Debugging lack of recorded or LiveTV Audio on a single station in my market

I’ve had similar issues with the audio on DVR recordings.
It only affects channels that are broadcasting two audio tracks and one of the tracks typically has “Descriptive” in the ID tag. Some tracks have a “Spanish Descriptive” ID. Some are “English Descriptive”.
Here is what I’ve been doing to bring the audio recording back.

From your Plex Media Server in a browser:

• Settings
  • Languages
    • Prefer Audio Tracks in “None”
    • Prefer Subtitles in “None”
    • Deselect (Unchecked box) - Automatically select audio and subtitle tracks
      These are to try and force Plex to record all audio tracks available
    • Save Changes
• Manage
  • Live TV & DVR
    - Delete DVR

On the Plex Media Server

• Complete any available updates
• Reboot Plex Media Server

From your Plex Media Server in a browser:

• Manage
  • Live TV & DVR
    • Add DVR(s)
    • Rescan Channels

Go to the Live TV and check all of the channels that have more than one audio track. If any channel is missing some audio track, repeat the check of all of the channels until no audio tracks are missing.

Try the DVR.

Hopefully, Plex will record all available audio streams and you may have to select the English stream if more than one is available and Plex doesn’t choose the one you want.

• Playback Settings
  • Audio Stream
    • If more than one audio stream is available, choose the one you want

The best results that I have found is when I make any changes - updates, add files, delete files, etc., I complete them all at once and then go thru this process completely.

With the Plex update for Ubuntu (Version 1.30.0.6486) the audio issues are worse. As an additional workaround, I’m deleting any programs that have audio issues and are on the DVR schedule to record all episodes. I’m then adding individual episodes back in to the DVR schedule to record single episode recordings. So far, this appears to correct the issue and bring in all the available audio tracks to the recording.
