AC-4 Audio

Local OTA broadcast channels here in in the Houston area recently started in ATSC 3.0 and I was excited until I started having audio problems with conversions. The basic problem is that after conversion there simply is no audio.

It seems as if FFMPEG cannot yet handle the ATSC 3.0 audio which I understand is in AC-4 format.

Is anyone aware of a fix coming or have a workaround?

Is there some way to do a test to simply skip conversion if AC-4 Audio is detected?
