The client hangs and crashes when connecting a Bluetooth headset while BizHawk is running.

The client hangs and crashes when connecting a Bluetooth headset while BizHawk is running. It seems like the XAudio2 output provider fails to handle the device change/invalidation gracefully, leading to a SharpGenException.

Repro
Start BizHawk (EmuHawk) using the XAudio2 Sound Output provider.

Load any ROM and start emulation.

Turn on or connect a Bluetooth headset.

Set the Bluetooth headset as the default playback device in Windows (or wait for Windows to switch to it automatically).

BizHawk hangs and displays an error dialog.

Start with BizHawk.Bizware.Audio/XAudio2SoundOutput.cs, especially ResetToDefaultDeviceIfNeeded() at line 125 and CalculateSamplesNeeded() at line 136, then trace the call from Sound.UpdateSound(). Reproduce the device switch with the XAudio2 provider and verify that connecting or selecting a Bluetooth headset no longer hangs or crashes with XAUDIO2_E_DEVICE_INVALIDATED.
