I'm trying to get a sound bar to work with an LG TV that doesn't have any audio outs. We bought a HDMI switcher with an audio out thinking I could get that to work but no luck. According to a thread on here it should but I don't know if I'm missing something?? I ran an HDMI out of the switcher into the tv and then an optical cable from switcher to the soundbar per the instructions in manual but I'm not getting anything.
