I have a Sharp Aquos Q+ with Vizio 5.1 soundbar and it is possible to connect via HDMI ARC cable. One of the HDMI inputs will do ARC audio so you can only connect to that input. On mine, it's HDMI 3 but yours may be different (TV manual should tell you which HDMI input will do ARC). Also to get DDigital and DTS, you have to change audio setting on TV to "Bitstream". When it all works, you Sharp TV will automatically switch off speakers and connect to soundbar. Thus when you raise the volume on TV, it will actually raise it on the Soundbar.
