[SOLVED] No sound for optical / spdif output with alsa

When running speaker-test I get no sound from my speakers no matter what options I try in alsamixer.

Here is some info:

aplay -l

Re: [SOLVED] No sound for optical / spdif output with alsa

.asoundrc:

defaults.pcm.card 1
deffaults.pcm.device 0
defaults.ctl.card 1

Is this really what you have in .asoundrc? The second line has a typo ("deffaults") -- have you tried without this file?

Re: [SOLVED] No sound for optical / spdif output with alsa

I did have that typo on my .asoundrc, but I just removed it and I still don't get any audio. I do here a slight popping noise when I mute and unmute s/pdif 0 in alsa mixer.

Re: [SOLVED] No sound for optical / spdif output with alsa

Have you read the wiki Alsa topic, specifically the section on SPDIF output?

I've read it and have no clue what to do. My playback switch was already set to true and I never found the second option ac97 playback.

Re: [SOLVED] No sound for optical / spdif output with alsa

Have you tried other device options in .asoundrc? According to the ALSA wiki, the digital device is the one marked IEC958. That would be card 1 device 1.

You might want to read that entire topic in the ALSA wiki if you have not done so already. It has methods for directly testing the digital output using aplay.

Re: [SOLVED] No sound for optical / spdif output with alsa

That worked! Thanks 2ManyDogs.

The corrected .asoundrc:

defaults.pcm.card 1
defaults.pcm.device 1
defaults.ctl.card 1

You're welcome, and thanks for marking it [solved].
