I have a bluetooth speaker (http://www.sound2go.net/produkte/bigbass-plus).
In ubuntu 13.10 I could go to the audio settings and choose the bluetooth mode (Telephony - Low Quality, of High Quality).
Like shown on this picture:
In Ubuntu 14.04 the speaker still works, but the sound quality is really bad. Just like it was when the low quality mode was selected in Ubuntu 13.10.
And the option to choose the mode is gone from the sound settings.
Like shown on this picture:
I searched every place I could think of and did not find it elsewhere.
How can I get decent sound quality with my speaker in Ubuntu 14.04?
