10 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
four input/output DMA engines. For signal levels see the High Definition audio specification (Intel
® ).
