Cannot use steering wheel SRC buttons to control PlexAMP on Android head unit

Server Version#: Version 4.156.0 Linux
Player Version#: 4.12.4

Aftermarket Chinese Android head unit. Android 8 I believe would need to confirm.

The steering wheel SRC buttons for play/pause, next, previous don’t work with Plexamp.

They work with every other media player on the device i.e. Spotify, AIMP, native Music player app, even with media playing in any browser. Just not Plexamp. Need to rely on touching the screen to control Plexamp.

If need logs just let me know how to pull them. Been through a few updates, and updates never get them working.

Would be great if this could be fixed.

Bump so it doesn’t close.
