I am having problems getting a Creative (not clone) PnP SB16 to work with with either the Voxware snd or Luigi Rizzo's pcm drivers (with the pnp driver defined in both cases). The machine _does_ have a PnP BIOS (from Award). Using the pcm driver, the card is correctly detected and initialised using the same IO/IRQ/DRQ values as Win'95 reports. Only problem is that no audio comes out :-(. Using xanim, I do get a noise which can be varied with the volume control. I also get lots of "WARNING: rdintr but read DMA inactive!" messages. Using the snd driver, I can get mxv to plau .au files, but xanim is still not behaving. And the sbxvi will not configure. I believe that the problem is caused by the DRQs selected by the SB16: 1 and 3. The IO addresses and IRQs appear sensible. On pre-PnP ISA machines, DRQs 0 to 3 are 8-bit and DRQs 4-7 are 16-bit. The (pre-PnP) SB16 needs both an 8-bit and 16-bit DRQ. I would assume that these statements are also true for PnP machines and cards. Both the snd and pcm drivers are full of code which assumes that one DRQ is <4 and the other is >= 4. I've tried using the Win'95 control panel to manually select what I believe to be sensible DRQs (eg 1 and 5), but it only allows a range of 0..3. The soundcard does appear to work under Win'95 (I haven't checked all the features). I've tried looking through the FAQs, handbook, `The Complete FreeBSD', and the mailing list archives to no avail. Can anyone offer any suggestions.
