I’m not a native speaker, so if is problem unclear please ask.
Hardware: RPi 3+ B plus HiFiBerry AMP+ (not AMP2) as HAT to RPi.
Software: osmc since Aug 2016 with osmc default skin.
Since the update to latest osmc with MyOSMC Manual Update did not work, the error message was only displayed for a moment and it said something about connection problem, I used SSH from Ubuntu 21.04 Desktop to osmc and initiated the update from the comandline: sudo systemctl start manual-update.
After the update finished and RPi rebooted there was no sound. I found out that the line dtoverlay=hifiberry-amp was neither in /boot/config.txt nor in /boot/config-user.txt.
I suspect the old HiFiBerry amplifier AMP+ is a seldom used piece of hardware and tests during development didn’t show this problem.
I didn’t read the release notes and I can’t find them on osmc.tv. The split of config.txt into 2 files and the Warning at the beginning of the new config.txt file gave a clear message, but I expected the upgrade would move ‘unusual entries’ to config-user.txt. Where can I find the release notes, please send a link.
