Got my ProtoDac built. I have sound, but full of distortion. Where do I start?
Thanks!
If distortion is in both channels, the problem is with the I2S lines. The I2S signal is garbled. Reflow the solder to resistors R1-R3. Check the resistance of each of the three paths from module pins 1, 2, 3 to GPIO 35, 12 and 40, respectively. Each should measure about 430R.
