I've tried everything. I tried the optical port, aux (I really need the AUX to work for what I need), and HDMI. I connected the AUX to the sound bar (AUX IN) then to my PC (AUX OUT) and no sound. I've even gone as far as trying AUX via sound bar/monitor and no sound. I've tried connecting my phone via bluetooth and it connects, I can control the sound bar.... but no sound. No it's not muted, and the (included) subwoofer connects correctly. This is severely frustrating after a $300 purchase and hours of tedious troubleshooting. Anyone that may have some insight please let me know, and thank you very much.
