Intel HDA: Card detected, no sound.

I have a laptop with an Intel HDA (High Definition Audio), and though the card is detected well enough, there is no sound whatsoever. My user is in the "audio" group and I have unmuted everything. My laptop is a Toshiba Satellite A250. The card is (according to aplay) an ALC286.

Output of aplay -l:

[noam@noam-laptop ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Trying to play into specific non-default device:

 
[noam@noam-laptop log]$ aplay -D front /usr/share/sounds/startup3.wav 
aplay: main:545: audio open error: Device or resource busy

Does anyone have any idea what I can do? I looked in the ALSA documentation and they didn't mention any models for the ALC286.

Re: Intel HDA: Card detected, no sound.

OK, I found this patch, but I'm not sure how to apply it, and to what. My newbie-ish tendencies are showing through, I fear. Is it already applied in the upstream CVS/GIT/SVN/Whatever version of ALSA?

Edit: OK, I got the correct mercurial version of ALSA, but I don't know how to patch the kernel with it.

Re: Intel HDA: Card detected, no sound.

Good News:

Linus Torvald just merged with ALSA Head
(http://git.kernel.org/?p=linux/kernel/g … ;a=summary)

And six days ago support was added for the ALC268
(http://git.kernel.org/?p=linux/kernel/g … 4b3d69e15d)

So just wait for a new kernel release

[should be already in 2.6.23rc1]
