FS#6911 - AS3514 Volume Increase

Here is my simple patch to do the following:

* Disable the headphone Common Mode buffer (distorts the sound if enabled)
* Disable the headphone amp over-current timeout (defaults to 256ms but now set to 0ms)
* Increase the DAC → Mixer gain

I find now that the sound/volume level is now comparable with the Sandisk firmware but don’t turn it up all the way, -9dB is loud enough for me most of the time ;) (sometimes it gets distorted at higher volumes but is good for those odd low volume songs).

works fine here… doesnt seem to go choppy at > 0dB.. just distorted….
and -45db should be mute, but is just very quiet…
