==Features==
The Intel High Definition Audio specification includes the following features:<ref name=spec>{{cite web|title=High Definition Audio Specification 1.0a|url=http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/high-definition-audio-specification.pdf|publisher=Intel Corporation|page=17|year=2010}}</ref>

* Up to 15 [[Input device|input]] and 15 [[Output device|output]] streams
* Up to 16 [[PCM]] audio channels per stream
* [[Sampling_(signal_processing)#Bit_depth|Sample resolutions]] of 8, 16, 20, 24 and 32 bits
* [[Sampling (signal processing)#Sampling rate|Sample rates]] of 6–192&nbsp;kHz, and with vendor drivers, up to 384 kHz is possible
* Support for audio [[codec]]s (e.g., [[Analog-to-digital converter|ADC]], [[Digital-to-analog converter|DAC]], [[digital signal processor|DSP]]), [[modem]] codecs, and vendor-offered codecs
* Discoverable codec architecture
* Fine-grained codec power-control
* [[Audio jack]] detection, sensing, and retasking
* Support for [[digital audio]] output, such as [[HDMI]] and [[S/PDIF]], and the actual [[Digital-to-analog converter|DAC]] operations are happen on digital audio devices such as HDMI-based TVs and monitors<ref>https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/high-definition-audio-hd-audio-specification-document.pdf</ref>
* Vendor-offered (OEM or IHV) audio enhancement features 

[[Motherboard]]s typically do not have any more than eight built-in output channels (7.1 surround sound) and four input channels (back and front panel microphone inputs, and a back-panel stereo line-in). Users requiring more audio [[I/O]]s will typically opt for a [[sound card]] or an external [[Digital audio#Interfaces|audio interface]], as these provide additional features that are more oriented towards professional audio applications.
