Volume control problem in Lion

MBP 13" mid 2010 (7.1) just installed a fresh copy of Lion. After reboot volume control does not work (audio device - which is internal speakers - has no controls), but there is sound. After inserting headphones the volume control starts working, and remains functional after removing the headphones.

Basically after each reboot I have to temporary plug headphones to get volume control working. Nothing in dmesg or system.log

I'm familiar with linux so if you tell me how to debug this I'll happily do it, not afraid at all of command line or searching through logs.

(and you'd think that having control both over hardware and software would prevent such frustrating problems)

Macbook Pro 2010, Mac OS X (10.7)

I tried almost everything in this thread, and none of it worked for me. I think what happened for my case is that I was editing in Premier Pro CS6, and I changed the audio preferences in PPCS6, and in System Preferences, while editing on an external hard drive. I then shut down the computer before ejecting the hard drive.

When I started the computer back up with the hard drive not attached, the system would not play audio. But after attaching the hard drive, and restarting the computer, it appeared to work.

Lesson learned? Eject hard drives before shutting down in Lion while using CS6.

Thanks SundanceX 😉

1. I enabled the F1, F2, etc keys to function as standard function keys option.

2. I held down the fn key and the shift key to increase/decrease volume (using fn+shift let's you increase/decrease volume without the sound effects.

3. I plugged in earphones and played a song on iTunes then increased/decreased volume via keys + fn-key

4. I unplugged the earphones and set the function keys back to the previous behaviour and the sound controls worked fine ever since, even after restarts

That saved my day!

And allso...insert and remove headphones jack more "gently"...it looked like 2 work allso 😝...don´t ask me why...maybe an electrical defect?

- i plugged the headphones back in to the computer and started playing some music.

- while the music was playing, i adjusted the volume.

- finally, while the music was still playing, i removed the headphones from the jack, and this time, the volume buttons continued to work.

This one finally worked! (I removed Boom beforehand though).
