Just as one data point, I’m not hearing any noise with:
- Windows 10, default format (in the audio device properties) set to 24 bit / 48kHz.
- application is requesting 16-bit, 44.1kHz from SDL. SDL is using the WASAPI backend.
The application is quakespasm and we’re providing audio data via the thread callback method, and not using SDL_mixer or SDL_AudioCVT.
What formats are your OS and SDL app using? Using SDL_mixer?
