Hello,
Client had yogurt spilled on left side of MacBook, Speakers stopped working. We have replaced the speakers, still no sound. Can you please direct me to the parts I should be testing for a possible short? Thanks.

Check first SPKRAMP_RESET_L voltage and diode mode.

Do you get headphones sound?

Take a look at U6400/20/60 area.
Compare diode mode readings around them with right side (U6500/20/60).
