How to change the default output device?

Hi guys, I'm using Open Suse 13.1. I connect my monitor into my notebook using a HDMI connector (the monitor has no sound output) and I connect my speakers using a standard P2 connector. The problem is that everytime I boot my system, I have to manually change the input device from "HDMI / DisplayPort" to "Analog Output". Here is a printscreen:

How do I set the option "Analog Output" as default, so I don't have to change it in everyboot?
