sound sources. If you use 2-channel speaker, only Front Left and Front Right
bars are available for you to configure. If you use 4-channel speaker, only
Front Left, Front Right, Rear Left and Rear Right bars are available. In 6-channel
mode, you may adjust all the speakers as showed above.
h Loudness (AGC): Loudness w/Auto-Gain-Control: When you want a higher
volume level of digital audio, you can enable Loudness (AGC). It provides
extra +3dB to +12dB gain to all channels. The driver has also been designed
with a sophisticated auto gain control minimizing the signal clipping
distortion. However, it is not recommended to

best sound quality. The best way is to increase the
volume of external speakers or just to increase the
Master Volume in Microsoft Volume Control.
