I have experienced distortion with many brand new cables in the past. And sometimes it only happens when they are twisted (e.g. a mismatched connection between 3/4 pin jacks).
Please try some other cables, other headphones, and other jacks if you have any more. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1822446 Title: [B450M DS3H, Realtek ALC887-VD] Sound is occasionally distorted Status in pulseaudio package in Ubuntu: Incomplete Bug description: Sound from youtube in playing firefox is distorted. After waiting a half hour the problem went away. i then tried to file a bug report. while playing the first set of test tones the test tone played fine after it finished the youtube audio was distorted again. then the second set of test tones from the troubleshooter played and were distorted as well. Also in the summary it ended up saying "FRONT" but it is the rear green jack on my motherboard that i am plugged into.
