I just upgraded from an old Pioneer, non-hdmi receiver and attempted to hook up my Polk Audio RM75 (just front and center speakers), and I am getting either low or no volume from my various input hdmi sources. I verified that the sources are not limiting the volume output.
I did do the speaker and Audyssey setup. During the test, the speakers did play nice and loud.
Sometimes when watching tv, the show will have no audio, but then a commercial will...
How can I ensure that my DirecTv, PC and Xbox 360 all sound correct over just 3 speakers?
