The biggest changes in the new SDL snapshots are DMA audio support under
Linux, and the initial cut of audio support on MacOS thanks to Darrel
Walisser. The DMA code noticeably reduces the latency of the Linux audio,
and getting any sound out of the Mac is, to me, amazing!
I’ve been trying to set up sound on my Linux box for ages. I have a Maxisound
Home Studio Pro 64. Does the DMA routines call the sound drivers or will it
work on an unconfigured card? Oh man, this is such a stupid question…

No, it still requires a normally working sound card. And I think some
cards don’t support DMA (but I guess this fail overs nicely to regular
non-DMA sound).
DMA is used by mmapp()ing the /dev/dsp device (this being a
programming-related discussion group that you either know what is mmap()
or are able to find out by Reading The Fine Manual), so the /dev/dsp
device has to work in the first place.–

It uses the OSS API, so yes, it has to be configured with a sound driver.
