I have a new 2020 tv that only allows audio out by optical, Bluetooth and HDMI. I have “in ceiling” speakers which are wired and are powered into a jack into the wall and then have RCA cables that were attached to the old tv. I tried using a digital to analog converter which worked but would not allow me to adjust the sound. The sound coming out of my 50” LG tv is fixed and has no adjustment in the tv for variable output. I have a 2009 Nuvo home audio system that these speakers are also wired to in another room. Anyways, is there a way to control the sound if I buy a new receiver to send the sound from my tv to and then out my ceiling speakers? This way I could control it through my receiver? Please advise.
