This problem started sometime around the release of kernel 5.16, but it now persists under 5.15 and 5.10 as well.
Upon booting the computer, everything works flawlessly. When I put the computer to sleep and later wake it up, however, things start acting strange:
- Bluetooth selector in the System Tray detects no devices. If I switch the speakers off and on again, they connect for a second then disconnect again. After this I am able to connect them via the system tray.
- Unable to select sound output/input via the system tray until Bluetooth speakers are connected. Audio will still play through wired devices.
- Shutting down/rebooting takes 15+ minutes. Several minutes of black screen before message “Failed to unmount /home partition” and a message of systemd.shutdown[1] unable to close modules pulseaudio and alsactl. After about 15 minutes it finally reboots and everything works fine again.
Not sure where to start looking for error logs.
Setup:
Manjaro KDE Plasma, testing branch, kernel 5.16
Lenovo Ideacentre, Ryzen 5 3600, Nvidia GTX 1650
