I think on Proto 0, the only way to enable Audio was to unstuff the SAR sensor. Any time the SAR sensor was stuffed, probing the speaker amplifier failed and audio did not function. So I think we could not help much on Proto 0.

Why do we need to modify the kernel driver on Proto 1 and Proto 2. I can see that the UID and HID has not changed. Also the i2c address has not changed.
