            Bug ID: 103058
           Summary: Bluetooth speaker used the HSP/HFP profile by default
                    rather than the higher-quality A2DP profile
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: misc

Kubuntu 17.04
Pulseaudio 1:10.0-1ubuntu2
Bluetooth device:
https://smile.amazon.com/VicTsing-Wireless-Waterproof-Hands-Free-Speakerphone/dp/B074DX13T1
(identifies itself as "C6" by default)

The above Bluetooth speaker paired and started streaming audio perfectly on my
Kubuntu 17.04 system. But the audio quality was poor, because the default audio
profile was the low-quality HSP/HFP one. When I used pavucontrol to switch it
to the A2DP profile, it sounded perfect.

I don't know enough about Bluetooth to suggest a solution, but this is
definitely an issue. My Mac used the correct profile with no configuration and
sound was perfect with no configuration, but my Linux system didn't, and I had
to start a reddit thread and read a wiki page to learn how to get the device to
produce decent audio. This is a sub-optimal user experience for someone like my
wife or my mother, who would would just assume that it doesn't work and blame
the speaker or the OS.
