Public bug reported: Since upgrading from 14.10 to 15.04 and then 15.10, my Bluetooth is buggy (e.g., it does not automatically connect to my headphone, needs manual "turning on" in the indicator applet and some good luck to do this).
My bluetooth device is # lsusb | grep Blue Bus 004 Device 014: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0 I think this device should be handled by ath3k.ko: # modinfo /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko| grep 3004 alias: usb:v0CF3p3004d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v04CAp3004d*dc*dsc*dp*ic*isc*ip*in* # uname -r 4.2.0-18-generic Indeed, ath3k.ko is loaded # lsmod | grep 'ath3k\|btusb' ath3k 20480 0 btusb 45056 0 btrtl 16384 1 btusb btbcm 16384 1 btusb btintel 16384 1 btusb bluetooth 516096 48 bnep,ath3k,btbcm,btrtl,btusb,rfcomm,btintel However, if I remove ath3k, bluetooth keeps streaming sound to my headphone: # modprobe -r ath3k [noting happens] while, if I remove the generic module # modprobe -r btusb the entire bluetooth architechture breaks down, my headphone goes silent, and sound now comes out of the built-in speakers. I'd hope that if ath3k was actually used, my bluetooth would be less buggy. What can I do?
