[gentoo-user] coax spdif sound output on Intel 82801EB/ER audio

[Iain Buchanan <iaindb@netspace.net.au>]

Hi all,

I used to (rarely) use the coax output on my Dell Inspiron 9100 laptop
to feed into my hifi.  Now that I watch a lot more movies / tv from my
laptop, I wanted to get it going again, but I no longer get any output
from the coax out.

Investigating google a bit, I found that this works with mplayer:

mplayer -ao alsa:device=spdif -srate 48000 blah.mp3

giving me crystal clear audio (I had to mute it to make sure there
wasn't someone in my house, cause the sound effects on the audio track
were so realistic!)

how do I get it to work by "Default" for everything alsa? (gnome,
rhythmbox, etc)

I tried playing around with all the options I could see in
gnome-volume-control, no luck.

google suggested setting IEC958 playback to 0 (yes, zero) which worked
for others, but firstly this setting was never saved with
gnome-volume-control or even alsamixer, and secondly, it didn't seem to
have any effect.

Unfortunately, I can't tell you anything about my system when it did
work like this (it was a while ago), only that it doesn't anymore.

Here are the specs:
Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev
02)
pci-id 8086:24d5

suspend2 sources 2.6.17-r5, with alsa built as a module (snd_intel8x0).

Can anyone shed any light on the issue?

many thanks,
