[Bug 1199059] Re: A2DP audio sink devices failed to work with "bluetoothd : Unable to select SEP" in system log.


After several hours of googling and trying various suggested fixes, I
have my bluetooth speakers working and have some hints.  Hopefully
package maintainers et al can coax them into a more usable form

First and foremost I found the following two URLs of enormous help:



The real issue was that module-bluetooth-discover was not loading (and
still does not automatically)

Test by:
pactl list | grep -i module-bluetooth-discover

If empty load via
 pactl load-module module-bluetooth-discover

Pulse audio will then (hopefully) recognize the device

The rest is sketchier since I needed to do this the first time, but not
there after

First, pulse audio sees the device in the playback menu, normally where
you see something like "Built-in Audio Duplex ..."

But the first time I tried the instructions in the URL above for
associating the device with a2dp, they  did not work.  Instead, I went
in through the bluetooth widget, selected the device, selected audio
profile and then a2dp.

Then you could select the speakers from the pulse audio control panel

Have no idea how to get the pactl load-module to happen automatically,
except (of course) I will write a script :)

I hope this helps a few ...
