System headphone output changes to mono when Simulator is running

[matt (gingerbeardman)]

(not sure if this is specific to my setup)

1. Use Bluetooth headphones
2. Listen to music eg, Apple Music on macOS
3. Run Simulator

Expected

• no change to audio

Actual

1. as Simulator launches: audio dips
2. when audio comes back it is mono, lower quality
3. quit Simulator
4. as Simulator quits: audio dips
5. when audio comes back it is stereo, full quality

This seems to have been a side effect of my input being set to Bluetooth mic.

I could also get the change to mono to happen by doing a screen recording with mic input audio, so not involving any Playdate SDK software at all.

I guess when the Simulator launches it somehow triggers mic input permissions?

Workaround

• set input to computer built-in mic
