I didn’t see this reported yet, but I’m having some issues with my Bluetooth headset after this update.
Specifically, after updating to the early-release of Koli, audio doesn’t seem to be forwarded to the headset anymore. It’s worked fine before the update, and I tried restarting the headset and removing & repairing it. It seems to pair just fine, just that audio isn’t played back over it (tried with music player, gallery, web browser). Audio works fine from the internal speakers. I was thinking this might be due to the added firejail sandboxing around the apps, if something went awry with the permissions, but find it a bit odd since audio playback works fine over the built-in speaker with the headset disconnected.
This is SFOS on the Xperia XA2 & connected to Bose QC35 II headsets. Curious if anyone else is having similar problems after the update?
