Hi,
I moved to Teensy 4.1 after burning my 4.0 with bad power source. I used a new PT8211 card on top of it (scared to re-use old one).
Using the same source code (based on TSynth) as for previous board, the sound generation is ok but every 8 sec there is a beep (like a A 440Hz) occuring for 2 sec and going back to normal sound. It has been same problem for very simple sketch like Guitar or simple fixed waveform but not anymore (???), so I cannot post source code here (too big).
I tried to install the new teensyduino beta version (1.54 beta 5) but didn't change a thing. Here is a link of the output sound.
Does anyone have a guess ? Is it software problem, teensy4.1 or audio board ? Should I change my audio board (I have an audio shield but it is very painfull to unsolder previous one) ?
Thanks for the help.
