I've installed pulseaudio since bluetooth audio headsets doesn't work
anymore in wheezy without pulseaudio. After this installation I
noticed a crackling sound in some of the stuff I am using. It went
away after I changed the resample-method in /etc/pulse/daemon.conf to
src-sinc-fastest. This was actually more an accident than an intended
way to fix the clicking/crackling sound I had with some
programs/sounds. So I started to search for the problem (just searched
for speex and resampler) and found this bug.

I've applied this patch, changed the resampler in pulseaudio back,
installed my package from libspeexdsp and tested it again. Voila this
patch fixed the problem.

But I am starting to get really frustrated about speex/Debian. Why is
this problem known, a fix known and nobody cares to incorporate this
fix in speex or Debian? Are you happy about throwing other peoples
time away? I know it takes a lot of time and effort to create
something like a Distribution, but knowing about a problem _AND_ the
fix and just don't care about it is just mindblowing.
