Sometimes (very common) audio starts sounding distorted. This doesn’t happen to my laptop on Windows 10. I’m guessing it’s a driver issue. My laptop is Dell Inspiron 7580.
Hi wunzer0, I think the issue here is that Dell offer such kit with Ubuntu pre-installed - they will have created their own Linux driver for kit they ship with Ubuntu 18.04 LTS so it may prove difficult to obtain this but I would advise you contact Dell for advice - see this Ubuntu certified hardware specifically about your notebook and audio chipset:
