System information

Godot v4.5.beta3.mono - Windows 11 (build 26100) - Multi-window, 1 monitor - Vulkan (Forward+) - integrated AMD Radeon(TM) Graphics (Advanced Micro Devices, Inc.; 32.0.11024.2) - AMD Ryzen 7 9700X 8-Core Processor (16 threads) - 31.12 GiB memory

Issue description

Every time Windows wakes up from sleep, I get this error:

  ERROR: drivers/wasapi/audio_driver_wasapi.cpp:774 - WASAPI: GetBufferSize error
  WARNING: drivers/wasapi/audio_driver_wasapi.cpp:845 - WASAPI: Current output_device invalidated, closing output_device

Audio still works fine after this error message.

Steps to reproduce

1. Start Godot editor
2. Put Windows to sleep
3. Wake up --> Error message

My guess is that OnDeviceStateChanged

godot/drivers/wasapi/audio_driver_wasapi.cpp

Line 174 in 2a9ff39

HRESULT STDMETHODCALLTYPE OnDeviceStateChanged(LPCWSTR pwstrDeviceId, DWORD dwNewState) {

could be used to detect when Windows goes to sleep and wakes up. Likely the audio device should be freed when Windows goes to sleep and recreated when Windows wakes up. However, I do not know enough about WASAPI for being able to fix this.
