It seems that some AS3514 registers are never initialized. Currently, the code apparently seems to rely on power-up defaults, but I think it is better to explicitly initialize those registers.

The initialization values in this patch shut down the speaker stage as much as possible, possibly resulting in reduced power consumption. We don't need the speaker output, because all sound is produced through the headphones.

This was tested on a Sansa e260.
This task depends upon
