(SCH Poulsbo) HD Audio Controller

(SCH Poulsbo) HD Audio Controller

[Victor Stinner]

Hi,

I bought a new Eee PC 1101HA. It uses the "Intel System Controller Hub 
(SCH) US15W" chipset which includes the "ALC269" (Intel "HD" audio 
chipset). The pci identifier of the audio sound card is 8086:811b. On 
Fedora, the snd-hda-intel kernel (from ALSA 1.0.20) module is loaded, 
but i don't hear anything.

On IRC (#alsa on Freenode), gnubien gave me the trick to make it 
working: write the following configuration in /etc/modprobe.d/alsa.conf 
file:

    options snd-hda-intel model=eeepc-p901

Without the model trick, my playback controls are:

- Master
- Headphone
- PCM
- Front
- Front Mic
- Front Mic Boost
- Beep

With model=eeepc-p901, playback controls are:

- LineOut
- Mic Boost
- Beep
- iSpeaker

Thanks to model=eeepc-p901, the sound works correctly.

Here is the output of alsa-info.sh script:

Using http://www.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-20091106.tar.bz2,
do you still need the model quirk?

Could you point me a documentation explaining how to compile/install the 
tarball?

Note: I'm now using Fedora 11.

Note 2: I subscribed to the mailing list, so you don't need to CC-me to you 
anwsers anymore.
