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

I have the same problem.

I can only unlock by connecting and disconnecting the audio headphones.

now I can unlock it through "LionAudioFix".

when the final solution from Apple?

Ironically, I called Apple about something like that a few days ago (because my external speakers were not working with the mac and I had to reboot to get the sound back) The technician said: "Call the manufacturer and ask them if their product is compatible with our OS." 😮

So, in short & under theory there are many devices (including speakers & other sound devices) which will need to be specifically made for OS X Lion. Even if they worked under Snow Leopard, they might not work in Lion... 😢

Thanks very much for the app, kyen99!

My problem was that once I unplugged a set of exterior speakers, the volume control icon was grayed out and the controls inactive, and I was getting no sound. I tried the Terminal command and kyen's app, and I could see the process happen (the icon changed to indicate no volume, but then returned to the original level), but the icon in the menu bar remained gray and inactive.

Then I plugged the speakers back in (which made the icon a nice black again, and made the controls operative) and ran the app. This time, when I unplugged the speakers, the volume controls continued to work and I had sound. If the command didn't work for you, you might want to try it again with something plugged into the headphone port.

Thanks very much to those of you who provided the Terminal script and to kyen for the app.

Hi, Today i reveived my new Mac Mini 2.7 2011 with the 6630m.

Follow the steps, including the paste in Terminal and you will all be fine !

Everything works now. Ac3, Dolby Digital, etc. In VLC and Quicktime alike !

Good luck and anjoy your minis !

Cheers,

This is much more quickly available by holding alt (also called option key) and clicking on the loudspeaker symbol in the upper right corner. I already mrntioned that - switching around the sound prefs like that resets core audio too.

I don't know if this helps, but I had some problems with my Mac Mini with poor audio quality. So I went to audio MIDI setup and chose "mute" on one of the master channels. Seemed to have worked!

Added a "multi-output device." Maybe that's "the go" as well.

But for the regular output it's 48,000.0 Hz | 2 ch-20 bit integer. But you might have to tinger it to suit your computer until you get it right. But the main thing is definitely muting one of thoe channels (in my case it was 2.)

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 😀

This did the trick for me - just for informational purposes, the issue was happening on a 13-inch, Mid 2009,

2.53 GHz Intel Core 2 Duo.

Killing that process brought back volume control.

Thanks for the tip kyen99

I just noticed taht when I go into Audio MIDI Setup, it says under Audio Output, "Output is not supported". No options. What I had been looking at before, where the volume control is greyed out next to "M", is the Audio Input side.

some more points :

- as long as the process (e.g. Toast) is scanning for drives or whatever its doing with the USB-Bus the reset doesnot work.

- sometimes it has to be done 2 or 3 times, either by switching the device or killing the coreaudio driver.

I finally found a definitive solution. At least (and hopefully) until Apple releases its official one:

Running Windows 7 on bootcamp partition.

I know, it's sad. But it's true.

😟

Last time I had a computer with no audio was on 92 or 93. It was a 486 DX2 66. And it was audioless only before I bought a Creative Labs Multimedia Kit. I've had audio ever since. At least until two months ago, when I updated to Lion.

Thanks Apple for reminding me of this nostalgic time.

Enter this on the commandline / terminal with the Lion Audio Fix so you wont have to enter the admin password anymore.

sudo chown root /Applications/LionAudioFix.app/Contents/MacOS/applet

sudo chmod 4000 /Applications/LionAudioFix.app/Contents/MacOS/applet

I have the same problem

I called apple support and they weren't able to fix it. I tried all the online solutions, still not working.

They only thing that worked was re installing lion. With it, it works!

Yet each time I reboot it comes back to 10.7.2

I am going crazy!!!!!

I have an USB-soundcard ( Logilink)

with Leopard/SnowLeopard i just Plugin and had sound and microphone on USB with Headset.

with Lion i have sound but NO Microphone! ****!

Only the built-in microphone works

I got help by the internet:

C-Media CM6206 Enabler for Mac OS X v2.1

http://www.dr-lex.be/software/cm6206.html

Iinstalled this one and got my USB-soundcard with microphone and sound working :-)

Check this for other USB soundcards, i think it works.

I was having the same problem under Snow Leopard after using Logitech USB headphones. Kyen99's LionAudioFix script worked for me, too. What would happen if I changed the file name to AudioFix? I'll never remember to look for "LionAudioFix".
