I have one of those bluetooth stereo speaker boxes that I use with the <br>
system sometimes. It can be used as a speaker that works with a phone, <br>
or with the computer or phone. The problem is that when I boot the <br>
machine and try to connect to those speakers, it connects using one of <br>
the codecs that's meant to be used with a phone. In that mode, the <br>
sound is mono and sounds like it's being played back over a phone. <br>
Obviously not desirable for listening to music. When I open <br>
blueman-manager, the following audio profiles are available:<br>
<br>
off<br>
headset head unit (HSP/HFP)<br>
Headset Head Unit (HSP/HFP, codec CVSD)<br>
Headset Head Unit (HSP/HFP, codec mSBC)<br>
<br>
After I go through the procedure I've worked out, it connects in high <br>
fidelity mode with the following options available under audio profile <br>
in blueman-manager. The X is next to the one it's using.<br>
<br>
off<br>
headset head unit (HSP/HFP)<br>
High Fidelity Playback (A2DP Sink Codec SBC)<br>
X High Fidelity Playback (A2DP Sink Codec SBC SBC-XQ)<br>
Headset Head Unit (HSP/HFP, codec CVSD)<br>
Headset Head Unit (HSP/HFP, codec mSBC)<br>
<br>
Here's what I have to do to use the high fidelity mode.<br>
<br>
Unplug the bluetooth dongle<br>
Restart bluetooth<br>
Plug in dongle<br>
Launch blueman manager then search for speaker, then connect to it.<br>
<br>
The problem isn't limited to one bluetooth dongle or the speakers I <br>
have. I've used other bluetooth dongles and other speakers but the <br>
problem still persists.<br>
<br>
Here's what hciconfig shows.<br>

<br>
Is there some way I can fix this. If I can't get this fixed, <br>
eventually I'll get an FM transmitter good for covering the yard, plug <br>
it into the system and take a radio outside.<br>
<br>
<br>
Thanks to anyone that can help me get this fixed.<br>
