Hi, I have a slightly older tv Samsung LE37A336J1D and a Panasonic SA-PT580 Surround Sound System. I also have an Amazon Firefox Stick and have just purchased an August DVB400 Freeview box. I don't have enough HDMI slots for all of these products. The Amazon stick doesn't work with the surround sound. Is there a product on the market that can act as a go between for all of these products? Help please?
