Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Documentation for the AD1816(A) sound driver
|
|
============================================
|
|
|
|
Installation:
|
|
-------------
|
|
|
|
To get your AD1816(A) based sound card work, you'll have to enable support for
|
|
experimental code ("Prompt for development and/or incomplete code/drivers")
|
|
and isapnp ("Plug and Play support", "ISA Plug and Play support"). Enable
|
|
"Sound card support", "OSS modules support" and "Support for AD1816(A) based
|
|
cards (EXPERIMENTAL)" in the sound configuration menu, too. Now build, install
|
|
and reboot the new kernel as usual.
|
|
|
|
Features:
|
|
---------
|
|
|
|
List of features supported by this driver:
|
|
- full-duplex support
|
|
- supported audio formats: unsigned 8bit, signed 16bit little endian,
|
|
signed 16bit big endian, µ-law, A-law
|
|
- supported channels: mono and stereo
|
|
- supported recording sources: Master, CD, Line, Line1, Line2, Mic
|
|
- supports phat 3d stereo circuit (Line 3)
|
|
|
|
|
|
Supported cards:
|
|
----------------
|
|
|
|
The following cards are known to work with this driver:
|
|
- Terratec Base 1
|
|
- Terratec Base 64
|
|
- HP Kayak
|
|
- Acer FX-3D
|
|
- SY-1816
|
|
- Highscreen Sound-Boostar 32 Wave 3D
|
|
- Highscreen Sound-Boostar 16
|
|
- AVM Apex Pro card
|
|
- (Aztech SC-16 3D)
|
|
- (Newcom SC-16 3D)
|
|
- (Terratec EWS64S)
|
|
|
|
Cards listed in brackets are not supported reliable. If you have such a card
|
|
you should add the extra parameter:
|
|
options=1
|
|
when loading the ad1816 module via modprobe.
|
|
|
|
|
|
Troubleshooting:
|
|
----------------
|
|
|
|
First of all you should check, if the driver has been loaded
|
|
properly.
|
|
|
|
If loading of the driver succeeds, but playback/capture fails, check
|
|
if you used the correct values for irq, dma and dma2 when loading the module.
|
|
If one of them is wrong you usually get the following error message:
|
|
|
|
Nov 6 17:06:13 tek01 kernel: Sound: DMA (output) timed out - IRQ/DRQ config error?
|
|
|
|
If playback/capture is too fast or to slow, you should have a look at
|
|
the clock chip of your sound card. The AD1816 was designed for a 33MHz
|
|
oscillator, however most sound card manufacturer use slightly
|
|
different oscillators as they are cheaper than 33MHz oscillators. If
|
|
you have such a card you have to adjust the ad1816_clockfreq parameter
|
|
above. For example: For a card using a 32.875MHz oscillator use
|
|
ad1816_clockfreq=32875 instead of ad1816_clockfreq=33000.
|
|
|
|
|
|
Updates, bugfixes and bugreports:
|
|
--------------------------------
|
|
|
|
As the driver is still experimental and under development, you should
|
|
watch out for updates. Updates of the driver are available on the
|
|
Internet from one of my home pages:
