To be honest I did check, I just restarted the computer.

What does the red light mean?


I was still getting sounds, just couldn't adjust it

Red light indicates its using optical digital out. There's a small switch in the port that can get stuck on older MacBooks which stops you adjusting the volume.

Must have been something else in this case.

First off I was meant to say I didn't check to see if there was a red light. I just restarted the computer.

The only thing plunged in was a lighting to Ethernet adapter and maybe the charger.

Check the sound settings and make sure the correct sound output is set.

ok,
so after turning off my laptop over night and turning it back on, i have the same problem again, where i hear stuff, but not adjust the volume.

If i place the volume icon in the menu bar it looks grayed out.


When looking in settings it says "play sound effect through" selection option, and i change it to international speakers and nothing happen.

The other two tabs say internernail speakers..... and there is no red light in the headphone jack.

I assuming a restart will fix this, but does anyone know why this is happening? My laptop is only a week old.


Edit: It seems to only happen after a cold boot.
I have reinstall OS X once because i had a file vault problem, could this be a problem of a bad install


edit 2: No idea if it only after cold boot, as whilst i had problems after a cold boot, i plug my headphone in and out, and then i just adjust sound then did a cold boot and it work......

I guess i need to keep testing more

Sorry, I scroll back and didn't catch that line lol.
So bring it to the GeniusBar if you have an Apple Store nearby. It's the best I can suggest.
