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

Hey guys...

All that stuff didnt work for me....

I had to Format my SSD, tried backing up from my newsest backup same problem again.....

I noticed this problem occure after installing CS5.5 master collection or Pro tools....

So what I did was Format the SSD again... Installing Lion... then I chose a back-up from a older date...

WORKED!!!!!

I was then able to instal CS5.5 and Po Toools 10 with no problems....

I would really like to knbow what cused this problem...

Peace.

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.

What works for me is the fix suggested to me when I first posted this, and used it again today and it worked again. I have only had to do it a few times in the last several months.

I am using 10.5.8 though.

"Run Activity Monitor and find the process called "coreaudiod", select it and press Quit Process."

Then restart.

This works for me too to avoid restart. I'm using Lion 10.7.3. Thanks!

Has anyone recenlty installed LogMeIn?

I did, and it hijacked my audio device and as a result...no audio.

Solution:

System Preferences > Audio MIDI Setup 'Right-Click' on Built-in Output > Use this device...

I have had this same issue and am not sure what happened, what caused it.

My fix was to go to Preferences > Sound > Output and make sure the 'Internal Speakers' was selected. I had 3 options in the output selection box and am not sure where the other two came from. There was the one needing to be selected, 'Internal Speakers', then there was two 'Soundflower' options; a 2 channel and a 16 channel. I don't have a clue where they came from.

Selecting Internal Speakers restored my sound. Hopefully this helps someone...

I also noticed that I had the same problem after installing LogMeIn. My plan of action next time my sound gets muted out is to go into System Preferences and make sure that the "Headphones" are selected and not the "LogMeInSoundDriver."

I tried unplugging my headphones and then plugging back in. I haven't had the problem of getting sound back in headphones nor through the Mac's speakers.

Thank you, marcusleemitchell!!! I was completely stumped until I saw your post about LogMeIn and remembered I had recently updated the plug-in. Went to System Prefs > Sound > Sound Effects and chose "Play sound effects through: Internal Speakers." Voila! Sound is back! MacBookPro, OS X 10.7.3

Doing the 'sudo killall coreaudiod'

...fixed the issue for me! Thanks. Lion sure is buggy.

For those who the killing of coreaudio process did not work, how about killing the process called 'coreserviced' on Activity Monitor?

I'm on Early 2011 Macbook Pro 15 with OS X 10.7.2. Force quitting the 'coreaudiod' did not work for me, but the killing of the 'coreserviced' somehow did. Just in case this worked for some other people too.

I should probably add that killing the latter, although having fixed the sound, also crushed Finder for some reason.

Does anyone know if upgrading to OS X Mountain Lion will fix the problem forever?

I have the same exact problem on a brand new Mountain Lion just bought....so sick!

here's one easy solution to yall. worked for me.

plug back in ur headsets. keeep pressing the increase /decrease volume control button (HOLD THE BUTTON)

then quickly unplug ur headsets with the beeping sound.

pce.

sudo killall coreaudiod (typed into Terminal utility app)

worked for me. It cleared some sort of queue blockage and I heard all the backlogged mail checks and whooshes!

Thanks

I had the same problem, but this thing fixed it for me: http://kyen99.tumblr.com/post/8573258536/mac-os-x-lion-audio-fix

I hope it will help someone 😀

Cheers

I've had this problem with my MBP since I bought it (13-inch, Early 2011). Having to kill coreaudiod all the time has been a hassle.

Updated to 10.7.5 yesterday and it now appears to be fixed. Hope it stays this way!

Anyone else have luck with 10.7.5?
