How can I disable login screen music?

Now that Riot has implemented a queue system at login, I spend even 30 minutes in the intro screen. I would like to mute the music there, so that I can play other games, see videos, etc. while waiting. Is it possible in some way?

Solution 1:

In the tray open the volume mixer by clicking on the volume icon and selecting "mixer". Using this you can mute specific programs/games.

Solution 2:

As of the latest patch, .12, there is an option on the log-in menu to disable the sound.

The Login Queue will now update your position more regularly The Login Queue will no longer lock the focus of the application You can now disable the Music at the main login page
