In the stream state callback, use pa_context_errno() to get the error
code (and then you can use pa_strerror() to convert the error code to a
string). Hopefully the error code will provide some hint. There were no
hints in the server log.

It's normal that the headset sink and source are suspending if there
are no streams connected to them.
