All of a sudden my alert sounds (all the stock ones, no custom ones) are messed up. The one I use the most (Basso) just sounds like static now when it is triggered (e.g. backspacing at the prompt in terminal). Also, the individual .aiff files will not play in any player. Haven't been able to find anything remotely like this with extensive googling. System specs in signature.  the "pop" sounds you get when you adjust the volume is stuffed up too!
