Patch against SDL 1.2.14

I tracked this down trying to find the cause for crackle in the rear speakers in Nexuiz (with a 6 channel configuration).  Looks like the same problem was described in [1].  Attached is a quick patch that seems to work for me; it simply assumes that the SDL nomenclature is confusing (i.e., says samples, means frames).

Comment 1 Jānis Rūcis 2010-02-11 11:11:31 UTC 
BTW, while the patch probably doesn't apply to 1.3, the report does.
Comment 2 Ryan C. Gordon 2010-02-12 09:14:53 UTC 
This patch is now svn revision #5550 for the 1.2 branch and #5551 for the 1.3 branch.

Thanks!
