Here¡¯s another thing.? There are other ways to interface USB to the Teensy if you need more USB hardware.? The FT201, FT233, FT311, FT2222 are all devices that sit on one of the I2C busses as a USB translation device.? There appear to be Arduino libraries for all of these devices. ? ? ? Dr. William J.

No cables attached except for Ribbon cables and rf coax. Nothing attached to Audio Hat.
I think I will start on new Main board (don't believe I could get hearers off even with my vacuum sucker) and use machine pin headers.
I used those on critical projects that needed IC's replaced often.

I am going to flat out lie and say I've never missed a pin or soldered it incorrectly.?

I have half a thought that hopefully someone can either finish or explain why it wouldn't help.? I'm trying to think of the easiest way to check the connection of the pins.? I've been lucky so far but I'm sure I'll run into self created issues eventually.? Almost every pin on the teensy is PWM capable.? Does it make sense at all to write a sketch with a tone() function for every PWM pin (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 19, 22, 23, 24, 25, 28, 29, 33, 36, 37, 42, 43, 44, 45, 46, 47, 51, 54) then stick the teensy on a breadboard and connect a speaker it to each pin one at a time until you find the one(s) that stays quiet or something similar with an led?? I'm mostly figuring this out as I go so I may be way off base here.

I actually had to ditch the extension board.? After several intermittent software issues I discovered that by pushing down on the teensy and restarting it would work normally for a while only to happen again. This was after resoldering and checking all pins
on both the extension board and the Teensy.??I came to the conclusion that there were at least a couple of socket pins not making consistent good contact.? Because of my frustration I finally removed the extension board and cut a notch in the one heat sink
that was interfering with the audio hat.? Since doing that I have not had another instance of software intermittently working. I guess putting the regulators on the other side of the board and not modifying the heat sink would have accomplished the same thing.??
