Go read post #2 again.
Would the Rpi 4B (at least 2G) be able to do the following 2 things:
1. Play 2160p h265 10 bit HDR files from local/nas source with DTS-HD/Atmos audio passthrough to a compatible soundbar/AVR
2. Stream 4k netflix with atmos soundtracks using the netflix plugin in kodi
I currently have a firestick 4k which can do no2 but not no1. From the reading I've done here it seems that the pi can do no1 but I can't seem to find a definitive answer for no2.
