#StackBounty: #sound #bluetooth #skype #microphone Headsets mic not working on skype Ubuntu 19.10

Bounty: 50

I have a problem using skype and my headset, I’m using ubuntu 19.10 and skype is on version the headsets I’m using is Aventree ANC032 my problem is that my bluetooth headset’s mic is not working in skype, to make it work, I have to go into sound settings and change my output configuration to Headset Head Unit(HSP/HFP) and change my input device to my headset mic, it will then work but the sound is changed to mono and it sounds terrible, when the call is done, I need to change the output configration back to High Fidelity Playback(A2DP Sink) to get better sound quality where you can actually hear something, changing configurations in skype itself does nothing.

Sometimes the above method doesn’t work and I need to unpair my headset and pair it again, then change the configuration in my sound settings

It’s very annoying to do this each time I need to take or make a call.

How can I change/fix this, to keep my sterio sound but still have my mic work?

#StackBounty: #18.04 #sound #alsa No microphone in Ubuntu 18.04 on HP elitebook

Bounty: 50

I installed Ubuntu 18.04 on my new HP elitebook 850 G6 after erasing windows. I could not get audio input part working though..
Fn F8 key is orange all the time and this is how settings looks like.


I installed pavucontrol, but that didn’t change anything. What I have noticed is that I cannot check “set as fallback” permanently.


Also tried editing /etc/modprobe.d/alsa-base.conf by adding

options snd-hda-intel model=auto

Sound control still does not recognize any microphone

#StackBounty: #drivers #nvidia #sound #alsa After ubuntu 19.04 update, sound card cannot be detected

I have used software update. After then there’s no sound.
After spending hours reading similar problems I realize that none of them (including reinstalling alsa and pulseaudio) works for me.


lspci -v | grep -A7 -i "audio"

I get the following results:

It seems that despite the sound card does exits, the system cannot installing a proper driver. Following https://help.ubuntu.com/community/SoundTroubleshooting
I tried to instally snd-hda-intel driver but it returns:

sudo modprobe snd-hda-intel
modprobe: FATAL: Module snd-hda-intel not found in directory /lib/modules/5.0.0-29-generic

I then visit https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages
but I don’t know how to install the proper .tar.gz as a driver (possibly for oem-audio-hda-daily-dkms_0.201907080246~ubuntu19.04.1.tar.gz ?)
Can someone help me to work it out? Thanks!

dkms status returns nothing. Tried sudo apt update and upgrade does not solve the problem.

#StackBounty: #sound #kubuntu #headphones #19.10 No sound over headphones on a new Samsung Notebook 7 Force

Bounty: 50

I bought a new notebook and I’m having a hard time figuring out why it won’t output sound over my wired headphones. The notebook is the Samsung Notebook 7 Force and I’m running Kubuntu 19.10.

It recognizes them as plugged in and pavucontrol display things as if the sound is being reproduced. There is nothing muted on alsamixer also. Sound work fine with the onboard speakers.

I also noticed that the driver searcher thingy in Settings doesn’t show a list of hardware components, it only displays a message saying is getting information about the system (I don’t know if it is related, I just thought it could have something to do with missing drivers).

Being a Dell user since, well, forever, I really thought wonky hardware support was a thing of the past.

By setting the volume at 100% I can hear some sound: it is very low and it’s played distorted, kinda like a buzzing sound.


HDMI output doesn’t work also. This guy is having the same problem (S51 Pro is the model name of this laptop in Brazil).

I have a dual monitor setup with each monitor capable of playing audio, connected to a single RX5700XT GPU.

Right now I can select either one from the Sound settings to be the Output device.

#StackBounty: #sound #hp #realtek No sound except popping noises on my HP AiO (Realtek ALC225) for all Linux distributions

Bounty: 100

After erasing disk and installing Ubuntu 19.10 on my HP Pavilion 24-xa0506nz, there is no more sound coming from the built-in B&O speakers, except loud popping noises on shutdown, reboot, youtube videos launch… Now I am using Ubuntu 19.10, but the same thing happened with the following installations¬†: Ubuntu 18.04.3, Lubuntu 19.10, Kubuntu 19.10, Debian 10.1.0, Fedora 30, Fedora 31, Linux Mint 19.2, Manjaro 18.1.2 and openSUSE 15.1 (the sound was fine with Windows 10).

According to HP, the codec is Realtek ALC3259, but with the terminal I get

chris13@Pavilion:~$ lspci | grep -i audio
00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
chris13@Pavilion:~$ cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC225
Codec: Intel Kabylake HDMI

I’ve been trying to solve this for two weeks, checking many things from different forums.
Following Static and crackling sound coming from speakers in 19.04, I have added options snd-hda-intel power_save=0 power_save_controller=N
to the file /etc/modprobe.d/alsa-base.conf:
now the popping noises occur only on shutdown and reboot.

I have also added to /etc/modprobe.d/alsa-base.conf
the line options snd-hda-intel model=***,
checking for *** any HP models in section 3.15 of https://doc.ubuntu-fr.org/audio_intel_hda, but nothing worked.

Next, the line gsettings set org.gnome.desktop.wm.preferences audible-bell false did not change anything about the popping noises on shutdown (see https://www.reddit.com/r/linuxquestions/comments/9bs4tq/loud_popping_noise_on_shutdownreboot/).

I have tried to install the Realtek Linux driver (https://www.realtek.com/en/component/zoo/category/pc-audio-codecs-high-definition-audio-codecs-software), but it didn’t work (mistakes after the command make).
I have also spent some time with alsamixer and pavucontrol, but i still have no sound except popping noises on shutdown/reboot.
Note that the only “regular” Linux sound that I have heard was a normal “beep” sound after starting the computer on my Debian bootable USB.

There must be something wrong about the linux configuration of the Realtek ALC225…

Thanks in advance.

Edit: I know someone who has exactly the same computer and exactly the same problem! Besides, adding options snd-hda-intel model=alc225-wyse to the file
/etc/modprobe.d/alsa-base.conf did not change anything.

2nd Edit: I have created a bug report on Launchpad:

#StackBounty: #sound #pulseaudio #19.10 #microphone System sound playback is heard in microphone channel

Bounty: 100

When I do a recording of my microphone is also contains all system playback.

The sound settings dialog that displays the microphone input level live shows a full input level when I do the “Test” dialog on Output (“Front left/right”). The physical microphone is turned off/disconnected during this test.

I have tried the pavucontrol application and any “Monitor” stream in the Input tab is disabled and muted.

Other than that the mic and output works fine.

The headset is connected to the mobo with standard connectors.

  1. I factory restored the headset following this instructions. Then I was able to pair and connect to it. But when I put some audio through it, it feels like there was a lot of interference with only some random very cut noises that I couldn’t even relate to what was being played. Then I was able to disconnected and connect again but now no sound is being played at all. Then after 1 min or so, the headset lost the connection.

I’ve been searching for more than 2 hours and applying all possible solutions I found, but none of them fixed my problem, so I reinstalled Ubuntu 18.04.3 from scratch.

#StackBounty: #bash #sound #suspend Ubuntu mute sound when laptop lid closed

Bounty: 50

I find it annoying when I forget to stop videos before closing my laptop and then having sound played when opening it in public.

I tried to add a script to /lib/systemd/system-sleep:


amixer -q -D pulse sset Master mute

echo 2 >> /home/user/test

The script seems to be called when suspending as new lines are being appended to the “test” file (twice – which might indicate that the script also runs on resume – can someone confirm this assumption?)

Either the sound system re-enables itself automatically or something else is wrong. But the amixer command executed manually works fine.

Any ideas?

#StackBounty: #drivers #18.04 #wireless #sound #dell Wireless/audio not working on Dell Vostro 15 5590 with Ubuntu 18.04.3 LTS

Bounty: 50

I am posting this as I’ve gone through several posts here and couldn’t understand exactly the issues I’m having and the solution.
I recently bought a Dell Vostro 15 5590 (see here for all specs). Relevant hardware information:

  • 10th Generation Intel Core i7-10510U
  • Wireless adapter Intel 9462 NGW
  • Audio controller Realtek ALC3204

It came with Windows 10, but then I decided to install Ubuntu 18.04.3 LTS alongside it. When I first booted into Ubuntu, I noticed the wireless wasn’t working. The card wasn’t even showing up in the UI, but with lspci I could see it. After a thorough search I found this which worked. I basically installed the linux-oem-osp1 package and after a reboot I was able to connect to a Wi-Fi network.

However, I then noticed that the audio wasn’t working, neither input nor output. In the UI it was only showing the dummy output but again through lspci I could find my sound card. Found some questions here but nothing worked. Does anyone have any clue about this?

UPDATE: About the sound issues, I tried all the alternatives provided in this link. For the step where I should run the alsamixer utility, it failed with the message cannot open mixer: No such file or directory. I believe that is because it cannot find any sound card?
