I often have this problem using various sound programs. The problem is that
the kernel needs to allocate memory in a certian region, and if the memory
there is is use by something else, it fails. What I do is run some large
program (netscape works well) to swap out a lot of memory, and then exit the
program, which hopefully frees up the memory address the kernel needs for DMA,
and then try again.
If netscape doesn't swap out enough memory, I use the "swapout" program that
is part of the ftape package. On my system with 80 mb ram, I've had to
swapout as much as 60 MB before I could play sounds. Though normally
"swapout 16" will do the trick.
I really hate this kernel problem. :-(
