Hi Chuck, Just take a look at my bt848 driver and since the documentation for the chipset is freely available it makes the job a lot easier to understand the driver. With respect to the sound driver you are a lot better off asking in -multimedia and specially Luigi for information on how to interface to his snd driver. From a high level point what you need to know is how to initiate dma to and and from the card and this is usually card or chipset specific in other words the chipset for your sound card should have documentation on how to initiate a dma transfer. And of course the documentation should also state the rest of the usual glue logic on how to set input / output rate, audio format , etc.. For now there are enough low level hardware hackers in -multimedia which should be able to help you.
