Change Vortexbox Volume

I use my Vortexbox connected to my Hi-Fi as a jukebox. The MP3s are store on the box and it can be controlled from any computer in the network via the webinterface or even from my Tablet.
The vortexbox player that is installed makes this possible. On the one hand you can change the volume using the webinterface but on the other hand the system volume can be also configured. After my installation the system volume was very low and I needed to change it.

To change the system volume, just connect to the box with SSH. When you run in the command

alsamixer

you get a simple command line based GUI. Here you can navigate with the arrow keys and adapt the volume.

After making changes in alsamixer it's important that you to store the settings with:

alsactl store
