To install the cable that connects the front panel audio solution to the front panel
audio header, follow these steps:
1.
Observe the precautions in "Before You Begin" on page 23.
2.
Turn off all peripheral devices connected to the computer. Turn off the computer
and disconnect the AC power cord.

NOTE
Some chassis still use a front panel audio solution based on the AC ’97 audio
specification. Refer to Table 5 below to connect an AC ’97 front panel solution to the
front panel audio header on the board. The front panel audio jacks will need to be
manually configured for microphone or line out functionality in the Intel
®
Audio Studio
application.
