Hello all.

Some weeks ago, I asked for a solution to the fact that GUS Classic sound
cards "hanged" on output of digital sound. Somebody (I don't remember) told me
to manually change a line in drivers/sound/dmabuf.c, and it worked OK.

He said his patch were in the way to the source tree, but as of 2.1.111, it
insn't yet. I enclose the patch (although the merit isn't mine), in case
someone found it interesting.

I have 2 computers, one with an AWE64 and the other with a GUS Classic-clone,
and this patch works great on both. Does anybody know if this breaks
something, and where is the problem, then, that the patch solves.
