Comment 11 for bug 134297

Michael, you are a really good bug reporter :) I wish I have all bugs fixed this way.

So, your headset is working. It's true that virtual alsa devices are not visible with "aplay -l".
This is not a bug. You have to known how you name your device (default: a2dpd).

I have 2-3 second delay with start/stop. It probably depends on hardware (typical l2ping to my headset is about 40ms) and its ability to create/destroy sessions in fast way. Also you may try to disable debug (in ~/.a2dprc). But tu be sure with this we should ask upstream.

I will update README.Debian in my next upload.
