Input sample rate related crash on launch with macOS Monterey 12.2.1

[phaseOne]

Hey there, hope you are all well. I've just installed SonoBus, and have unfortunately hit a snag when launching the app. I think I've narrowed down the cause to a mismatch between the sample rate of the input and output device. Lmk if this should actually be filed upstream with JUCE.

Steps to reproduce:

1. Set system input to Logitech HD Pro Webcam C920, or another input that has a max sample rate of 32000 Hz.
2. Set system output to MacBook Pro Speakers (default sample rate of 48000 Hz).
3. Launch SonoBus and observe crash.

Similar crash:

1. Set the system I/O devices to MacBook Pro Microphone and MacBook Pro Speakers.
2. Launch SonoBus.
3. Set SonoBus Output to <<none>>.
4. Set SonoBus Input to Logitech HD Pro Webcam C920.
5. Set SonoBus Output to MacBook Pro Speakers and observe crash.

Workaround:

Set system input and output to devices with matching sample rates, and launch SonoBus. You can then disable the output device and use the input device with limited sample rate, or use another output device that has a sample rate that matches your input.
