[xubuntu-users] Dell XPS, Realtek audio switched to wrong output device

Hi all,

I've a problem with audio output. I plugged in external speakers 
recently and suspended the box without unplugging them first. Now the 
internal speakers don't work any more, only the external ones. I did 
start the box using windows and I was able to fix the problem by 
selecting the so called "rear speakers" manually. I restarted the box 
then with xubuntu, but unfortunately it didn't have the desired effect 
there.

Is there any way in xubuntu to select the output device manually?

Cheers,
Andy
