Says guition-esp32-p4-jc4880p443 on the back

P4 CPU (fast CPU)
Plenty of RAM + flash
Speaker and mic built in
tones of ports and extra I/O lines for peripherals

Only issue I have found so far is speaker and mic are on the same bus so it can’t listen for a micro wake word while playing music.

This config has the alexa micro-wake word and the new Sendspin media player preconfigured and enabled.

Does anyone know how to stop the loud pop at the beginning when playing a .mp3. also get a quieter pop at the end of the file. I get the noise even when the speaker volume is set to 0%
