This was a major problem in the past, because on Windows you could run as many apps as you wanted and sound played perfectly with every of them (even on cheap or integrated cards), while on OS-es that used OSS... you could run only one app at the time. There are some card that support “Hardware mixing” - this feature means that we are able to send multiple streams directly to the card and its hardware will mix it for as (examples of such cards are: all cards using EMU10k1/10k2 chipset (SB Live! (NOT Live! 7.1),SB Audigy (NOT Audigy SE) or Aureal Vortex), however with newer cards this usually isn't the case – even equipment like Asus Xonar doesn't support hardware mixing and this is rather expensive card (don't know about Creative X-fi though...). That's why software sound daemons and mixers were created (ESD, ARTS and now Pulse Audio), however most of this “mixers” were either abandoned quickly (ESD) or were depended on other things (ARTS depend on KDE) hence they were not usable outside their designed environment, and of course application developers needed to write multiple code implementations for every one of them... that was (and still is in some cases) pain in the butt. That's why ALSA developers created dmix – software mixer, first versions were rather buggy, and required manual edition of some files – but right now dmix is pretty good and for most cards it works “out of the box”. Unfortunately... dmix cannot handle OSS directly (even thou OSS is really “emulated” thought ALSA) so if some app try to use OSS, no other apps will be able to get access to sound device (unless you have card with hardware mixer). In other words – all apps you use should be set to use ALSA and all mixers like Pulse Audio or ARTS should be disabled. Then it should work. Using aoss isn't really a good idea – this wrapper usually doesn't work good with wine and this is yet another abstraction layer (another layer=another problems). I recommend you try fixing ALSA problems (probably something is using your card, and that's why “No sound card found” or similar errors are being shown). -------------- next part -------------- An HTML attachment was scrubbed...
