with the new steam voice, in-game voice is now broken on my system (alsa dmix on realtek HDA chip). Cannot test anymore.
Maybe related or not, but streaming for a longer period of time to the steam-link hardware also starts producing scratch sound (happens after tens of minutes). It looks like a timing/sync issue. With the steam link if you choose to stop streaming, but leave the game running, and then reconnect to the game the scratchy sound disappears. This leads me to believe that it is a sync problem.
cannot reproduce. Will re-open if back.
