I was having problems with sounds when resuming from sleep and I tried various solutions online but nothing has worked and actually things have gotten worst. I'm experiencing the following problems with sound:

  • Sound settings have disappeared from the system settings dialog and so has the sound status from the menu bar, I can still adjust the volume using the Fn key
  • Whenever the computer wakes up from suspend mode the sound plays through both the analog jack and the internal speakers
  • The sound cuts off periodically and I get the following error on VLC:

    Audio output failed: The audio device "sysdefault:CARD=PCH" could not be used: Device or resource busy.

So is there a way to revert to the original ubuntu sound settings without reinstalling the OS altogether?


  • Status icon fixed with: sudo apt-get install --reinstall indicator-sound-gtk2 but sound settings still missing
  • ...if you have a list of all the thing you did, and you post it, maybe someone can help. Without that, a crystal ball could be the only solution.... Unless you changed only things in your home directory, in which case creating a new user should suffice. – Rmano Oct 22 '15 at 20:06
  • I can suggest the following - try running gnome-settings-daemon from the command line, play around with alsamixer . Try reinstalling indicator-sound-gtk2 with sudo apt-get install --reinstall indicator-sound-gtk2 and if that doesn't work try volti, which is a volume icon similar to default volume indicator, or gnome-alsamixer, which is a graphical front-end to alsamixer ; I use both in my minimalistic GUI with openbox. Your sound appears to work, but not the graphical interface to it, so issue isn't bad - there has to be a simple solution. – Sergiy Kolodyazhnyy Oct 23 '15 at 0:23
  • @Rmano I wish I could tell you but I can't remember, some of it involved playing around with pulseaudio/alsa and some configuration files... – Lucino Veo Oct 23 '15 at 7:24
  • @Serg Okay the status icon is back but the settings are still missing from the system settings dialog. Running gnome-settings-daemon outputs the following error: You can only run one xsettings manager at a time; exiting – Lucino Veo Oct 23 '15 at 7:26

All references to Applications in this answer refer to the applications menu item in the control panel.

Xfce - Audio Mixer

(See note below)

As Xubuntu uses Xfce desktop environment you could install Audio Mixer, xfce4-mixer, if it has been removed (optionally with --reinstall).

$ sudo apt-get install xfce4-mixer

and use the Audio Mixer found under

  • Applications -> Multimedia -> Audio Mixer


$ xfce4-mixer

then tweak around.

Control panel

To add it to your control panel go to settings manager:

  • Applications -> Settings -> Settings Manager
    • Select Panels


  • Applications -> Settings -> Panels


$ xfce4-panel -p

Then select the Items tab and add (the [+] button) where you select Audio Mixer.

This is a very minimal audio controller. (Volume up/down - what else does one need?). To configure simply right-click the control-icon and select Properties, or select Run Audio Mixer if need be.

PA - pavucontrol

If you run Pulse Audio (Wikipedia) you could also use the PulseAudio Volume Control. Should be under Multimedia if installed, or start it from command line by:

$ pavucontrol

If not installed the package has the same name.

$ sudo apt-get install pavucontrol

This is the one I mainly use to adjust sound settings by GUI. (When not using JACK)

Note: Audio Mixer

As per Xfce 4.12 release notes:

“Due to gstreamer1.0 having dropped the mixer-interface entirely, and xfce4-mixer and xfce4-volumed relying on this interface with gstreamer0.10, our mixer application and volume daemon cannot be ported to 1.0 and are consequently not maintained anymore.”

As such I guess it would be best to rely on other controls such as pavucontrol in the future unless Xfce comes along with a new one.

But, it should work, and works fine here. I have both gstreamer 0.10 and 1.

Only to note that it could disappear in future releases.

Sub note:

After last update the audio settings was all re-configured as well as several others - such as keyboard tuning (I have for example a much lower repeat delaaaaaaaaaaaaaaay then default etc.)

Audio card was switched to HDMI (on monitor) instead of internal. Disabled audio such as input microphone was switched on etc.

Passed by here as I wondered if anyone else had similar issues.

  • Thanks for your help... I don't seem to be having anymore issues with sound after a normal boot up. But things are still sketchy after resuming from suspend...sometimes it's fine, sometimes I have to restart to get the sound working again – Lucino Veo Oct 30 '15 at 9:23
  • @LucinoVeo: What is your setup? Do you run a "clean" Xubuntu? I have a modified hack. Do you use PulseAudio? Do you have pavucontrol (as mentioned in post) installed? – Runium Oct 30 '15 at 15:54
  • it seems like things kind of mysteriously sorted themselves out... I hope your post can be of use to someone else anyway! Thanks – Lucino Veo Dec 2 '15 at 10:31
  • Still missing in 16.04 and the Audio Controll / Volume will not be set in Settings or the pannels, old one still in indicator plugin - but only working partially! – Ken Mollerup Oct 19 '16 at 10:10
