[Voyage-linux] Audio problem with US15W intel chipset

[Jukka Väyrynen]

HI all!
I have a comexpress module which have a intel US15W chipset inside. I have compiled a custom kernel 2.6.31.13 which works with intel  GMA-500 graphics driver and internal sata module. However I have a weird problem with audio. Sound works for awhile, lets say about 3 hours and then it disappears. If I execute command  "cat /proc/asound/card0/codec#0 | grep Codec" sounds comes back and following messages comes to dmesg

ALSA hda_intel.c:712: azx_get_response timeout, switching to polling mode: last cmd=0x001f000a
ALSA hda_intel.c:751: hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x001f000a

lspci says:
00:1b.0 Audio device: Intel Corporation System Controller Hub (SCH Poulsbo) HD Audio Controller (rev 07)

Audio Codec is
Realtek ALC268

I have compiled debugging audio drivers but still do not get any messages to log when sound disappears

Any thoughts?

Regards, Jukka Väyrynen
