Query: Great, but no sound

I purchased this unit because of its reasonable price and HDMI capability. After replacing my existing receiver, I found that the front left and right channels and one of the rear channels had no output. After returning the unit and purchasing a replacement (of the same model), I am well pleased. The set up was a snap. The automatic sound balancing worked perfectly. The HDMI works flawlessly. Once I got a working unit everything is good.
