| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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, ยต-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: |
