Audio

From A110 Wiki

alsamixer on A110 with stock 2.6.25 Debian kernel

The A110 contains a VIA HD audio controller with PCI ID 1106:3288, using the Realtek ALC268 codec.

amixer info produces ALC267 as the mixer chip. Since the only difference between 267/268 is the integrated system side of modem (for DAA module), the ALC267 is built into the IL1.

The hardware works fine using the snd_hda_intel ALSA driver (included in mainline 2.6.25).

Unmute the Front channel in alsamixer if you don't hear any audio.
