I posted the same issue on Plutohome forum but it's quiet a bit now. So, maybe somebody can help me solve my problem with ALSA drivers and SPDIF in my Plutohome 18.104.22.168 installation.
I setup MD based on Asus M2N Deluxe mother board. It has built-in sound including SPDIF but by some reason only analog was recognized by system. The same sound card works fine in the core/hybrid. I suspect that this problem is related with different version of ALSA. Because on the core/hybrid ALSA is 1.0.12:
dcerouter_19548:~# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.12.
Compiled on Mar 1 2007 for kernel 22.214.171.124-pluto-2-686.
but on MD - 1.0.11rc2:
moon153:~# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
I compared ALSA packages and they the same for both. So, i have no idea how to upgrade ALSA drivers on MD via apt.
Any suggestions will be highly appreciated!
