DUAL VOLUME CONTROL

Setting the DVC register bit causes the volume settings to be applied in pairs. For example, the

DVCF causes the Front-Left channel volume settings to be applied to both the Front-Left and Front-

Right channels from the next audio input sample. No update to the VOL registers is required for DVC

to take effect.
