Today the same was happening, but I was in the process of swapping out my Wild Wasteland perk to get the YCS/186 so I couldn't save and restart immediately, and eventually this crossed over to audio as a whole that began to distort and cut out terribly before I restarted the system.
Has anyone had this problem before? Up until now I've never had this happen before in my life. It isn't particularly game-breaking per se, but I'd prefer not to have to restart my system every time this happens.
