The Roku Ultra latest release I recently got still doesn't and neither does the Roku built-in to my TCL 65 825 TV. So something by somebody got a update that makes the earlier Shields work recently.
So finally one of my media players works :D
Last I checked a day or two ago it did not work but I think every one that cares is working to add support for ac4 audio and other new codecs coming online with 4k TVs and movies so hopefully more platforms that are popular enough with get it soon. I haven't poked around here much today to see if Silicon Dust added it or Google did it but definitely happy because now I have a way to watch 4k OTA TV with my new tuner if Portland finally actually does 4k soon rather than testing it with regular HD content right now.
Is your Nvedia shield connected to an Atmos sound system? Do you know for sure your shield is mapping the audio channels correctly? My Nvedia shield pro (2020) crashes on channels 8.1 an 12.1 usually within 1 minute. Other channels work fine. Nvidia Shield Pro does not crash when using the Channels app instead of the HDhomerun app on the same channels. AppleTV4k does not crash at all.
My Shield is hooked to a Vizio 42" 5.1 soundbar and it didn't get audio on the 3.0 channels till I posted. It may support Atmos and I'm not sure if my old but new to me Denon 4310ci does as I mainly play audio through the soundbar fed from the hdmi port of the TCL TV.
Ok I just tried everything and the audio works on the soundbar and the Denon no matter what channel I play. The 1.0 channels have proper audio mapping, the 3.0 channels it's left or mostly center channel centered. It reboots occasionally and audio drops occasionally on the 3.0 stuff, might be signal strength, who knows.
A early test recording from the 10 pbs 3.0 channel doesn't play audio or video right now but old 1.0 recordings still play fine.
Such fun beta testing new toys. I have a developer model if it helps anyone.
