This probably happens, because pulseaudio consumes more CPU time in a
realtime thread than the kernel allows. To work around this problem,
you can disable realtime scheduling with this option in

realtime-scheduling = no

As an alternative, you can also try reducing the buffer size (smaller
buffer means that pulseaudio processes audio more often, but spends
less time each time). Pass the "tsched_buffer_size" argument to module-
udev-detect in /etc/pulse/default.pa. For example:

load-module module-udev-detect tsched_buffer_size=50000

The buffer size is in bytes. 50000 bytes corresponds to about 283
milliseconds with a typical audio format.
