Hi there, Is there documentation anywhere that reflects the theory of operation and intended use of the state of the audio drivers in -current? I remember that Cameron Grant (?) had a document with some nice diagrams at about the time that the new PCI framework went in, but I can't find it, now, and I don't know how relevant it still is. I looked at the soundcard.h header last weekend, and started some exploratory coding, using the FreeBSD (as opposed to the OSS) IOCTLs, but wasn't having a whole lot of success. I suspect that part of my problem might be that my sound card, an M-Audio Delta1010 is not actually listed as being supported, but the envy24 driver does seem to recognize it, and it reports the expected number of channels and what-not. I'm confused by the fact that none of the pcm devices that I would expect show up in /dev, and the ones that I used to open when talking to the (then closed-source) oss driver aren't found. Any pointers or suggestions would be most helpful. If I can be of any assistance getting the driver to support the card, then I'll be happy to do that too, if I can. Cheers, -- Andrew
