Mac help: why is my sound gone?

Asked by lc (346 points ) August 26th, 2009

Recently, if my computer runs out of battery and shuts off, when I turn it back on there is no sound icon on the top bar, and when I try to adjust the sound, there’s an icon that appears that resembles a “don’t” sign (circle with a line through it). But, when I restart my computer, sometimes the icon comes back and the sound works without a hitch. But sometimes, it takes a few times of shutting down and restarting for the icon to come back. Anyone know why this happens and is there anything I can do to fix it? Thanks!

I think that don’t circle sign on the icon means it’s on mute…

nope, not on mute. :)
It has that ‘don’t’ sign even when the sound it at what should be full volume.
in my System Preferences, in the ‘output’ it says there are no devices found.
and the sound icon, that speaker looking thing, is just not there on my top bar, next to where the battery life icon is.

ooo looks like Mac isn’t as flawless as everyone says it is.

I would try deleting this file.
/yourusername/Library/Preferences/com.apple.soundpref.plist and restarting.

If that doesn’t help you could try making a new user account and see if the problem occurs in that account too. That can help us see if it is a system wide problem of specific to your account.

@MrGeneVan, anybody who actually uses one will tell you the Mac ain’t flawless. Regardless, it’s still superior by almost all meaningful measure to Windows.
