@tjaalton and @vicamo, I have tested with 5.15.8 without the headers and the bluetooth device is recognized and appears to work. I again attached a bluetooth headset and listened to audio without issue.
So in summary: FAIL 5.14.0-1013 "No Bluetooth adapters have been found" FAIL 5.14.0-1015 "No Bluetooth adapters have been found" FAIL 5.14.0-1015 without patch (from comment 31) "No Bluetooth adapters have been found" pass 5.14.21-051421-generic Bluetooth adapter available; test audio device works pass 5.15.8-051508-generic Bluetooth adapter available; test audio device works I hope this is helpful, and if there is anything else I can do, please let me know. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.14 in Ubuntu. https://bugs.launchpad.net/bugs/1956393 Title: Bluetooth no longer recognized after update to 5.14.0-1013 Status in linux-oem-5.14 package in Ubuntu: Invalid Status in linux-oem-5.14 source package in Focal: Confirmed Bug description: On Kubuntu Focus computers with the recent update to the OEM 5.14.0-1013 kernel, bluetooth is no longer recognized by KDE Plasma.
