Hi, I had a look at snd_uaudio and there I don't find the info I look for.
What I want to do is to have 6 chanel (5.1) SPDIF output. What I don't understand is how to select the connectors. To my understanding the soundsystem only sees a line out and a line in, but not all the other connectors. Looking at the output of sysctl (dev.pcm, dev.uaudio and hw.snd) doesn't give me a hint either.
