It is required to have at least one free channel between channels, to
avoid interferences.
This is only a warning, it will not reject channels next to each other.

Rework on audio buffer management

Use function to get samples to be sent to fill audio buffers to a
level. This replaces the function that only shows how much data
is in the buffer.
This way the function itself can control how much data will be
sent.
