Looking for help, I have a new projector and a sound bar that I want to use together, but the projector has no audio out, and I don' want to buy a receiver and speakers at this time. can I split the source by using a 1 in 2 out HDMI converter?
You can use a splitter but only if the soundbar has an actual HDMI input rather than just an HDMI-ARC connection.
You can use an HDMI input selector with audio extraction. That will give you digital and analog audio outputs for the soundbar.
