I generally use SonoBus with Loopback on macOS to integrate Clarett 8pre and Quad Cortex input devices along with Logic, Transcribe, etc. for remote band rehearsal. Recently I've noticed SonoBus hangs on startup and has to be force quit.
Upon investigation, this seems related to the audio buffer size. If I set the buffer size high, say 320 samples or higher, then SonoBus starts up fine using a Loopback virtual device for input. But as I attempt to lower the audio buffer size, SonoBus will eventually hang on startup and have to restarted. This doesn't happen every time, it seems dependent on what else is going on in the system. The best I seem to be able to get is around 256 samples without frequent hanging on startup.
If I attempt to set the audio buffer size to 128 or lower, SonoBus hangs immediately and does not even take down the buffer size menu.
I found the same issues with using just the Clarett for SonoBus input, except it happens on much lower audio buffer sizes.
I had expected to be able to lower the audio buffer size until I hear clicks and pops - SonoBus use to work this way. But now setting the buffer size too low seems to cause SonoBus to hang immediately, or sometimes hang on startup.
