Strange noise in headphones when no sound is played

Question

There is a strange noise from my headphones on Lenovo T440. The sound is like when you tune your radio, but you get a wrong frequency and you hear unpleasant noise. The noise starts when Ubuntu 14.04 boots up and ends after a shutdown. It is coming out only through my headphones, there is no noise through the speakers.

The strange thing is that the noise disappears when any sound is played or if I enter sound preferences. But when a sound is stopped, it appears again after 10 seconds or less. Also, the noise goes way down (or maybe even disappears) if I put in my laptop charger and stop the music.

No matter how I change my volume level, the noise level is the same. It seems like the output is not disabled after sound stops.

sudo aplay -l

im on the lenovo t440s and this issue recently occured with my setup on 14.04 as well. as unrelated as it seems, my hunch is that it happened after I altered some /etc/x11/ mouse related settings and then restarted lightdm. was never an issue in the past and now its pervasive. — still_learning, Dec 27 '14 at 18:53
The problem was gone after I changed the beep channel in alsamixer from 0 to something else and back to 0 — EECOLOR, Nov 02 '15 at 01:01

Got the same problem on Dell XPS15 (9550, 2015 model in Xenial). Solved it in alsamixer and muting the loopback channel.

$ alsamixer

Navigating to loopback (all the way to the right, with → key) and setting it to Disabled using the ↑ key.

No reboot needed;
No root needed;
Is permanent as far as I noticed.

With this method, you can also keep the powersave on, and thus save battery. – Jonas Czech Sep 26 '16 at 10:09

There is no "Loopback" option on mine. Dell XPS 7390 w/ 20.04. The Headphone Mic Boost option also did nothing. Disabling Powersave (described by kvcx) worked, but would love to find a better option if this hurts battery life. – Brian C Jan 27 '21 at 04:03

It's possibly your audio interface going into power save.

If following commands clear the issue until you reboot or change the power supply it has got something to do with power save:

echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save_controller
echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save

I had the same problem on Dell Inspiron 3542 running Ubuntu 14.04.2

The problems appears to be in the audio powersave feature.

The noise stops when I open the sound settings, or when I play audio/video. The noise starts again when I stop playing audio/video and close sound settings.

This solution worked for me: Edit the file

$ sudo nano /usr/lib/pm-utils/power.d/intel-audio-powersave

change the line

INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}

to

INTEL_AUDIO_POWERSAVE=false

Reboot.

I faced no further noise after this.

I had the same issue. I believe it is the noise that your microphone picks up.

Go into Sound Settings, under the Input tab, check Mute box near Settings for <microphone_name> Microphone (Not the Mute checkbox at the top).

enter image description here

That should do the trick.

Following your instruction, my headphone is mute. – Tianren Liu Feb 27 '15 at 02:17

the microphone does not typically play over the speakers unless you run pactl load-module module-loopback latency_msec=1 – mchid May 21 '15 at 00:55

I had the exact the same problem and none of above method worked for me.

My laptop is ASUS ROG-G501JW and the sound card is Realtek.

I found the solution in this thread: White and hissing noise in headphones, not present in Windows.

Setting this line in /etc/modprobe.d/alsa-base.conf fixed all of my problems:

Do you have tlp activated?

If so edit /etc/default/tlp and set the power save option values to 0

SOUND_POWER_SAVE_ON_AC=0
SOUND_POWER_SAVE_ON_BAT=0

this did the trick for me

In /etc/pulse/default.pa and /etc/pulse/system.pa, comment the following line:

Or try to create the file ~/.config/pulse/default.pa with the lines:

.include /etc/pulse/default.pa

I just found this thread because I had the fuzzy earphones as well, but because of a different reason.

I have a USB fan plugged into my laptop and whilst it's turned on, I hear the fuzz on my earphones, so check if there are any devices on your USB ports causing the interference on your sound before testing the software fixes.

Solution

If this is due to the persistent battery mode of TLP then the solution is easy.

First, check if this is the case. Run sudo tlp-stat -s, if this shows Mode = battery (persistent), then that's the cause of it.

The Fix is simple. Infact it was pointed out by @Foxtour in one of the answers.

Create a new file /etc/tlp.d/95-YOUR-NAME.conf and add the following content
```
TLP_DEFAULT_MODE=AC
TLP_PERSISTENT_DEFAULT=0
```
Restart tlp
```
sudo service tlp restart
```

Background

I am using ubuntu 20.04. I have never configured TLP and the Dell laptop has a freshly installed Ubuntu. This happened due to these 2 config options added in /etc/tlp.d/50-estar-default.conf.

TLP_DEFAULT_MODE=BAT
TLP_PERSISTENT_DEFAULT=1

This means, the default mode is battery and this will be persistent all that time. It doesn't change even if you are on AC.

This configuration option was added by package oem-fix-misc-cnl-tlp-estar-conf. The apt-cache show oem-fix-misc-cnl-tlp-estar-conf shows this description

Description: customized configuration for tlp.
 This package carrys agressive policy to pass energy-star, and also some blacklist for problematic devices.

Now you know why this happened

I don't know if you still have this problem, but for me the solution was to lower the volume of the headset from the physical buttons on it.

If your headset has physical volume down buttons, turn the volume down using them. I guess the volume was so high it was transmitting the Bluetooth signals into noise.

A possible solution for any fedora users out there is to change the values in the following files:

/sys/module/snd_hda_intel/parameters/power_save /sys/module/snd_hda_intel/parameters/power_save_controller

You can use nano to open these files and replace 1 with 0 and Y with N, respectively.

Worked on my Dell M2800 Laptop.

I found an unusual cause for my excessive background noise... my Civilization 5 (run via Steam) was not exiting properly. The background noise I was hearing was from the game. I used "htop" to find and kill all Civilization processes and sure enough, the noise decreased every time I killed off a process from the game.

So not an Ubuntu nor audio problem; it was in fact one particular app (that never exits right anyway).
