Cyberbladei1 (trident driver) , but other distros including FC5 are having no 
problem with ZynnAddSubFX with this card. All a bit weird.

The only other thing I can think of is that it's something to do with Selinux, 
as it's the first time I've left it enabled, but doesn't make any sense that 
it would cause problems just with Zyn, and no other music apps.

Thanks for the suggestions.
