For a few month now, the sound doesn't work on my Ubuntu 16.04. I tried some things to resolved that but I can't remember what I did.  Today, I checked my CPU usage as every day and I saw PulseAudio with 10-15% of CPU usage but I don't use it (sound off/no source of sound is running).  If someone has a idea and/or a solution for this huge CPU usage, i'll be grateful.

On Ubuntu 16.04.3 LTS  Pulseaudio causes Xorg to use 100% CPU.  After disabling autospawn in /etc/pulse/client.conf and killing pulseaudio CPU immediately drops to acceptable level. After restarting pulseaudio Xorg returns to 100% CPU.  pulseaudio --kill pulseaudio --start   Installed versions:  pulseaudio 1:8.0-0ubuntu3.7 xorg       1:7.7+13ubuntu3 nvidia-390 390.30-0ubuntu1    How to fix this?

Since I switched to Ubuntu 12.04 I'd only missed one thing.  A program which could launch typewriter sounds while typing. For instance, in Windows I used this:  for a long time.  I learned then that this writing program:  had the sounds but only for the program itself.  However, sometimes I'm writing an email, writing on the web or doing more complex writing tasks in LibreOffice - all places where these long missed typing sounds don't apply.  Does any of you know of any plans in the community of the sound bit - typing sounds - as an independent program or applet to be fetched in the Ubuntu Software Center soon?

I have an internal microphone in my laptop. I think it uses Intel High Definition Audio. But I can't get it to work with Ubuntu. It doesn't work with either the Sound Recorder or Skype.  On the Input tab in 'Sound Preferences', I just see Internal Analog Input Device...

I want my computer to play a custom sound file when my battery is low (say 10%). How can I do this? Thanks

I am using external USB audio card to handle speakers, also got the headphones connected to jack port. I need to switch them few times a day and getting extremely frustrated, as the only way I've found is:   Open search tool. Type: se. Click on 'Settings'. Navigate to 'Sound'. Change output to desired one.   On Unity I could navigate to 'Sounds Settings' from the audio icon in the tray. No idea how to do that on GNOME. Other than this finding GNOME superior to Unity. Happy that Canonical made that move.

I have installed Civilization 5 retail version with an update pack called update 7 via WINE and while the game runs well I am unable to get any sound working.  I am running 12.04 and version 1.4 of WINE via APT.  Any suggestions on how I could get sound working?

After I updated to Ubuntu 18.10 my sound device isn't recognized anymore. Only a dummy device is shown.  I have an onboard Intel device:  lspci -nnk | grep -A2 Audio 00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)     Subsystem: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller [8086:2036]     Kernel driver in use: snd_hda_intel     Kernel modules: snd_hda_intel   The command pacmd list-cards does not show any devices:  :~$ pacmd list-cards 0 card(s) available.   This message in /var/log/syslog might have to do something with the problem:  Oct 19 21:02:06 MyComputerName pulseaudio[14331]: E: [pulseaudio]  backend-ofono.c: Failed to register as a handsfree audio agent with  ofono: org.freedesktop.DBus.Error.ServiceUnknown: The name org.ofono  was not provided by any .service files   Does anybody have the same issue? How can I fix this?

I've just built a new PC:   Intel Core i3 2100 CPU 4GB 1333MHz DDR3 memory Intel H67 Chipset motherboard Using the onboard graphics Using the onboard sound - Realtek* ALC662 audio codec   When playing audio only it appears to be OK, but when playing videos and games the sound will repeatedly cut out for approximately a second 2 or 3 times and then start again. When it does cut out we get a notification that the speakers have been unplugged (although clearly they haven't).  One piece of information we found indicates that it's  and this does seem to be the case. It would also explain why it's more of a problem when video is involved as the CPU is doing everything.  We've checked that we've got the latest drivers installed and if anything the problem seems to be getting worse.  Is the only solution going to be getting a dedicated graphics card?   doesn't answer the problem.

Throughout the day I notice that my computer makes apparently random device-connect and/or device-disconnect ("boink") sounds.    I suppose it is the same sound you hear when connecting or disconnecting a USB device such as a thumb drive.  I've noticed that this happens on each of three computers I work with at home, my wife's computer, and my machine at work.  It happens without any user action at all - i.e. I'll be just sitting there (hands off my mouse and keyboard), and the computer will make the sound.  There is no visual queue or anything.  Just the sound.  I have sometimes gone in pursuit of the sound - running virus scans, examining event logs and such, and observing task manager - but have never had any luck tracking this thing down, but have not had any luck.  I've been noticing this since Windows Vista and now the sounds have followed me through to Windows 7.   Surely someone else out there must be experiencing this and can explain what is happening.

After installing Ubuntu 13.04 x64, I realised that my sound wasn't working (only headphone showed up in settings).  Following , I manually added my Dell Studio 1740 audio hardware to:   options snd-hda-intel model=dell-m6   Within etc/modprobe.d/alsa-base.conf.  Using the test speakers feature, I found that no sound was coming out of my right speaker (the one with the power and volume dials).

Since I updated Ubuntu from 16.x to 17.10 and then to 18.04 I don't have any sound. There is also a problem with videos in web browser (they look like a slideshow, still no sound) and Spotify, where it looks like music is loading but nothing happens.

I have upgraded to Ubuntu 14.04LTS from 13.10. Before upgrade sound was working fine, but after that its not working. I tried solving this issue from a reference link     but still my problem is not resolved.

I updated to Ubuntu 15.04 from Ubuntu 14.10 a few days ago, and now my Logitech G230 headphones don't receive any sound. How can I fix this? PulseAudio Volume Control detects my headphones, and says they're working, but no sound comes through.  EDIT: Using alsamixer worked at first, but now it doesn't, and I get frequent bursts of static through my headphones now.

Using Ubuntu 16 LTS  I installed ubuntu on my new asus zenbook3 ux390. Nearly everything works fine except the volume controls don't work. The volume is either on or off. I can adjust volume in specific apps or websites (like youtube) successfully, but the internal volume control either wants to be muted or at 100%.

I've installed Ubuntu 12.04 LTS from a minimal cd on a netbook (Asus 1001 PXD). I've installed the ubuntu-desktop package using the --no-install-recommends option.  Everything works fine, except the "sound test" for headphones or analog speakers.  Clicking on the "test" buttons (front left and front right) I don't hear any sound. Despite this, the audio is working properly.  I've checked the audio levels with alsamixer; I have also checked that the test sounds actually exist in /usr/share/sounds/alsa.  I tried an installation of Ubuntu 12.04 LTS made with the desktop-cd, and in this case the speaker test works properly.  I suppose, therefore, that the problem could depend on the lack of a package, but I have not identified which one.

Is there an application for Ubuntu that can play audio faster but maintain its pitch?  This is possible in Windows using an application like PowerDVD.

I was trying to fix my audio problems using suggestions from . One of the comments suggested I execute this and only this:     killall pulseaudio   So I did, and I restarted my computer just in case, but all it did was remove my soundcard and I still couldn't hear anything. Now I don't know how to get my soundcard back.  Please note that I am extremely inexperienced when it comes to Ubuntu.
