If it is sending 2 dead channels then the receiver will not try to matrix the surround channels to the back. My Denon shows at all times it is getting a 7.1 signal from Kodi.
Now if setting Kodi to "optimized" doesn't alter the uncompressed audio then that's the solution. Is that the solution?
Hi drhill:
I have Kodi set to "optimized".
Given that I get these readings from the audio input status of my Denon when # of channels is set to 7.1 in Kodi 16:
BB= 3/2/.1
AOU=3/4/.1
SA=3/4/.1
It's fair to conclude that Kodi is not sending me two empty channels on 5.1 source material, so me personally I would not set it to "fixed" because Kodi is always going to force a 7.1 channel output regardless of the source (and force it to the selected sampling rate). I want Kodi to send the unaltered, decoded source to my Denon.
So after giving it some thought & re-reading the descriptions, I'm going to set my channel configuration to 7.1 because I have blu ray rips that are 7.1 DTS-MA & True HD.
Output configuration to "optimized" as the properties of the source material is set at the start of playback, and TBH, I've never seen the audio format change in the middle of a ripped movie.
However, I'm guessing "Best Match" would work as well since it changes if the source properties change....this is probably a good choice for playing a blu ray disc as the audio properties will change playing menus, intros, etc.
...and I'm going to assume that when my Denon gets a PCM 3/4/.1 input it folds those 4 surround channels into 2 as I only have a 5.1 speaker set up.
For me, that's the real question in my circumstances.
Full disclosure, I'm certainly no expert & don't claim to be. I'm making this up as I go along.
