⚠️ Classic esp32: audio input not working when using a firmware with HUB75 support #333
Description
What happened?
I2S audio stop working ("silent" or totally noisy) when the firmware has the HUB75 driver included.
Its enough to have the driver present, no matter if a HUB75 panel is actually used.
Workaround: Install a WLEDMM firmware without HUB75 support.
To Reproduce Bug
Install a WLEDMM "HUB75" firmware bin on any classic esp32 that previously had a working I2S audio source (INMP441, ICS4343, PICO board, etc).
Analysis
Suspected root cause: the HUB75 "abuses" the I2S unit of the chip for driving the HUB75 panel. It seems that the driver includes some components that render audio via I2S unusable.
Expected Behavior
dunno.
Install Method
Self-Compiled or other
What version/release of MM WLED?
v14.5.x and v14.7.x with HUB75 support
Which microcontroller/board are you seeing the problem on?
ESP32
Relevant log/trace output
Anything else?
