Are you running the 20210104 Android app release?

Nick
No I tested this before that, but will test again when I get home from work. I have updated my device to the newest firmware already though.

Yes I do have audio now on all 4 Denver channels on my X900H now but for some reason the CW is coming through in Spanish.

Edit. Checked again and audio is now English. Big Bang theory was
Playing when it was Spanish.

So I have an odd question. On my Galaxy s20 5G via Emby I can watch Fox 13 direct stream and I have audio and I did confirm its using HEVC. But if I use my Nvidia shield via emby I have no audio. What's the difference? I understand there's no support for ac4 via ffmpeg but why does it work on my Galaxy phone? Thank you!

Media players on Android typically use the builtin decoders on the device first and fall back to software decoders like ffmpeg if there isn't a builtin decoder available. Your phone presumably has a builtin decoder that supports AC-4.

Emby - Yes, this would be FFMpeg failure, just like with Plex on Shield (or anything). For your Shield you should be using the HDHR app for live TV, not Emby as Shield supports AC-4 (though the channel mapping may be off depending on your station). If you are using it for recording, you are stuck with 1.0 channels for now (not that the picture quality is any different).

For the Phone - My Samsung Note 9 is able to play AC-4 in HDHR app so there is no question that S20 has a (probably better) decoder too.

I have three different Android devices that have audio on the atsc 3.0 channels.
Nvidia shield
TiVo stream 4K
Mecool KM1. The Mecool is my player of choice.

Here's another data point... I picked up a LG OLED CX TV this weekend. The WebOS sees the HDHR on my network as a multimedia device. I can stream TV from it and it happily plays the PDX ATSC 3.0 streams with audio and video. Pretty stable as well...

I'm shopping for a tablet for use as a wall panel with home automation. But I'd like to be able to watch shows on it also. What can I get that will support AC-4?

Are you using the HDHomerun app, or just as a UPnP/DNLA media device? Btw, I believe the CX and other 2020 LG OLEDs should have ATSC 3.0 tuners builtin to the TV already. So that is another avenue to tune to the channels if you're so inclined.

The GX has the ATSC 3.0 tuner but not the CX or below.

On the TV I'm not using a HDHomerun app but using the HDHR as a UPnP/DNLA device.

TV is currently only using Android 9 and I have been told that AC-4 will not be possible until the Android 10 update in the future.
FWIW a Samsung Galaxy S9 running Android 10 plays great.
T95mini Android TV box running Android 9 plays with no audio on HEVC channels.
