Amarok doesn't start after trying PulseAudio
I recently did some experimenting with pulseaudio, one element of which was configuring the xine backend of amarok to use pulseaudio. However, for a number of reasons, I removed pulseaudio. I did so before changing the xine config back to Autodetect. My problem is that now Amarok won't start. I've run amarokapp from the command line and there don't seem to be any sound-related error messages, but my sound configuration has been reverted back to what it was for the ~6 months that Amarok worked, so I'm assuming it was the xine config change that broke it.
I can't seem to find where xine/Amarok stores this info though, I've looked under ~/.kde/share/apps/amarok/xine-config, but I don't see anything that looks relevant. Can somebody tell me where to change xine back to Autodetect without using Amarok? Let me know if I should post any files.
