Coreaudio: CPAL silently defaults back to system default when device is available and configured.

This is a bit of a strange one that appears to impact MacOS 15.7.7 (24G720). But we are seeing an issue in 0.17.1 where after selecting and configuring a core audio device (no errors present/handled). The callback is using the system default device without respecting the selected device. We can only seem to reproduce this issue on an M4 mac with that version.
