I'm not totally complaining here. I'm saying that a card costing twice
as much does deliver an improvement over a 3Dfx, and thus that the "very
best card for Quake3" would rather be something from nVidia. But I
believe that the bang for the buck of the Voodoo serie is incredibly
good, and this is the card I recommend to people.

Yes, by polling the DSP device with SNDCTL_DSP_GETOSPACE (or maybe also
by using select()/poll() on the device). Thanks to Dave Taylor and Dave

No, very little usage. I'm amazed many up-to-date games still use a
separate sound process.
