Hi guys !

I have these warnings on Linux since I use Discord on my computer.

"déc. 15 14:00:02 Travis systemd[403]: Started Discord - Internet Messenger.

I think this is the root cause of a problem when I try to speak with friends.  My voice is distorted and interspersed.

I have install Discord on Archlinux via pacman.
