[GA-790FXTA-UD5, Realtek ALC889, SPDIF Out, Internal] No sound at all

[Robert Hrovat]

Sound over SPDIF does not work correctly with Natty Beta 2. The only sound I get is from analog speakers but if I choose IEC output, sound goes only to HDMI but never to SPDIF.

It worked with Live CD 10.10 where sound was produced on SPDIF, HDMI and analog outputs.

Somehow I managed to make it work. I have no idea how but I was trying different things for the last 4 hours. Last time I remember was making two changes:

1.) in /etc/modprobe.d/alsa-base.conf added line
options snd-hda-intel model=6stack-dig

2.) installed gnome-alsamixer and checked IEC958 Default PCM (it seems suddenly selecting IEC958 is not enough, but that's what mixer applets offers)

There should be either same defaults as with previous releases or sound/mixer applets should have options that doesn't seem to exist in installed ones.

Now I found the right bug report!!!
