Balance Lock Works Great

I was listening to some music through my Skullcandy Uproar Wireless headphones, and one time I thought that the center (usually the singer's voice) had shifted to the left. I thought it was my hearing, but I thought I'd check the Mac's "Sound" balance setting...and it had shifted to the left. I manually changed it back to the center position, but a few days later, when I was listening through those headphones again, it seemed like the balance was off...and, once again, the balance setting had shifted to the left. I then Googled the problem and found Balance Lock. I installed it, and for a test, I manually changed the balance setting from the center, and Balance Lock automatically shifted the balance back to the center. This is a really, really great product! Thank you for creating and offering it!

Great idea, but

It seems to only allow centering. I want it to let me pick it to go all to the left ear as I am deaf in my right ear and I need silence in my right ear to avoid dialing up my tinnitus. I also need this to work only for specific headsets as some devices I don't want forced to all left. I only find out the inteface it back to centered when I start to get fatiged from the tinnitus and check the settings.

I am not going to use this app becuase it does not meet my needs but I am giving it 5 stars because the developer is fighting a good fight on implementing things to fix Apple's short comings.

Great solution to a problem which should not exist

I once spent a good couple of hours trying to determine why I had no audio on the left channel of my stereo. I checked cables. I checked speakers. I very nearly came to the conclusion my amplifier was broken. Once I realized that my mac likes to let the balance controls drift until I only have audio in one channel, I was a bit peeved. This is a really silly bug.

The good news is, this application keeps the balance set where you want it. An excellent workaround.
