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)

Last few days things seemed to have reverted back to normal behaviour, I am now getting normal sound balance after redocking.
I don’t remember any significant updates from Apple in the last week or so. I did however take my laptop on holiday, switching off power completely for my Cinema Display. After coming back things now seem normal so this may have contributed to the resolution. May be worth a shot if you had similar issue.
