Volume leveling

Would it be possible to make the volume quieter and louder via Bluetooth?

Since the ESP32 uses the same circuitry for BL and wifi they can’t be used simultaneously

The ESP32-S3 has BLE not BL. Even if it would be sharing the chipset and can not be used in parallel, there is no need for that. WiFi may only be needed for downloading content.

I see no problem implementing that in some way.
