I'm wondering if anyone else has encountered this, as it only seems to have happened suddenly (in the last day or so) and appears to only happen with Deadlock. I didn't have this issue until yesterday: recordings from before Nov. 11th were just fine.

At present it seems if you have Steam Game Recording set to "Game Audio Only" or "Game and Selected Program" then the replays saved from Deadlock have absolutely no sound. Setting it to "All System Audio" does solve the problem but I don't really want it recording all of my system's audio.

This doesn't appear to be happening with other games so I feel like it's a Deadlock-specific issue.

EDIT: All the other options have been explored for fixing the issue, i.e. restarting Steam, restarting computer, deleting background recording file, etc.
