So I went to listen to some music tonight on my laptop and there was no sound coming out of the speaker. I tried unmuting, adjusting volume, checked that there were no other applications that might be monopolizing the sound. I opened up system preferences and made sure it wasn't muted there either. The volume controls started to respond very slowly. Like 5 seconds after pressing the volume up or down key it would respond. I shut down the laptop and when it rebooted I went to the sound section of system preferences and there was no audio output device detected. The sound was working fine earlier and unless someone came into my house while I was in the shower and smashed my speaker, I know of no physical shock to the system that may have caused this. Could this be an issue with Snow Leopard? I installed it two days after it was released. Haven't had any issues yet. Any word on this happening to anyone else before? Any idea what could be causing my speaker to just magically disappear? Thanks in advance!
