Plexmediaserver version 1.31 breaks 6-channel AAC playback on Roku Devices

Server Version#:1.31
Player Version#:All Roku Devices

I installed Plexmediaserver 1.31 on Ubuntu 22.04 yesterday. After installation my Roku Devices including my Roku TV and my Roku Ultra would no longer play videos with 6-channel sound encoded AAC. Stereo AAC videos did not have the problem.

When trying to play these videos, I would see the startup spinner, and after about 10 seconds I get an error banner saying:

 Playback has stopped due to multiple playback errors.
 Please check your connection and try again."

<<< Error message JPEG attached >>>

The error did not occur with my other devices:
Chrome Browser
Chromecast with Google TV
T-Mobile Hub

I reverted back to version 1.30.2 and the problem went away.
