Quazimodo, how are you doing with the DAC debug, last round of measurement questions?

Thanks Hugh,
OK I've uploaded a JPeg of the relevant part of the circuit.
I've called it S900_DAC... it's in our photo's section here.
So I am getting around 3volts on pins 14 & 19 of the BA9221 (IC107)
on faulty voice channels.
On good voices there is just millivolts on those pins.
Would you suspect the BA9221....?
Cheers,
TOM
