Thank you for your bug report, could you try if adding that option to the kernel boot line helps? snd_hda_intel.power_save=0 (https://askubuntu.com/questions/19486/how-do-i-add-a-kernel-boot-parameter/19487 has tip on how to do that if you need directions)

Any time a sound plays, whether it's from a browser (both Firefox and Chromium), Slack, video or MP3 file, sound in VirtualBox OS, etc. Any sound, even an alert sound or even just opening an app that may make a sound (e.g. opening a browser page that may have alerts or sounds (like a game) makes the same popping sound just when browsing to that page). It's preceded by a pop or a click from the speakers, a fast pop-pop sound. When said audio is finished, about 25% of the time there is another audible pop or click. I have 18.04.x LTS on another hard drive and when I boot to that instance I do not have the pop sound. I believe it's probably driver related, but I'm not sure where to look. Fresh disco install, have performed apt updates, and rebooted several times. Has persisted for several weeks.
