A RealTek ALC883 7.1+2 channel High Definition Audio (HDA) codec on an optional IEI®
AC-KIT-883HD HDA audio kit is connected to a 10-pin onboard audio connector that is
interfaced through the Intel® High Definition Audio serial link to the HDA controller
integrated on the Intel® ICH9DO. The audio connector is shown in Figure 2-9.

NOTE:
If an HDA audio kit is going to be installed on the backplane, the HDA
controller must be enabled in the BIOS settings. To enable the HDA
controller please refer to Section 6.7.2 (the
South Bridge Configuration menu) on page 150.
The ALC883 codec provides 10 DAC channels that simultaneously support 7.1 sound
playback, plus two channels of independent stereo sound output (multiple streaming)
through the front panel stereo output. Flexible mixing, mute, and fine gain control functions
provide a complete integrated audio solution for home entertainment PCs. For more
information please refer to the IEI® AC-KIT-883HD HDA audio kit user manual
(AC-KIT-883HD_UMN_v1.0).
