Hi,
Get it. Basically, 5.1 audio should work. What format are you using for testing the 5.1 audio?
I do not use a specific format for testing; the issue occurs using speaker-test as well as using any application with audio output as for example vlc, rhythmbox or a browser like chromium or firefox.
As mentioned, when configuring the output as digital stereo or 7.1 surround, except for the second issue explained in my first mail (which actually is more annoying) the audio works.
Yes, that's strange. I asked about the format is try to make sure you are using the same format as 7.1. As you are using speaker-test, the format is not the problem.
We tried to reproduce this issue here and unfortunately failed. We can't make the HDMI work through our AV receiver.
I checked your alsa-info.sh output and didn't find the problem.
Regard, Libin
