Q: Sound balance reverting to right channel

I have a 2011 Macbook Air that I connect to a nonThunderbolt 27" Cinema Display via the Thunderbolt/USB ports from my Macbook Air.

 

Lately I've noticed that when I disconnect the Macbook and reconnect to the Cinema Display, the sound then comes from the right speaker only. Looking into system preferences the sound balance always reverts to the right channel only. I'm choosing the LED Cinema Display device for sound output.

 

No matter how many times I then correct this, the process repeats itself every time I disconnect and reconnect, I have to manually correct the sound balance.

 

Anyone else experienced similar?

MacBook Air, OS X Mountain Lion (10.8.2)

    About sound balance reverting to the left speaker :  I notice i only happens when I listen to music videos in Youtube. It is an annoyng thing to have to go to preferences<sound<balance every time it happens. And it appears to be an randomic behavior in my Mac Pro. I can imagine that Apple should pay more attention on it. Thx and sorry for my bad writing in English, I am brazilian.

    Same for me - glad to see it isn't just my system.  Frustrating.  Why can't Apple stay on top of this stuff.  It's a pretty old bug.

    Same for left channel on mid-2011 13 inch macbook air.  There doesn't seem to be anything in particular that triggers the problem but it is persistent.

    My MacBook Pro unexpectedly shifts all sound to the left.

     

    It only happens once a month or so. I can't identify any kind of cause or solution. I just submitted a bug report to Apple about it.

    Did anyone find a solution for this problem?

     

    I have my Bose sound system plugged into the headphone socket on the front of my mid 2012 Mac Pro but everytime I boot it up the sound defaults to the right speaker every time.

    This problem bugged for me ages, then about three months ago it just disappeared.  So I never found the how to solve the problem, but it's gone now.  No changes to my MacBook Pro, just the regular updates.

    How strange. I'm up to date but I've had the problem for a while now. I hope mine sorts itself out one day too.

    Here is the solution for anyone still having audio panning trouble.

    1 Trash the com.apple.audio.AudioMIDISetup.plist and Audio Folder contents in /Library/Preferences/Audio

    2 Empty the Trash

    3 Go to Applications/Utilities/Audio MIDI Setup and balance the volume

    4 Go to System Preferences/Sound/ and reset the balance to the centre

    5 Restart

    try resetting the PRAM

     

    1 shut down your mac

    2 hold command, alt and the letters P and R

    3 power your mac on but keep the keys held down

    4 wait until your mac restarts again which youll hear the second chime sound

    5 let go of the keys

     

    let us know if it works
