High-pitched noise/buzzing in headphones

Post by sound66 »

Hi,

I've been using Linux Mint 20 for a few weeks now, but for the last few days I've been having a strange sound problem. As soon as I start something that has to do with the audio output (for example, the audio settings or a Youtube video) I hear a noise in the headphones. The noise then disappears again when the audio output is stopped. Strangely, the problem disappears as soon as I unplug the headphones and plug them back in, but I would like to know what is wrong.

I am using Mint 20 on a dual boot system together with Windows 10. The headphones are in-ears with a microphone and connected through an AUX cable.

I don't know if it's related, but the problem appeared around the time I first used the microphone in windows 10 a few days ago. Of course, Windows 10 always shuts down completely (no fast start or anything else). The problem persists when I boot from windows to linux and vice versa or from linux back to linux.

What else I noticed: When booting Mint through grub, I once saw the logo of my laptop manufacturer for a very very short second, which actually belongs to the windows boot loader. I do not know if this is also related.

It all seems that when my headphones are connected during the boot process something runs wrong and return back to normal as i replug the headphones.
What i also noticed: The microphone from the headphones are not recognized until i replug the device.

Thank you for your help.

Hi sound66, and welcome to the forum.

Let's start with the noise issue first. Run this in the terminal then reboot and test if the noise is still there:

Code: Select all

sudo tee /etc/modprobe.d/snd-hda-intel.conf <<<'options snd-hda-intel power_save=0'

Hi MrEen,

Very thank you for the fast answer.

I run the command and rebooted, but the problem is still there.

Okay, it was a bit of a guess, but it's probably fine to leave that in place.

If you mute your microphone in the sound settings, does that stop noise? If not, let's get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999
The last line of output will have a URL pointing to the info.
