I have a kitchen/family room. I have installed 2 ceiling speakers, and have got an amp to power them (I bought both Sonos amp and ceilings speakers new Nov 2022).

I also have a gen 1 soundbar and a gen 3 subwoofer. 

i want to use all this in 2 ways:

Watching TV

Soundbar gen 1 connect to TV via optical, and want to use the sub and use the 2 ceiling speakers as surrounds.

Listening to music

Use the amp and 2 ceiling speaker along with the sub. (If the soundbar could be used in this set up, this would be great, but not essential)

I want to know 1) is this possible? And 2) what way do I go about configuring this setup to work with my 2 use cases.

Thanks in advance
