12.2.6 SPEAKER TO LINE OUT
By default, system PC speaker sounds are provided on both the Multi-I/O connector (J5)
and the audio Line Out jack (J21).
To output system PC speaker sounds through the Multi-I/O connector only, use the BIOS
setup program to disable this option.
The stereo sound path still remains available for multimedia applications.
