netflix box

My box gives very poor sound through my sound system. Can't understand it half the time. My sound from the TV jacks are much better, Just using a 2 ch system with no computers. Should I get a better box or what?

Using and enjoying the Model 1 which has anolog rca outputs as well as an hdmi out. No issues at all. The advantage of the rca output, can turn the tv off and still listen. The hdmi goes to to the tv and a dolby digital decoder then the int. amp. I can hear the sound quality difference between the decoder and the rca outputs. Awesome little unit. 
I have the Roku model 1.
