SPDIF Not Working

[FC4ris]

Hello all,

I was wondering if anyone could help me with my SPDIF digital sound. Its an onboard sound card here are some lines that may help:


[root@localhost ~]# cat /proc/asound/devices
2: : timer
3: : sequencer
4: [ 0- 2]: digital audio playback
5: [ 0- 1]: digital audio capture
6: [ 0- 0]: digital audio playback
7: [ 0- 0]: digital audio capture
8: [ 0] : control


[root@localhost ~]# gedit /etc/asound.conf
#Generated by system-config-soundcard, do not edit by hand
#SWCONF
#DEV 0
defaults.pcm.card 0
defaults.pcm.device 2
defaults.ctl.card 0


And I get this error:

aplay -D hw:0,2 /usr/share/sounds/warning.wav
Playing WAVE '/usr/share/sounds/warning.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
aplay: set_params:906: Channels count non available


Plus no sound. The headphone audio jack works just fine. The sound quality is pretty bad though. I'm just trying to see if the Optical SPDIF port is better or if I have to install another sound card.

Please anyone with any ideas help me out. All my hardware and OS info are in my sig.

Hi guys!

I managed to get a REAL 5.1 sound form a CMI8**8 card!

Do not know which act, but, i set it like follows:
- the above mentioned settings are OK
- in alsamixer i set:

master - full
3d control -unmute
pcm - unmute
synt - unmute
line-mute
cd - unmute
mic - mute
mic-boos - unmute
phone - unmute
iec958 5v - unmute
iec958 c - unmute
iec958 in monitor - unmute
iec958 in phase reverse - mute
iec958 in select - mute
iec958 in valid - mute
iec958 - loop - mute
iec958 output - unmute
pcspeaker - mute
aux - mute
four channel mode - unmute

THEN, i started "soundcard detection" from Fedora GUI

and set the digital output as default...

the sound is great!

hope this helps...
