I guess the next step would be tracing audio on the wet signal path. that is looking at the output of U10.2 (input to the ADC, should be 0-3.3V output for a -10V to +10V input) and U1.2 (amplified output from the DAC, something similar to the input). if either of those are bonked, and the resistors are definitely correct, I would try swapping out the op-amp in case something goofy happened to it. if that's still no good I would check the DAC side of R8 and R25. Should see 1.65V on R8 and audio centered around 1.65V on R25.
