Sure. If the code responsible for filling audio buffers never gets
scheduled on the CPU, then those audio buffers will contain garbage and
you'll get stutter.

It's puzzling that Macs whose audio playback you rely on are exposed to
a network where they can be directly targeted for SSH bruteforce. If
these are workstations, best practice would likely be to place them
behind a firewall. If remote access is necessary, a VPN seems
appropriate.
