Ok, this has been a slight mystery for me for quite a while. Just looking for best practices.
My Rpi3 goes to my TV using HDMI. From the TV to Reciever it uses SPDIF. I don’t like using passthrough because it is always way too loud, and I have to run over to turn it down (I know, I’m lazy). Assume I’m not using passthrough.
I’ve set my audio up for 2.0 as SPDIF can’t handle more than two channels. Ideally, I’d like 5.1. Will it work properly (or distribute the channels) if I choose 5.1? I just use 2.0 because I assume I need to use passthrough to get Dolby Digital 5.1 decoding.
Second question, what is the benefit of using ALSA vs. HDMI as the audio device? I was fiddling around with ALSA (with no luck) to get an equalizer going, but it never worked. Which setting is better, or is there no difference?
I’m pretty sure DSP has not been set up properly or in use for OSMC yet…or they’re planning on removing it.
