i bought a meCool km2 android tv box amazon link
it works great transcoding ac-4 to ac-3 to get dolby 5.1 sound, when using the hdhomerun app and their atsc3.0 tuners, with the hdhr audio option set to 'passthrough when possible'.
the problem is i want to use the channels app, not hdhomerun app. but with channels i get no sound.
is there a way you can do the same trick as the hdhr app does to pass ac-4 to the mecool box so it can do its transcode thing?
