Working on blaster prop and my board just decided to start playing hum audibly at about about 71 minutes of being on.
00:32:48.228 -> Ignition.
...............
01:42:12.470 -> Playing testfont2a/hum01.wav
which sounds possibly related to:
I have my testfont running, and it was sitting on the bench when suddenly I got “hhhuuummmmmmmmm”
Serial monitor shows hum playing all along, as well as swingl and swingh…but they are not audible, even though they are present in the font folder (expected when blaster mode)
I do get preon.wav and out.wav at boot/preset change, but not smoothswings or hum…until this hum thing now.
