Ok...SIRIUSLY now, does anyone have any idea why this is happening? I downloaded SiriusMac, installed it, used the login screen and entered in the captcha code. It opens up, I can see all the channels offered online, I can select any of the channels I want but there is just one problem. Nothing happens. It displays the name of the Band and song but no sound comes out. I have moved the volume up and down of both the SiriusMac player and my iMac and nothing. Not a note. Can anyone provide insight as to what I'm missing here?
