Thank you Leonid for responding. I gave it a good try again, with trial
and error with all kind of variations of the different asoundrc files I
attached in my previous mails. I am unable to get it working with two
audio streams to one bluetooth devices (mixing).

I ended up with lots of messages like "Unknown field pcm_slave". Could
you please post a complete asoundrc file that has been tested to work
with two speaker-test -c2 programs running beside each other?

Just to be clear, I have no problem getting my bluetooth audio device to
work with single audio streams, I would like to have mixing support
working so I can play multiple audio sources at the same time.

Thanks in advance,

Jelle
