I have an ASROCK A330ION motherboard, and an amp on the optical S/PDIF output (5.1 setup). I installed dharma beta 1 from the Live CD image, everything worked fine. However, IEC958 stopped working after I ran an apt update... This can be reproduced.

I figured out that this is probably(?) a kernel issue, since the audio also goes away ("unable to initialize audio") if I reinstall beta1 and then upgrade only the system, not xbmc. It's pretty annoying...

This might be relevant, from xbmc.log:

aplay -l shows:

I think card0, device1 (iec958) is missing... it just went away. :|

After downgrading to linux-image-2.6.32-22-generic and installing linux-backports-modules-alsa-2.6.32-22-generic (also reinstaling nvidia-current) I got the sound working again.

aplay -l now shows:

Is "apt-update" a wrong thing to do with xbmc live?? :confused2:
