on-board sound on ASUS TRX-40

[Dan Aloni <dan@kernelim.com>]

Hi,

The on-board earphone jack does not seem to work on an ASUS TRX-40
board. Here's the alsa-info.sh output:

http://alsa-project.org/db/?f=7a94c1b1eec4b2e623c75770364ec43c33d6c95c

Tried coding up the patch below, but it _does not_ fix the problem. It
does shows the earphone as 'plugged' though. Verified that it's not an
hardware issue via Windows.

Please instruct on how to debug this further.

Thanks!
