I will probable stream music through a streamer when I am listening to music
I currently do this. I have the TV coming in to the DAC via optical and on old W4S modified SONOS ZP90 coming into the DAC via coax. The SONOS is a ROON endpoint. You just have to configure your AV unit with the correct inputs to handle it all. Nice to have a DAC that has various digital ins. AV config is a PIA.
One thing I have noticed is when the TV is going through the DAC is I have to turn up the volume more on the AV unit but once I do that is sounds much better.
Edit: My AV set up is simple 3.1. I dont use any of the new fancy formats.
