I'm running 12.04 with KDE. Not Kubuntu. KMix is misbehaving.
The volume control is resetting itself to zero volume. The speaker icon is marked red. Kmix produces the following when I run it in a terminal:
`enter code here`QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.`
Kmix does not launch after that.
I use the "Default Audio" on the board. There is also HDMI audio I don't use. Kmix wants to use HDMI. When I set "Default Audio" as preferred, it reverts back to HDMI.
When this happens, alsamixer shows all channels have been muted. I can unmute them, but "alsactl store 0" produces this: "Home directory /home/abcdefg not ours"
