I'm a long time Kodi user, but no under the hood kinda guy and am at a loss. All of a sudden, Kodi 17.3 will only output 2 channel PCM audio to the receiver. Both my Denon AVR-2805 and my 2.7 i7 Mac Mini running OS 10.12.6 are working just fine and I can get 5.1 sound with VLC and other sources. I'm sure I have no hardware issues with the Mac or my receiver. It's only Kodi that won't output multichannel sound to my receiver regardless of what settings I try. The link to a debugging log is with the passthrough setting on, which I hopefully did correctly. Can anyone see what's going on? I'd sure appreciate some help, because I"ve exhausted my bag of tricks. I'm at the mercy of the kindness of strangers.

It's hard to tell anything as you have chopped so much out of the log.

Please post the full, unmodified log.

Will do. How long should I let the debugging mode go on for?

Here's a much longer, fully complete log:

Thanks for helping.

Disable pass through and set number of channels to 5.1 - does that help?

[JoeBlowinski]

Using the Expert Setting: System>Audio and turning off passthrough, I don't see any place where one can set the number of channels. I know we used to be able to do that, but those options don't appear regardless of whether I chose Optimize, Best Match or Fixed. I've looked around the other setting panels and can't find anyplace where I can set 5.1. Please let me know where those setting have moved to.

In any case, choosing any of the three options of Optimize, Fixed or Best Match with passthrough off makes no difference. I only get two channel PCM. Looking at the audio settings while a movie is playing, I can see that Kodi is seeing multichannel soundtracks, but they are greyed out and can not be selected. Are there any sound preference files I can trash? I can't find any.

Thanks for your help.

I just tried starting over by trashing the Kodi folder in the Applications Support folder in my home library. It still only outputs two channels. Just to make sure, I test played the same movie in VLC and got DTS 5.1. After years of XBMC and Kodi use, I'm bumming out.

Your hdmi device only announces 2 channels.

What exactly is your audio setup and which devices are involved?

Last idea - enable pass through again and ensure that "sync to display" is turned off in video player settings
