My parents are renovating their living room space and need a suggestion for a home Hi-Fi system to use for both watching movies and as a make shift karaoke machine. We've already purchased microphones and an audio interface which dont work with out existing soundbar setup.
Any suggestions?
Does the soundbar have a MIC input or a line input or a pre-amp input? Depending on the input type may be why the MIC does not work.
What are you calling an "audio interface"? Was this an adapter a 6.35mm to 3.5mm adapter?
