Can't get SPDIF to work.

I am using Ubuntu 6.10 and using the onboard SPDIF from a ASUS P1-AH2.
My speaker out works fine, for some reason I can not get SPDIF to work.
I pull up ALSAMIXER and it only shows the option for PCM
Here is my output from aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: HDA Generic [HDA Generic]
Subdevices: 1/1
Subdevice #0: subdevice #0
I have read this page through
URL:www.mythtv.org/wiki/index.php/DigitalSoundHowTo
From recent posts it appears we no longer need to modify the .asoundrc file.
I'm not sure where to go from here.
Thanks
Mike

| In alsamixer I had to unmute "IEC958", set "IEC958 Playback AC97-SPSA" to level ZERO, and set "IEC958 Playback Source" to 'PCM'. But I'm not sure why you don't have those outputs in your alsamixer, they should be there if the drivers are working proper. |

Try using the Gnome Volume application to get to the alsa settings. It allows access to the same functions as alsamixer but the interface is to some a little easier to use.
The info in the last post is correct and SPDIF output won't work till these settings are changed.

please post /proc/asound/pcm and proc/asound/devices
alsa doesn't see any alternative outputs on your card, only device 0,0 |

as far as linux is concerned, you have no spdif output.
your machine has a very new chipset in it. you have to compile yourself the latest kernel to see if support for that soundcard has been included.
you could check the alsa dev and users mailing lists to see if there is any discussion on that chipset and or soundcard. |

Hi!
Same thing here...
my "aplay -l" result:

looks OK --> IEC958 (SPDIF is there)
but if i try to
"mplayer -ao alsa:device=hw=0.2 MatchesBox.mp3"
i get:

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:
Quote:
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... |
