I was in vent playing another game with some friends. When finished, FO4 download was complete, so I installed it.

In addition to a number of issues with FO4 itself, voices in vent are now faint and muffled but the ventrillo application sounds, and all other sounds on my PC are completely fine. (Note: voice in FO4 are also muffled, sometimes they work if I'm not facing directly at the NPC)

I completely uninstalled ventrillo and re-installed - same issue.

There were no other changes to my system between ventrillo working and installing FO4.

Anyone have any ideas what the issue is here? Been using vent for years and years and never had a single issue with it.
