Default Re: Old Gateway 2000 speakers out of sorts.

Per your readings in post #48
Pin 2: Bootstrap 2 reported as:14.5
Pin 6: Bootstrap 1 reported as: 0.46. This one looks bad. You may want to check that cap between pin 5 and pin 6.

Pin 3: Output 2 reported as:0.5
Pin 5: Output 1 reported as: 0.5
I expect them to be like that, 0.50V, if pin 8 VCC 2 Voltage is not present when headphone is plugged in, but you have VCC2 on pin 8 of the IC.
I guess you can try new TA chip.
