No Sound Coming out of Speakers

[Geoff J]

First post

I hit the volume first on the keyboard

Then I tried the speaker icon in the upper right corner in the top bar

Then I tried System preferences and the sound

tried boosting the volume on all 3 and nothing

I even shut it down for about 45 minutes and re-booted to no avail

was working earlier today with no beef

I did notice that the start up chime is silent on re-boot

I attempted PRAM to no avail

I shut down rather than restart

I hit the "on" button and waited for the boot sound (since the chime is silent)

I waited 2 seconds and then hit the PRAM

I got the chime sound, but it didn't ring out as long as it usually does and it got cut short

I then proceeded to the music selections in Itunes, and still no sound

Hi, this may be a dumb question. Do you have a speaker connected to the head phone output jack? If so make sure its on or unplug it to make sure the built in speakers are working. My apologies if it's a stupid question.
