I think that clicks/pops could be caused by immature audio drivers. I
used to have clicks (though on a different application, don't remember
which now) with my Intel HDA audio card (with the ALC883 codec if that
matters) but don't have click on my good old Yamaha YMF754-based card.

And I don't get frequent segfaults although it happens from time to
time.

Maybe you could compile your LMMS as a 32-bit application and check if
the problems persist? Use the "-m32" gcc switch to tell it to compile
32-bit object code.

Fedora, and many other 64-bit Linux distributions use a different
approach: /usr/lib contains 32-bit libraries and /usr/lib64 contains
64-bit libraries. Since file names often are the same (e.g. for
example /usr/lib/libX11.so.6.2.0 is a 32-bit library
and /usr/lib64/libX11.so.6.2.0 is a 64-bit library) `lib' cannot be a
symlink to lib64.

I guess you have a "pure" 64-bit distribution which doesn't have
support for running 32-bit Linux binaries, which is unfortunate
because, first, it seems that my above suggestion won't work for you,
and second, you cannot use some (rare, I acknowledge) applications that
are available for i386 only (e.g. Adobe releases only 32-bit flash
plugins which can be used via nspluginwrapper).

I would be very glad if I'm wrong.
