I've been having sound issues relating to crashing too, on Mint 13. Sometimes when porting to a capital (but not always) the music one hears when entering hangs. Disabling/restarting the sound in the options menu fixes that, but very rarely (and almost always when teleporting into Zora for some reason) will I just flat-out C2D.
