Ubuntu: A simple, one-knob volume control for KDE (kubuntu)?


What's the easiest way in KDE (Ubuntu 13.10) to have a simple, one-knob volume control for the default playback device? Right now there's kmix in the taskbar, which shows 3 volume sliders, none of which actually controls the volume of the default playback device. (I have to click "Mixer," look through the various playback devices and find "Built-in Audio Analog Stereo.")

In those rare cases where one needs to see every single playback device and stream, kmix is great, but for the other 99% of the time when I just want to turn down the music, a simple taskbar volume slider would be appreciated. Thank you!


KMix backends

What's the easiest way in KDE (Ubuntu 13.10) to have a simple, one-knob volume control for the default playback device? ... "Built-in Audio Analog Stereo.")

The KMix supports multiple backends: The Kmix blog: http://kmix5.wordpress.com/ and an older topic: http://kmix5.wordpress.com/2011/12/30/winter-of-69-welcome-kmix-v4/

To get the "Built-in Audio Analog Stereo." option:

Right click the KMix and pick the 'Quit'

Add the PULSEAUDIO to the kmixrc as the backend. This can be done with the command:

kwriteconfig -file kmixrc -group Global -key Backends -type string PULSEAUDIO  

Start the KMix again - Alt + F2 and the command kmix.

The KMix should now start with the pulseaudio backend:

Click the wrench icon

and only pick the 'Playback Devices'.

After this the KMix should offer only the 'Built-in Audio Analog Stereo' option. At here it does.
