Howdy All,

So when I booted into Kubuntu this morning I was greeted by the following lovely popup in the lower right hand corner of my screen:



Now, some of my audio still works (Wine programs & Pandora among a few other things) however my virtual XP machine (running under Virtual Box non-OSE) no longer out puts any audio.

Any idea what happened? I can confirm there is nothing wrong with my hardware and that it is a KDE/Linux issue because my audio still works 100% fine under Win7

Also here is the output of lspci on my hardware:

There are a whole host of us having this same issue over on the Kubuntu forums, however to this point no one has a solution. So thusly I am making a post here in one final attempt to get my sound working again under KDE before I switch back to Gnome (where it works fine).

Open to suggestions,
~Jeff

Well, it is not Amarok that causes this problem but Pulseaudio, which you shouldn't be using with KDE in Kubuntu.

The best procedure is to remove Pulseaudio (unless you us Gnome on a regular basis, then you will need it apparently), then remove the $HOME/.kde/share/config/phonondevicesrc file and restart KDE.

JFYI: this is something you should address your distribution with, Amarok doesn't handle sound itself, but lets Phonon do this, and Pulseaudio doesn't work well with Phonon. You could search the archives of or ask on the kubuntu-users mailinglist or in the #kubuntu channel on irc.freenode.net.

Also make sure you use the phonon-backend-xine and have the kubuntu-restricted-extras package installed for the codecs.

And BTW, you could have searched the forum a little, this has been discussed here numerous times already... I am quite astonished nobody knows a solution on Kubuntuforums.org as this is a recurring problem with Kubuntu since at least 9.04. Are you sure you didn't find mention of it in the archives there?

Thanks for the information.

Also did I mention Amarok anywhere, I don't believe I did... I have all my codecs setup so I know that was not the issue. I have un-installed PulseAudio for now. Appears to have resolved my issue.
