Up-to-date fedora 20, with the latest beta steam client, voice and sound are scratchy: https://bugzilla.redhat.com/show_bug.cgi?id=1159089
I should add that sound from a video in the steam client (currently up-to-date beta) is ok
Upgraded to fedora rawhide today. Pulseaudio is fixed there. It's a bug in pulseaudio stack on fedora 20.
Nothing extracted yet.
