Perhaps it's related to resampling? Does it happen with all audio files
or only certain ones?

You could try and edit /etc/pulse/daemon.conf and change the
resample-method to e.g. "trivial". If the problem is related to
resampling, this should reduce the CPU burden.

Other than that I'd go for some driver issues as Daniel outlined.
