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
$ sudo apt-get install xfce4-mixer
and use the Audio Mixer found under
- Applications -> Multimedia -> Audio Mixer
then tweak around.
To add it to your control panel go to settings manager:
- Applications -> Settings -> Settings Manager
- 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:
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.
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.
