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

Having same problem. Extremely frustrating! I can't believe there's no official word from apple on this. My machine is useless for itunes, Final Cut, Premier, training video, skype.... In other words, sound is NOT a "nice to have feature". I don't understand how this is not a Pri-1 bug to be resolved.

I have tried all the fixes here and quite a few others that I've found outside these forums. Nothing works. I have reinstalled Lion (over the top of existing) as well. Still nothing. I don't see how it's a 3rd party software issue either, at least not for me since I didn't add anything between when things worked and when my sound components vanished.

I'm on a MBP 17" purchased in July 11. I don't think it's a hardware issue.

Man, I REALLY don't want to rebuild this machine from scratch.

If Apple thinks they can distribute a new OS via app store only, then the upgrade path should be flawless! This is certainly NOT flawless!

I'm ****** off apple!

I know I'm a little late at upgrading my OS but I had my resaons. haha. When I got the time to upgrade it yesterday, I thought that my system was fine until I wanted to watch something on youtube. I tried my iTunes and it had also the same problem. No Sound. and iTunes won't play the song.

Panicked. Read this. Tried the audio midi thing and BAM! Thanks a lot. Merry Christmas!

I have a HS-04B Genius headset when i plug it in to my 15" MacBook Pro to the Audio out port it works and i hear the output sound when i connect the mic jack to the audio Line-in port the mic doesn't work.....................................Does any one have an explanation...............

I'd like to add another twist to this mystery:

I recently moved to a late 2011 MacBook Pro, i7 processor, Lion 10.7.3 (11D50b).

When using a Plantronics Calisto Bluetooth headset with UBA-100 Bluetooth adapter and Dragon Dictate 2.5.2 to dictate text there is no problem. With Sound Pref's set to Input this headset, it works fine with various applications.

However, when using this same headset with Sound Pref's and Sound Effects set to Output to this device, there is no audio through to the headset from Lion's Text to Speech utility. I do get sound from this headset with iTunes and with YouTube - haven't tried other sources - as I would expect with these Preference settings. But nothing from Text to Speech!

I have Snow Leopard 10.6.8 installed on an external hard drive. When running the 2011 MacBook Pro from this drive, the Text to Speech sound is there. So it looks to me that the problem is in Lion.

I have tried dropping the "coreaudiod" process as suggested in this thread, but with no effect. I have also tried some of the usual things such as changing Sound Pref's, restarting the OS, and unplugging, replugging, and resetting the headset. No change.

Any insight and help would be greatly appreciated.

KIlling "coreaudiod" in terminal or with the Activity Monitor does NOT work .. and "coreaudiod" returns as a active 'Process' in the Activity Monitor.

This problem absolutely SCREWED a Mac DJ at a local event where he was supposed to perform before a band with several hundred people in attendance.

SHAME ON YOU APPLE!!!

There is no reason such basic issues should be released in the public.

You ruined the poor guys night from your lack of quality control.

Also .. this issue has seem to been around for a while .. and yet you dont address it.

WWW TTT FFF?

Also having this issue. Closing all applications did not fix it. I also tried logging out (Since I have 2 users) but I did not get any response in sound when trying to turn my sound up and down with the F11 / F12 buttons.

Running 10.7.5
MacBook Air 13" Mid 2011

1,8 Ghz Intel Core i7

4 GB 1333 MHz DDR3

Same problem here, tried to reset EFI and PRAM. No success =(

I also have this issue, seemling after my MBP sleeps for a bit. Only way to get sounds back is to reboot.

Ughhh... I thought I was the only one. No solutions yet. Same thing's been happening A LOT to me since I upgraded to Lion.

I use X11 almost every day but I have never had that problem... 😕

Well, great to hear that you fixed your problem! 😀

cheers!

I don´t use the X11, and the problem persists 😟

Anyone has another suggestion?! I want use my headphones =/

Cheers!

Same problem here. Praying for a fix. Strange thing is sound still works on web videos, but VLC and Quicktime have no audio and iTunes won't even play (stays at 0:00)!

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?
