Can't get volume control of digital out
Hi!
I'm using my computer as a media center and therefore got it connected to my amp through a DAC. I'm using the digital out connection on my soundcard and got a toslink going from the computer to the DAC. The sound is working, but I can't control the volume. Anyone know what I need to do? 
Here's what I get from amixer:

}What's up with all the mono outputs in aplay -l?? My goal is to get raw digital output and let the DAC handle it. What do I need to do?
Thanks to anyone who can help me. This is the final issue to get sorted out before my media center solution is 100%!

Re: Can't get volume control of digital out
I use a coaxial digital output, and the only way for me to adjust the volume on it is the PCM channel.
Yours should be this:
Simple mixer control 'PCM',0In your amixer output.
Hope this helps.

Ah, but it isn't. 
What do I have to do to make it so??
Edit: Well it actually is if you look at the amixer output posted above. But I still can't control the volume of my digital output. 
Anyone?

Re: Can't get volume control of digital out
You can control PCM's volume using alsamixer from alsa-utils package
PCM channel should be there.

I know. But it doesn't affect the digital out volume. I've tried muting/unmuting, +/- every volume option in alsamixer, but nothing affects the digital out volume.
I need to configure one of the config files connected to the sound output so that I can link the PCM volume to the digital volume. I just can't figure out how.
Can you post your asound.state (or .asoundrc) please Setsuna so I can compare it to mine?
Thanks for trying to help me!

Re: Can't get volume control of digital out
I'm testing the volume with mpd/sonata.
When I get this fixed I will be mainly using freevo. Since I'm having problems with the volume I can't use freevo's volume control that I've got mapped to my remote. It's really annoying. When this is out of my way I can do most of what I need from the amazing comfort of my couch.

Re: Can't get volume control of digital out
I'll call it a night. This is really hard to get right.
Seems I need to get a correctly configured .asoundrc
but I'm having trouble doing it. Hopefully someone can help.
Thanks for the help setsuna!!!
I'll get this thing working one way or another!

Re: Can't get volume control of digital out
Exactly, that's why it is called "passthrough". It sends the digital signal as-is and your amp does hardware decoding.
