You might have some more luck asking the Linux Audio Developers mailing list. Try searching through the archives - someone may have asked this before. 2. Look through any ALSA driver documentation - and maybe also the source code for existing drivers. I don't know what software you would like to talk to your soundcard - but ALSA is definitely the currently desired driver. 3. I have no idea what your experience of programming is. Books are always good - try your local bookshops. Hope this helps Michael Nelson
