Board 1

Issues … sounds played from the SD card are garbage. With SD card removed, board warnings play fine
Standard stable 4.7 flash & standard font pack that I always use.
Have tried
- new speaker
- board reflash
- board reformat & new files
- new SD card
- Board voltage is fine
This file is a standard Teensy Soundfont bootup. Instead of tenths of a sec… it just drraaaaggggggssss out.
Board 2
I replaced the board. Same issue. Only common parts were SD Card, speaker (tested 8 ohm), RCP (RCP tested OK).
Serial monitor:
4.09 with battery connected
2.03 on USB only, settling to 1.98v
I’ve noted a test of the 5V pin is prudent. I’m only getting 0.87v on the 5v pin with the cell hooked up. 0.96v on the 5v pin just on USB.
