Anyone els notice that this DAC still fails the udial clipping test even after correction R35/36

EDIT: measuring from signal pin to ground I get about 3.3-3.4mv (measure on the 200m setting) on the left channel and about 3.7 on the right. |

I hope this doesn't entail having to hunt for issues on the board, and I'm not sure I'm up to mailing this back to Hong Kong. Thanks, Dave |
