New to this so I hope my title is accurate to my problem. Moved into a new home and there are built in speakers throughout the first level. 4 and a subwoofer in the living room, 2 in kitchen, 2 in dining room, and 2 in the office. All the speakers have wire run to a mechanical room sorta thing in the office closet. The issue is I have no clue how to get audio from the tv in living room to closet and back to speakers in living room. The only things behind the tv are 4 cat6 female ports and a coax line which run to the closet. Upon doing some research I think I can get audio from the tv to the closet through the cat 6 port using something like this: https:\/\/www.amazon.com\/H-COME-Extender-Ethernet-Transmitter-Receiver\/dp\/B076KD5LJ1\/ref=pd_aw_fbt_sccl_1\/140-2629710-0683934?pd_rd_w=ccOP1&content-id=amzn1.sym.f353d175-26fc-4776-8298-842dab47b290&pf_rd_p=f353d175-26fc-4776-8298-842dab47b290&pf_rd_r=JDR3BPKM8AKYTJ3RF0K2&pd_rd_wg=ewLCj&pd_rd_r=e0b02df8-b0b8-40ec-a690-de3440c98858&pd_rd_i=B076KD5LJ1&psc=1\n\nIt would be; tv > HDMI to Ethernet > through the Ethernet run in the wall to the closet > Ethernet to HDMI > receiver > speakers\n\nThe issue I run into is all the receivers I've seen have only a left right center while in the living room there are 4 speakers and 10 throughout the house so I won't have enough outputs on the receiver, right? I have a speaker selector, would that help? \n\nThe guy who lived here before said he never set it up bc a local audio company quoted 3000 in parts to get it to work. Is that true? Even if I had a receiver for each zone I feel like it wouldn't be that much.\n\nLooking forward to hear what you all have to say.
