Re: No Audio V12 troubleshooting

 

When I first built my Main Board, there was no audio. Bad solder
joint(s).
I put the board under a microscope and teased the pins of the DAC chip
with
an Xacto knife. If they moved, they weren't soldered. I also had a few
Teensy pins that weren't soldered.

I looked at pin 24 on Tweensy, Daudio-Out that goes to U5 audio
processor.
There is a signal there but it does not look any thing like a digital
signal, I do see an occasional spike that coinsides with pulse I hear
in headphones.
Anyone ever looked at the D-Audio output from Tweensy with a scope to
see what it looks like?
