hi everyone,
this morning my computer started with the mute box checked in system preferences/sounds and it's grayed so i can't uncheck it. Songs won't start on iTunes, i tried both with the internal speakers and headphones. i hadn't do any system changes recently, i updated to 10.7.4 when it just showed up. my iMac it's a mid 2010. please help.
thank you!
