Need help getting pulseaudio on optical output.
Question: how can I make Pulseaudio use the optical output on my motherboard?
I tried lots of stuff, got pavucontrol (the pulseaudio mixer) to list all the 5.1 channels and even digital output, but it just doesn't seem to be sending anything out on the digital / optical / s/pdif output.
In the pavucontrol I made sure that the audio stream (Amarok) got assigned to the digital output, or even the combined output, but that wasn't the problem obviously.
"alsamixer -c 0" shows me the 5.1 channels and an iec958 channel, which I have unmuted.

And it's kernel 2.6.27.2 on Ubuntu Intrepid (8.10).
I'd really like to keep using Pulseaudio though. In a perfect situation, I'd like to be able to select the channels (digital/analog/both, and the separate channels) an audio stream gets sent to, but that's something for later perhaps, right now I just like to use my new home theater set with the optical connection. :)
If I screwed the configuration up somewhere, please let me know so I can learn from it.
If you need more info, I'd be happy to give it..) |
