A CIS can be bi-dirctional, but an audio stream is not. We want to be able to use the same CIS for both an IN stream and an OUT stream.

An audio stream is always either IN or OUT, but a client may setup a single bidirectional CIS for both an IN and an OUT audio stream. We will need some way of coupling such streams.

E.g.

  • a function to pair two streams, giving them a reference to each other
  • currently: audio streams have a CIS, change to having a reference to a CIS

Depends on #41194
