Linux and S/PDIF audio. - Page 2

post #11 of 53
Okay, your sound card is indeed an ATI card and you have the proper driver loaded, and it has digital output support...

When was the last time you updated the system?
Code:
sudo apt-get update && sudo apt-get upgrade

Also, does Mint use Pulseaudio?

In my experience, the Linux kernel handles NB/SB drivers automagically, so I don't think thats the issue.

Just updated, lol.

Unfortunately It didn't work.

Try ditching ALSA for OSS4. I only say this because OSS4 does one thing automatically, it outputs to all sound outputs. I have my analog and my digital as an option, which I love because I can just mute my headphones and turn on my amp! My amp is always running my digital (optic) as an input source so I don't have to configure anything. Though I have like 6 input sources, I just use DVD1 for optic. =)

[edit] I should say that by default ALSA makes you choose, which I find tedious. I already have to turn the amp on and crap.

I think we should try getting alsa to work before we go swapping sound servers.

OP, post the result of this:
Code:
aplay -l

Getting OSS4 running instead of ALSA might take you half the time and digital out is automatically running. He will have to set up ALSA to do so, either by manually setting it in the .asoundrc or finding a program that will do it.

I admit to knowing nothing about OSS, as I've never had much issue with ALSA [except for a USB headset], but if you think thats a better route, I'm willing to let you drive.

Aha. I think we found the issue.

One more command just to make sure:
Code:
asoundconf list

Essentially, it looks like ALSA is defaulting to the HDMI output from your video card rather than the actual sound card.

What we need to do now is set the actual sound card as the default card and see if that fixes the issue. If it does, we'll create a config file that ALSA will parse every time you start Mint up, setting the actual sound card as the default sound output.

First thing to do, though, is find out what 'asoundconf' sees as the name of the sound cards, then use the same program to define the default card. Then it should just be a matter of unmuting channels.
post #20 of 53
You need to read up on ALSA and how to configure the .asoundrc or whatever the global one is. It's not defaulting to the HDMI, otherwise his analog wouldn't work (from OP). It might not even be the asoundrc, might be something else that needs to be set but I'm betting .asoundrc will fix the problem.

[edit]

making a new post, didn't see there were more pages!
