I'm still on r21577 as this seems the most stable for passtrough, but I want to try PCM for sync reasons but confused:

I have only 2.1 cause no room for 5.1.

1) Is there a difference between kodi channels set to 2.0 & 2.1? my anthem avr just says 2.0 PCM but i'm guessing there is no display for 2.1 PCM.
(when set to 5.1 or 7/1 the avr displays multi pcm 3/2 - 3/4 correctly)

2) what happends to the LFE in dts/dts-hd in pcm ? so when set to 2.0/2.1 does kodi downmix 7.1 to 2 channel stereo & the avr just send the crossover to sub ? problem as in crossover for lfe is higher then normal (and lfe is 10db difference?) ..

3) when speakers set to 7.1 & you play a 5.1 source the avr thinks it's still getting multi pcm 3/4 why doesn't this auto change to what source is, or doesn't this matter ?

Why not set kodi to 5.1 or 7.1 so Kodi only has to decode and not downmix. Then setup the AVR to the appropiate number of speakers, so the AVR handles the mixing stuff.
