Question Setup help - receiver and sound bar?

Feb 10, 2024
I have a LG UQ8000AUB that works well with my Yamaha YAS-209BL sound bar. My cable box uses the HDMI 1 and the sound bar uses HDMI 2/ARC. The issue is my kids want to play games (Wii, Xbox ,etc) on the tv and there isn't a third HDMI port. I do have an old Yamaha TSR-5830 that could expand the inputs but I don't know how to connect the soundbar to the receiver? Is there a better option that won't cost me a lot? Thanks!
