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: + http://www.student.informatik.tu-darmstadt.de/~tek/projects/linux.html +or: + http://www.tu-darmstadt.de/~tek01/projects/linux.html + +Bugreports, bugfixes and related questions should be sent via E-Mail to: + tek@rbg.informatik.tu-darmstadt.de + +Thorsten Knabe <tek@rbg.informatik.tu-darmstadt.de> +Christoph Hellwig <hch@infradead.org> + Last modified: 2000/09/20 |
