tI've had this problem for a number of years on a range of Ubuntu distros; I'm currently working from an Ubuntu install that I switched over to Xubuntu after some graphics issues with the standard window manager.
The problem can usually be triggered when I have too many tabs open while one of them is playing Youtube audio in a background tab. Because of this, I suspect there could be a memory allocation issue; tried increasing available browser memory, but since I really have no idea what the problem is, I figured I would post here as well. Let me know if you would like any diagnostic outputs or something similar. Attaching some hw info. Please let me know if you would like a different diagnostic output. ** Attachment added: "output of "arecord -L -l"" https://bugs.launchpad.net/ubuntu/+source/speech-dispatcher/+bug/1739310/+attachment/5257361/+files/sound.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to speech-dispatcher in Ubuntu. https://bugs.launchpad.net/bugs/1739310 Title: Sound crackling in Ubuntu 16.04 Status in speech-dispatcher package in Ubuntu: Confirmed Bug description: Sometimes, when i’m watching videos in youtube or facebook, the sound is distorced with a “static sound”. After searching the web for a solution, i found this site (maybe it’s the same problem, with better explanations in english): https://github.com/mumble- voip/mumble/issues/2350 Always when i start the service “speech-dispatcher” for the first time while playing something with sound, the bug occurs. So, i think maybe the problem is with this “speed-dispatcher” service. When i restart pulseaudio everything becomes normal again… This problem happens in ubuntu 17.10 too. It’s a annoying bug and i don’t know the best way to report it. My specs: GPU: Nvidia GTX 950 Motherboard: Gigabyte 78LMT-USB3 (Rev. 6.0) CPU: AMD FX 8300 P.S: I'm using Xubuntu now but this bug occurs in all ubuntu 16.04 "family". Sorry for the bad english.
