Audio Tracks with Plex Live TV

Plex Version 1.9.5.4339
Windows 10 Core I7 - This computer is about 5 yrs old so the I7 then is probably comparable to an I3 now.
AVerMedia Volar Hybrid Q tuner.
Amazon Fire TV V1 with current version of Plex.

Issue #1
I know Plex Live TV is a work in progress and it works for the most part with my AVerMedia Volar Hybrid Q Tuner. To get Plex to work wih the AVerMedia tuner, I had to uninstall the software (AVerMedia Center 3D) that came with it and just use the driver files only. The AVerMedia Tuner records programs just fine and the quality is really good. Issue is it also records an audio track (assuming for the blind) that narrates the scene setting. Is there a way to turn this track off or not record It at all?

Issue #2
Also, Live TV works just fine on my Android phone & tablet. On the Fire TV, when trying to tune a channel, I get audio just fine. The picture shows a continuously spinning circle and usually makes Plex restart.

My main focus is fixing Issue #1 more so than Issue #2

Any thoughts?
