WAV Files played to Android Pixel 7 with Plex App

Server Version#: 4.87.2
Player Version#: 9.14.0.37895 (84caac7b)

I have the latest Docker running on Debian 11, and my Plex server is running with the latest plexinc/plex-docker image. I have a Google Nest network setup in Bridge Mode. My service has Remote Access enabled.

I’m using a Pixel 7 with the Plex App to stream my WAV files from a ripped CD. The metadata is read correctly and it shows up in the App as expected. My issue is during playback, my Source isn’t “Direct” as expected, it’s “Transcode” (PCM - OPUS), and the Quality is downgraded to 128 kbps, with a Transcode Reason of “Bitrate exceeds maximum allowed”. The Player is “TREBLE”.

I’ve gone through a lot of user submitted articles saying to adjust the Upload speeds (among other things) which I’ve done to no avail. I was wondering if there might be an issue in the Docker Network layer that could cause this, or maybe my Google Nest setup? I could try FLAC as well, but I like the raw WAV content.

May thanks for any suggestions!

This is usually caused by an indirect connection between server and client.
If I had to guess, it’s an additional NAT introduced by your container.

Flac is a lossless compression. If you play it, you will get the same bit-perfect reproduction as if you played the WAV version.
Plex cannot read metadata from WAV files.
