1 | Documentation for the AD1816(A) sound driver | ||
2 | ============================================ | ||
3 | |||
4 | Installation: | ||
5 | ------------- | ||
6 | |||
7 | To get your AD1816(A) based sound card work, you'll have to enable support for | ||
8 | experimental code ("Prompt for development and/or incomplete code/drivers") | ||
9 | and isapnp ("Plug and Play support", "ISA Plug and Play support"). Enable | ||
10 | "Sound card support", "OSS modules support" and "Support for AD1816(A) based | ||
11 | cards (EXPERIMENTAL)" in the sound configuration menu, too. Now build, install | ||
12 | and reboot the new kernel as usual. | ||
13 | |||
14 | Features: | ||
15 | --------- | ||
16 | |||
17 | List of features supported by this driver: | ||
18 | - full-duplex support | ||
19 | - supported audio formats: unsigned 8bit, signed 16bit little endian, | ||
20 | signed 16bit big endian, µ-law, A-law | ||
21 | - supported channels: mono and stereo | ||
22 | - supported recording sources: Master, CD, Line, Line1, Line2, Mic | ||
23 | - supports phat 3d stereo circuit (Line 3) | ||
24 | |||
25 | |||
26 | Supported cards: | ||
27 | ---------------- | ||
28 | |||
29 | The following cards are known to work with this driver: | ||
30 | - Terratec Base 1 | ||
31 | - Terratec Base 64 | ||
32 | - HP Kayak | ||
33 | - Acer FX-3D | ||
34 | - SY-1816 | ||
35 | - Highscreen Sound-Boostar 32 Wave 3D | ||
36 | - Highscreen Sound-Boostar 16 | ||
37 | - AVM Apex Pro card | ||
38 | - (Aztech SC-16 3D) | ||
39 | - (Newcom SC-16 3D) | ||
40 | - (Terratec EWS64S) | ||
41 | |||
42 | Cards listed in brackets are not supported reliable. If you have such a card | ||
43 | you should add the extra parameter: | ||
44 | options=1 | ||
45 | when loading the ad1816 module via modprobe. | ||
46 | |||
47 | |||
48 | Troubleshooting: | ||
49 | ---------------- | ||
50 | |||
51 | First of all you should check, if the driver has been loaded | ||
52 | properly. | ||
53 | |||
54 | If loading of the driver succeeds, but playback/capture fails, check | ||
55 | if you used the correct values for irq, dma and dma2 when loading the module. | ||
56 | If one of them is wrong you usually get the following error message: | ||
57 | |||
58 | Nov 6 17:06:13 tek01 kernel: Sound: DMA (output) timed out - IRQ/DRQ config error? | ||
59 | |||
60 | If playback/capture is too fast or to slow, you should have a look at | ||
61 | the clock chip of your sound card. The AD1816 was designed for a 33MHz | ||
62 | oscillator, however most sound card manufacturer use slightly | ||
63 | different oscillators as they are cheaper than 33MHz oscillators. If | ||
64 | you have such a card you have to adjust the ad1816_clockfreq parameter | ||
65 | above. For example: For a card using a 32.875MHz oscillator use | ||
66 | ad1816_clockfreq=32875 instead of ad1816_clockfreq=33000. | ||
67 | |||
68 | |||
69 | Updates, bugfixes and bugreports: | ||
70 | -------------------------------- | ||
71 | |||
72 | As the driver is still experimental and under development, you should | ||
73 | watch out for updates. Updates of the driver are available on the | ||
74 | Internet from one of my home pages: | ||
75 | http://www.student.informatik.tu-darmstadt.de/~tek/projects/linux.html | ||
76 | or: | ||
