Hello everybody,

I have been using some bluetooth stereo a2dp devices, and I would like
get the same usability as with normal connected speaker.

I currently can only play one audio stream, other audio stream can't
connect.

To explain why somebody would like to listen to multiple audio signals
at ones. When playing internet radio or music on my system, I would
still like to be able to listen to second or third audio signals, like
when opening a DVD to check if is working, or to test some media file,
watch an embedded multimedia stream on the internet, like local news
video and audio streams or youtube media and system audio notification.

I this does not convince you that listing to multiple audio streams at
the same time is an useful and wanted feature please tell me why.

So my question is how can I get this functionality on my bluetooth
system? Mabye software mixing is needed, and can somebody help out how
to get this done.

Thank in advance for any help,

Kind regards,

Jelle
