Assistance with CPS3 mobo with no sound

Depends what else uses that 42.9545mhz clock signal if that was defective would the board even function? the clock from the PPU is a derivative of that main clock, so is the 42 mhz clock going in and the actual 14 mhz clock coming out?
I haven't looked into it too much more as fortunately I don't have this problem but perhaps you could fit an external counter to the 42 mhz oscillator output and derive that 14 mhz clock externally (from the PPU) and then feed that into the DAC clock circuit. I dunno just spit balling.
