Comment 5 for bug 1426746

I am the original developer of audio-recorder, but I have not worked with it for many years now. I merely compile it for new Ubuntu versions without any code changes.

Ubuntu Studio 12.04 is a rather old distribution.
The newest versions of audio-recorder may work better. What version do you have?

Please see.

@Maxiride :
Audio-recorder is made for GNOME and Ubuntu desktops that has GTK3. I do not think it works well in KDE. KDE has its own audio stack and audio tools.
