I have a Vizio HD TV that has only one HDMI port. Curently the cable goes directly to the HDMI. I want to get a sound bar and BluRay (with Wi fi ) both with HDMI. I can get a splitter which obviously allows me to switch between the Cable and BluRay but how can that work with the sound bar since we would want it on no matter whether we have the cable or BluRay I could use an optical connection but then I'd lose some of the BluRay definition (hard of hearing, need all the help I can get!). Any ideas would be appreciated. DPM
