Unless otherwise configured module-combine will automatically add all
new hardware sinks to its outputs and drop those which go away. So
this automatism does allow sinks/sources to be added
dynamically/removed dynamically during runtime. However, there is no
user API for that to trigger that in any way but by
unplugging/plugging hardware.
I am using the combiner for up to 3 bluetooth-headsets. But I have
more headsets, so I made a program that waits for bluetooth-signals
of a headset and then loads the headset through the asynchronous
PA-api as module-bluetooth-device. Then I am reloading the
module-combine with a new sink-list. Do you think I can make that
happen automatically without reloading the module-combine?
The streams module-loopback uses you can move around with pavucontrol
or a similar tool.
Can I move it with the asynchronous PA-api? And if yes, how?

Sounds as if there is something wrong with the device speed. which
causes PA to compensate by resampling things.
So would it be possible to fix this? Do you need more info/some logs?
Thanks,
Peter
