Some 92HD7xxx codecs have amps on the ports to volume control and/or mute certain ports. Also this makes stac92hd71bxx unmute amps lines in the init not needed.

The patch will create more controls such as "Headphone Gain Playback Control". What would be a benifit to have both "Headphone" and "Headphone Gain" controls? I'd like to avoid redundancy if both provide a similar functionality.
Well as in the 92HD71Bxxx case it would be useless, but for 92HD73xx series where we have two headphone outs which share the same DAC, you could control the gains/mutes for each HP port. Same with the line-outs and speaker outs.
Also, "Line In As Output Gain Playback Volume" is hard to understand. Let's make it simple.
Ok I can see your point here, "Line In As Output Gain Switch" is kinda no not needed now that I think about it(since if you switch a port to output it powers down the in-amp). As for "Line In As Output Gain Playback Volume" it could be changed to "Line In as Output Volume" so that would be part of "Line In as Output" mixer, I think that would be more clear.
thanks,
Takashi
