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
