Hi Michael, If your hardware volume up (F5 key) doesn't affect things and you're not muted, try looking at your Audio Output volume settings in the Audio MIDI Setup menu under your Utilities folder (Shift+Command+U under Finder).
Use the item chooser menu to first select the Audio Devices tab. Then, on that tab use item chooser to look for Audio Output and VO-keys down arrow to the table for the output entries. Interact, and check that the sliders for the left and right volume outputs are each set to 100 per cent. Audio MIDI Setup isn't something you'd ever think about checking, but the input and output settings can affect your audio quality and also the quality of your recordings. (I found out about this when I was reading reviews about the iMic a long time ago. This is a device to allow you to record audio on computers with no line-in -- like the iBooks. It turned out that there were a bunch of reviews complaining about the horrible quality of recordings that appeared all of a sudden, and then someone pointed out that the reason was that a recent Mac OS X system update had somehow set the audio input settings under the Audio MIDI setup to a really low bit rate and unbalanced input volume. Weird, but it did mean that this is one more thing you can tweak.) Incidentally, this is not the solution to people who are complaining about the low volume on some of the new Macbooks. That genuinely does seem to be true for some models. Hope this helps, Cheers, Esther On Dec 31, 2007, at 07:54PM, Michael Babcock wrote: >happy new years to all of you, I have a problem, my macbook wont let me here >the audio with out headphones in, yet when i plug in headphones, it works just >fine, I've tryed pressing fn+f5 repedly, and i still dont here any audio, >however with the headphones i can adjust the volume and suh, turn it up, etc, >and for some reason it just started with in the last hour or to.
