[B450M DS3H, Realtek ALC887-VD] Sound is occasionally distorted

[Mike]

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.

The most likely cause of distortion is a bad connection or bad cable on the headphone jack.

Please try some other cables, other headphones, and other jacks if you have any more.

[Mike (mhensley78)]

The whole system is brand new including cables. I've used ubuntu 18.04 on
this machine since Christmas. No problem at all. Nothing was changed except
the format and install of 19.04beta.

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.

[Daniel van Vugt (vanvugt)]

Although maybe you're not talking about distortion in the same way I am. It's possible this is bug 1821663 so please try an older kernel version like 4.18...

https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

[Mike (mhensley78)]

Thank you. I don't know if you know anything about guitar but it sounds
like a distortion pedal was activated. Overdriven sound. The volume was low
and I was watching a YouTube video in firefox. It started the distorted
sound in the middle of the video. I paused it then left. Came back about a
half hour later hit play and it played fine. It has done this only twice.
Again, thanks for the help and thanks for Ubuntu.
