As stated earlier, one of the weakness of Popsical is that the audio out is only via RCA connects. My LG soundbar dont have RCA sound in (only has Optical In), and I believe many newer soundbars also don't have RCA socket. I plugged my Remix RCA to an old home theatre amp/speaker system.
Its better to use the Remix with a decent sound system. Make sure it can accept RCA connects. Most would - Aux socket.
I forgot to mention that one can buy a RCA analog to optical digital converter to overcome the RCA connect issue. However these are not easily available as most converter is digital to analog.
