Below is a patch from a colleague that fixes this. Is it correct? I see precedent for this sequencing setup in the Speaker PGA setup. However, the datasheet implies (by considering together in the same section) that the Line and Headphone Output PGAs are typically programmed in the same fashion, and they already were in the code. Perhaps the Headphone Output PGA also has an issue and needs similar rework?
They both need a similar change, yes. This is due to an error in an earlier revision of the datasheet which incorrectly listed the PGA enables in the power management registers as being copies of the ouput first stage enables.
