I digged into this issue and I’ve found the problem.
It seems if you open osxaudiosrc before opening osxaudiosink, when osxaudiosinks starts the AUAudio fails.

To reproduce it systematically I created a simple app with 2 button, to open manually the sink pipeline and the source pipeline and I noticed it everytime I start osxaudiosink before osxaudiosinks.

In case I can add this test app in file bug as attachment. What do you think?

Have you enough indoor do you prefer having a test app?

Thanks
Elio
