Greetings @spockfish:
I upgraded to the beta release of RoPieeeXL 2024.01.90 (1339) to my Raspberry Pi Zero 2 W successfully, but I still have reduced playback volume in Plexamp. I mentioned this problem here and here. I believe the volume was working correctly in Plexamp for me in build 20230924.1116. Someone mentioned submitting feedback to you, but I was not sure if it was appropriate to submit feedback to you without your consent.
I can also downgrade a previous build and report back to you if it is more helpful to you. If you would like me to downgrade, please let me know which build to install and if I should update you in this thread or elsewhere.
Best regards,
RU
