[SOLVED]intel_hda won't play sound on acer aspire 5315

I have an Acer Aspire 5315 but can't manage to play any sounds.

lspci reports the cards as

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

cat /proc/asound/card0/codec#*|grep Codec gives

Codec: Realtek ALC268
Codec: Generic 11c1 Si3054

What I have tried so far:

In kernel (gentoo-sources-2.6.23-r3) hda_intel module. Result:
module loads, alsamixer works (PCM, front, and headphones all moved off 0 and unmuted), aplay prints no errors, but no sound gets played

alsa-driver-2.14:
as above

alsa-driver-2.15:
as above

alsa-driver-9999:
as above

I can't remember the dmesg output for the other cases, but for alsa-driver-9999 I get

hda_codec: Unknown model for ALC268, trying auto-probe from BIOS...
ALSA /var/tmp/portage/media-sound/alsa-driver-9999/work/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/patch_si3054.c:238: si3054: cannot initialize. EXT MID = 0000
ALSA /var/tmp/portage/media-sound/alsa-driver-9999/work/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:583: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x10e90000

What else can I try? Is there any more output people need?

have you looked at the alsa mixer to verify the outputs arent muted? I think by default they are muted.

I have. As I said before, they are unmuted. PCM doesn't have a mute setting, but I'm guessing that's normal.

Try adding

Code: Select all

options snd_hda_intel model=acer

to /etc/modules.d/alsa
and run update-modules.
Then rmmod snd_hda_intel and modprobe snd_hda_intel.
Is everything ok?

I have tried your suggestion and I get exactly the same results as before except the last log line disappears (the one about the timeout).

Strange. I have:

Code: Select all

compal katoda # cat /proc/asound/card0/codec#0 | grep Codec
Codec: Realtek ALC268

And:

Code: Select all

compal katoda # lspci
(...)
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
(...)

And everything worked for me.
Please attach /etc/modules.d/alsa

EDIT: I have 2.6.23-gentoo-r1 kernel and alsa-driver-9999.

Just as I was about to post my /etc/modules.d/alsa, I checked and realized I had typed "option" and not "options"

. Sorry about that, and thank you very much for your help. It works now.
