Still ripping CDs to my computer and one CD caused Media Player to crash a couple of times last night. I've now lost all sound on my computer; nothing plays in Media Player (but, oddly, does in other programs like Musicmatch Jukebox) and none of the default Windows sounds play. The volume is definitely on and turned up... so what's happening?!
Two things I'd check is 'Sounds' in control panel (my pc has a habit of changing my speaker settings when it crashes. and also check Media players speaker/sound settings. (not sure where this is because I don't use Media player that much.
Also check the soundcard settings haven't been altered Sounds in control panel.
