4.3.4 Audio
The US15W Intel® System Controller Hub supports Intel® High Definition Audio (HDA). The Intel® High Definition
Audio supports up to four audio streams (up to 16 channels each), 32-bit sample depth, and sample rates to 192 KHz.
This allows implementation of a hardware codec on your baseboard for 7.1/5.1 audio systems and SDIF ouput. The
pins for the Intel® High Definition Audio are described in the module connector description.
Warning: Only baseboards with HD Audio codec are supported. AC97 codecs are not compatible to US15W SCH.

device.
