No Sound in Steam
Steam No Sound - Bug Fix
This is a known Steam bug, the easiest fix for this is making a link to:
sudo ln -sfv /etc/machine-id /var/lib/dbus/machine-id
In Manjaro there's /var/lib/dbus/machine-id created so just delete it as root and link again, works like a charm without scripts and such.
Use the following command in the Terminal to remove /var/lib/dbus/machine-id
sudo rm /var/lib/dbus/machine-id
