STA326

The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital

zero-crossings no clicks will be audible.

The STA326 includes a soft volume algorithm that will step through the intermediate volume

values at a predetermined rate when a volume change occurs. By setting SVE = 0 this can

be bypassed and volume changes will jump from old to new value directly. This feature is

only available if individual channel volume bypass bit is set to 0.
