11 Audio Interface
The chipset supports a HD audio codec with 24 bit resolution and 192 kHz sample rate. The interface inclu-
des LINE OUT, LINE IN, MICROPHONE IN and a digital S/PDIF output. The HD audio controller is a bus
mastering PCI device which is physically connected to one or more codecs via the HD audio link. It contains
one or more DMA engines. For signal levels see the High Definition audio specification (Intel
® ).
