Physical channel 31 seems to be working OK today, all the virtuals are there working fine.
Physical channel 24 seems to be about the same as yesterday but the audio seems to be a little lower to me today.

I'm not seeing an differences with firmware 20210118.
Physical channel 31 is still showing the No Data error message on it's virtual channels.
Physical 24 is still having low audio issues, but the video looks OK.

What I meant was that they changed the Firmware beta to be able to ignore the .json file which caused the HDHomeRun app to expect that their should be a .json file to ignore on physical channel 24. I just tried physical channel 24 and the virtual channels are working now although they weren't earlie...

I did try 105.1 & 107.1 before I installed the 151 beta and they worked before the Beta install. Time for another WAG. I'm guessing that the beta firmware just ignores the .json code on 151 and Windows 10 HDHomeRun.exe will not work on the other HEVC channels until Silicon Dust installs an interface...

I installed the 151 beta fix and it does indeed fix the No Data problem with 151. I see both video and Spanish audio.
However.... none of the other HEVC channels work now. Both physical channels 24 & 31 show the No Data error message, except for 151.
How do I go back to the previous firmware?

Firmware Version 20210105 is now available.
Haven't seen any differences between it and previous version.
Still have very low sound on 104.1 and 107.1 with Windows 10 HDHomerun app
On iPad 12.9 Pro (second gen) both 104.1 and 107.1 sound normal.
