Thank you djstx2003 for good explanation!

I guess we need to push Nvidia to fix this bug. Atleast I can live with it for a while and just enable/disable passthrough. But then about the refresh rate, i tried to do this: "refresh Rate to always and to put 3 seconds delay" but didnt help.

Hi

I have a Nvidia Shield from 2015 with the latest updates on it. Yesterday when I change to a new reciever/speakers I run into a issue with both Kodi 17 and SPMC 16.5.5.
What happens is that if I start a movie and want it to have passthrough i have to first disable it and then again enable it to get it working. I didnt have this problem before with old reciever.

I have always followed the recommended settings by SPMC from here: https://github.com/koying/SPMC/wiki/Reco...-Receivers

New reciever is a Denon x1300w.

Anyone got any ideas what I can test to fix this problem? Is there any needed settings for audio Passthrough on Nvidia OS?

my friend you are facing a known Nvidia Shield bug. the problem is that your Denon Avr-X1300W have Hdmi 2.0 / HDCP 2.2 interface.
Refresh rate switching doesn't work if the AVR is HDMI 2.0/HDCP 2.2 and the TV / display is HDMI/HDCP 1.4.
Also HD Passthrough have issues in Kodi 17 and latest Spmc.
To fix HD Passthrough and have audio recognized by Denon Avr you have to use Refresh Rate to always and to put 3 seconds delay in SPMC/KODI settings in Pause during refresh rate.
Now about Refresh rate switching that doesn't work I use A HDFury Integral between Shield and Denon Avr( I have Denon AVR-X4200W).
HDFury Integral is expensive but fixes all HDCP connection problems. You can also use a hdmi splitter switch with HDMI 1.3 compatibility that is cheaper than HDFury Integral.
I hope to make you understand the problem and how to fix.
I have already reported through feedback to Nvidia this problem (Refresh rate switching doesn't work if the AVR is HDMI 2.0/HDCP 2.2 and the TV / display is HDMI/HDCP 1.4)
but until 5.1 Shield firmware no fix for this.
Be well my friend. Spiros.
