My story - Sonos Amp in basement powering ceiling speakers in 2nd floor bedroom. I am looking to run analog audio out from the TV down to the basement as an input to the Sonos Amp and have the Sonos play the TV audio over the ceiling speakers.
Originally was going to buy a 100' analog RCA audio cable from monoprice (5350), clip 1 end, pull wire and terminate with right angle RCA connectors to the back of the keystone jacks. That was the plan until I saw that the cable isn't in-wall rated.
Next option is to buy a pair of the 100' monoprice HQ coax RCA CLS cables (5872) and run them same as above.
Final option is to run Cat6 riser and use MCM baluns (50-7724 & 50-7760, 50-7761). Not knowing much about baluns I tend to avoid them, for no real other reason.
My biggest concerns are that running the audio 75'-100' to the basement and back again would introduce some audio to video sync issues since the video is not taking the same path but is feeding straight from the STB over HDMI to the TV. Also that I will pick up some interfernece and the audio quality will be poor.
Any thoughts on what the better connection option would be and if I'm likely to see any sync issues?
