I have an intermittent but almost heart attack inducing issue whereby Ubuntu/PulseAudio/Alsa appears to suddenly cause an issue that causes an otherwise low volume audio output (Amp is not set to a loud volume) to suddenly spew out a crackling/hissing/static like noise, but almost as though the amp has been turned to top volume...
Today this was experienced using Kodi. Yesterday was experienced through Youtube in Chrome...
Strangely, I've not heard this in several months, but has now occurred twice in as many days...
I'm as follows: Ubuntu 20.10 (Also experience on 20.04) Kernel 5.9.10 (also experienced in pre 5 from what I remember) pulseaudio 13.99.2
Audio has been, but also experienced the same issues as: Audio over HDMI Audio over DisplayLink Audio directly to amp over 3.5mm
Interestingly, I also seem to have an issue that pauses audio for approx 100ms regularly...
Any ideas guys?
