Public bug reported:

Hissing and high-pitched noises occasionally play through headphones. It
happens as a one-off but happens frequently. Sometimes it happens whilst
playing audio, but sometimes just after audio plays. It's difficult to
reliably reproduce but it happens often.

There is a hack for it which is to go to /etc/pulse/default.pa , comment
out "load-module module-suspend-on-idle" , and then restart pulseaudio .
With this hack I no longer get any hissing or high-pitched noises.
