://pastebin.ca/452493

I m a bit confused with these results...
