After the sudden withdrawal of snd970930 I felt compelled to implement auto DMA mode. Thanks to a little bit of luck, things went much better than I expected, and although there are still some improvements that I plan to do, the code appears to work surprisingly better than the previous release, fixing various problems which I was having in the past with the OPTI and the SB16, and in general working better also on the CS42xx An EXPERIMENTAL snap of the new audio driver is at http://www.iet.unipi.it/~luigi/snd971003b.tgz This is mainly intended for those who want to spend some time testing audio apps, stress the driver and send me feedback on what works and what does not. For this reason the kernel is a little bit verbose; don't worry if you see things like "Race!" appearing in the logfile, it is harmless and just serves to flag some events. If you don't have time for such testing, please DON'T download this and wait for a next snapshot in a few days. It is preferable if you have already had experience with previous snaps of my driver, so that would save you some time in the installation (you can replace the snd/ subdirectory with the one in this distribution, and check your version of isa.c against the patch in the README file -- there is a one-line change to isa.c to make isa_dmastart less verbose). I have tested this code, and have it working in full duplex, on CS4236, CS4237, OPTI931, SB16 Vibra16. It _should_ work with the Ensoniq SoundscapeVIVO, Yamaha SA2 (aka YM711), and in general with all WSS clones. It is _NOT_ supposed to work on the SBPro or other SB2/SB3 clones. Cheers Luigi
