problem with alsa on Sony UX-90s

[Matthias Lemke <m@box.li>]

Hello,

i tried the last days linux on a sony UX90.
It is a very small notebook computer.

Sound works perfekt with headphones, but the internal speaker does not
his job.
I use als 1.0.13.

from dmesg:
[17179590.068000] hda_codec: Unknown model for ALC262, trying auto-probe
from BIOS...

any ideas?
