LIPSYNC_DELAY：value is [100,500],default 200。unit：ms。
DELAY：value is [0,500],default 0。unit：ms。
These commands，for both HDMI out audio and line out，the delay will be amount of two commands。
Command 1 adjust device driver buffer，command 2 adjust application buffer，so command 2 is priority for use in setup。

Example：
/ # gbconfig –lipsync-audio-delay=100
/ # gbconfig –show –lipsync-audio-delay
100
/ #gbconfig –audio-delay=100
