ASU and sound - broken - how to fix it?

[Torfinn Ingolfsen]

Hello,
I am running ASU (daily builds) on my FR.
Sound has been broken for a while now. When I do 'demg | grep snd' I get this:
root at om-gta02:~# dmesg | grep snd

How do I fix the problem?
I did a 'opkg update && opkg upgrade' just now, but that didn't
improve anything.
