Description of problem: Bluetooth is no longer working when trying to connect to vehicle head unit. This used to work but now does not. I am not sure which update broke this functionality, but I run updates regularly and noticed the issue mid-March 2016. Devices in question are: Lenovo X220 laptop. This has a USB connected BT controller (output from dmesg): [ 5.618077] usb 1-1.4: New USB device found, idVendor=0a5c, idProduct=217f [ 5.618095] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 5.618099] usb 1-1.4: Product: Broadcom Bluetooth Device [ 5.618102] usb 1-1.4: Manufacturer: Broadcom Corp [ 5.618105] usb 1-1.4: SerialNumber: CC52AFE3D686 Alpine IVE-530BT head unit. Have tried to un-pair/re-pair without success. The laptop and head unit can pair afresh, but no audio output is possible. The following messages were noticed in /var/log/messages. On connection: pulseaudio[3396]: [pulseaudio] module-bluez5-device.c: Profile has no transport On opening 'Sound' control panel selecting 'Alpine AV Receiver' that is connected according to 'Bluetoohth' control panel: pulseaudio[3396]: [pulseaudio] module-bluez5-device.c: Refused to switch profile to headset_head_unit: Not connected Version-Release number of selected component (if applicable): Linux x220 4.4.5-300.fc23.x86_64 #1 SMP Thu Mar 10 17:54:44 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux pulseaudio-libs-glib2-7.1-1.fc23.x86_64 pulseaudio-7.1-1.fc23.x86_64 pulseaudio-module-bluetooth-7.1-1.fc23.x86_64 alsa-plugins-pulseaudio-1.0.29-2.fc23.x86_64 pulseaudio-gdm-hooks-7.1-1.fc23.x86_64 pulseaudio-utils-7.1-1.fc23.x86_64 pulseaudio-libs-7.1-1.fc23.x86_64 pulseaudio-module-x11-7.1-1.fc23.x86_64 How reproducible: 100% Steps to Reproduce: 1. Pair via bluetooth Linux machine with vehicle head unit 2. In 'Sounds' control panel select head unit name to attempt to divert audio out to unit. Actual results: The 'Profile' drop down remains unchanged and shows built in audio profiles Expected results: 'Profile' drop down should change to show headset or A2DP, etc. Additional info: Recently (as of mid-March 2016) broken. This pairing and audio used to work. Other devices that are not head units still work. Ie. Jawbone Jambox was tested perfectly.
