Mac OS X Lion: Sound problem after unplugging my headset/headphones.

Hello all,

I have an early 2011 i5 Macbook Pro, 8GB ram, 320gb HDD, recently upgraded to Mac OS X Lion. I've been looking through the discussions, but I haven't found any other topic with my same problem, unless I missed it.

My problem is: sometimes I will leave my wireless headset (Plantronics .Audio 995H, via USB) or headphones (via audio jack) plugged in for hours at a time. Once my headset battery dies, or I just decide not to use either my headset or headphones, I will unplug it. When I unplug it, NO sound is coming from the built in speakers whatsoever. Also, when I plug the headset/headphones back in to see if the sound is still going to play through them, it doesn't. I have checked my sound preferences after I unplug (System Preferences > Sound) and it's on the default "Internal Speakers" but no sound is coming out. I press the volume adjust buttons on my keyboard, and they work but still no sound.

This DID NOT happen when I had Snow Leopard..

The only way I can get my sound back is by rebooting. Right when I click restart, all the volume adjust sounds, Skype IM sounds play RIGHT before it reboots. I have done PRAM and anything else suggested by other users in the discussions to reset hardware but nothing has worked. Does anyone else have this problem? and did you find a solution?

MacBook Pro, Mac OS X (10.7)

I have an early 2011 13' MBP and as soon as I installed Lion my headphones quit working. I tried the fix by changing the settings In the Audio MIDI Setup and it didn't work for me. They are Shure se535 and I use them everyday with my Iphone so I know its not them. Hope there is an update soon to fix this, pretty big screw up iof you ask me, Apple.

Same problem here. I found an easy way to fix it without rebooting. Run terminal and do this:

sudo killall coreaudiod

The problem happens to me enough that I created an app to fix the problem. http://goo.gl/qyyGI

Before I figured out what was causing my problem, I tried this out too but it didn't work for me, unfortunately..

The only problem with that is you don't know my super user password, so how can the app actually work without prompting me for a password?

That command doesn't work for me anyways.

Thanks, works for me! That was driving me nuts... My problem is not with earphones like some here, but for every video/audio player (playhead not even going forward...).
