Leo,

My statement was not quite right. I took the output of the DAC and connected it to the pad with the resistor leading into opamp.
I think the odd ticks I hear every 30 mins maybe oscillations. May need to put in the 150pf cap. I removed c32,33,34,35. The mods I did included
changing resistors to 30K, removing the caps leading into opamp and out of it.
Also put in 1500 and 100uf for c19 and 21. Iam using toslink now.
I may put in the new values for the PLL.

Sounds good enough now so not sure if these mods will be value add.

Regards
Vinod
