Hi everyone! First post ever on Reddit so apologies if I don't adhere to proper etiquette :)
I moved into a new house that has a pair of ceiling speakers which I cannot seem to be able to connect to my TV system. I tried reverse engineering what this setup looks like but I am failing to crack the last piece. These are my basic ceiling speakers which are connected to a volume control unit , and the other end is misteriously connected to a wall switch. There are two wall plates that have RCA, coax and HDMI cables - but I did not manage to get sound my hooking up any input units (laptop, TV) through these cables, which I guess it also makes sense since I did not see the wall switch or volume control unit connected to anything else. I am attaching pics of every module as well as a diagram with my best interpretation of what is going on.
I did buy a cheap Digital Audio Amp with bluetooth that I hooked up directly to the input of the volume control unit and I was able to get sound coming from the speakers, so my first certainty is that they are working.
The part I cannot seem to figure out is why is the output end of the volume control unit is connected to a wall switch, especially when there doesnt seem to be anything else coming out from it - I could not trace where the cables from the wall plates are coming from, I do not have attic access which makes it a tad more challenging. I did not end up in good terms with the house seller, so reaching out to him is unfortunately not an option.
Your time is valuable, so I took pics of everything and I am also attaching a diagram with my best interpretation of the setup - any help or leads from this expert crowd would help a lot!
Let me know if I can provide any more details, thanks!
