3 | * Apple Onboard Audio driver for Onyx codec | |
4 | * | |
5 | * Copyright 2006 Johannes Berg <johannes@sipsolutions.net> | |
6 | * | |
f3d9478b JB |
7 | * This is a driver for the pcm3052 codec chip (codenamed Onyx) |
8 | * that is present in newer Apple hardware (with digital output). | |
9 | * | |
10 | * The Onyx codec has the following connections (listed by the bit | |
11 | * to be used in aoa_codec.connected): | |
12 | * 0: analog output | |
13 | * 1: digital output | |
14 | * 2: line input | |
15 | * 3: microphone input | |
16 | * Note that even though I know of no machine that has for example | |
17 | * the digital output connected but not the analog, I have handled | |
18 | * all the different cases in the code so that this driver may serve | |
19 | * as a good example of what to do. | |
20 | * | |
21 | * NOTE: This driver assumes that there's at most one chip to be | |
22 | * used with one alsa card, in form of creating all kinds | |
23 | * of mixer elements without regard for their existence. | |
24 | * But snd-aoa assumes that there's at most one card, so | |
25 | * this means you can only have one onyx on a system. This | |
26 | * should probably be fixed by changing the assumption of | |
27 | * having just a single card on a system, and making the | |
28 | * 'card' pointer accessible to anyone who needs it instead | |
29 | * of hiding it in the aoa_snd_* functions... | |
