Hi ferret, > would anyone know how to fix bluetooth connectivity / a2dp issues. A > straight forwards troubleshooting check list would be appreciated. The common cause seems to be some devices have a mixed mode and Linux using the worse quality HSP/HFP by default. Switching the device profile's configuration on Linux to A2DP improves the quality. How to do that seems to vary by distribution, desktop, and bluetooth GUI programs installed. Sound Preferences → Hardware → particular headset → Profile → A2DP might be similar. I couldn't find a command-line way to show and edit a device's profile. Perhaps there isn't one. https://wiki.archlinux.org/index.php/Bluetooth_headset was quite handy. Section 1 covers using bluetoothctl(1) to pair to the device and then says to use pavucontrol to tell PulseAudio it's A2DP. That page also says pacmd(1) can be used to switch to A2DP once the device number is known. https://wiki.archlinux.org/index.php/Bluetooth_headset#Switch_between_HSV_and_A2DP_setting Not having any Bluetooth, I can't experiment to see how to obtain that, but I suspect it's another pacmd invocation. That section also mentions reasons why switching PulseAudio to A2DP might fail; it seems GDM, Gnome's Display Manager that provides the login prompt, might stick its oar in before you log in, causing problems.

Not knowing quite what problem you are having, I can only mention that there is a known problem with bluetooth support on Linux. It appears to only affect certain chipsets and manifests itself as an irritating habit of dropping the connection. We gave up in disgust trying to connect a bluetooth keyboard and a bluetooth mouse to a RaspberryPi 3. Having got the one connected, it dropped out when trying to connect the other and vice-versa. Even when we decided that life was too short and gave up on one of the devices, the other still dropped out if left unattended too long. (This also happens on a W 10 machine, but after a longer delay and can be recovered by hitting the shift key, whereas in Raspbian we had to reconnect.) The problem is in the low-level bluetooth code somewhere, not in the GUI tool provided to make the connections. I tracked it down on a x86 forum, but I can't remember which one. Do these symptoms look anything like yours? -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-11-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
