Please describe your issue below:
I’m using 2 different OS’s (Ubuntu, CoreElec) on the same VIM4 and to my surprise the ALSA specifications differ between the two.

My questions:
- Which one should I use in the context of getting out 5.1 via HDMI?
- Can I port the ALSA specifications from the one to the other and how?
