Dnotes.rst2 More Notes on HD-Audio Driver
11 HD-audio is the new standard on-board audio component on modern PCs
12 after AC97. Although Linux has been supporting HD-audio since long
15 This document explains the brief trouble-shooting and debugging
16 methods for the HD-audio hardware.
18 The HD-audio component consists of two parts: the controller chip and
19 the codec chips on the HD-audio bus. Linux provides a single driver
20 for all controllers, snd-hda-intel. Although the driver name contains
21 a word of a well-known hardware vendor, it's not specific to it but for
22 all controller chips by other companies. Since the HD-audio
