Lost left channel after 1.1.1 update

[TuoppiP]

I have a brand new 8GB nano. First few days it was running smoothly. After I updated it with 1.1.1 I lost the other sound channel. Could this be a version problem or it is just bad luck and faulty hardware. Anybody having the same problem?

Check your equalizer settings, and try different headphones for starters.
Also, a restore might be a good idea.
