I checked in Firefox 55, which routes all audio via PulseAudio, and
sound is perfect.
There may be a problem between chromium-browser and pulseaudio.
** Description changed:
PulseAudio exhibits abnormal behavior after resuming from suspend:
- Crackling sound present during HTML5 video playback in browsers (Chromium,
Firefox, Chrome).
+ Crackling sound present during HTML5 video playback in Chromium 60.
I tried adding tsched=0 to load-module module-udev-detect in
/etc/pulse/default.pa, and it didn't work.
I slightly increased fragment number and size in /etc/pulse/daemon.conf,
didn't work either.
Before suspending, multiple sound sources can be handled without problems nor
audible noise.
After suspending machine, sound source is noisy/crackling, as if there were
buffer underruns.
