Would this receiver work with this setup or something similar?
Or are there other solutions that would work with these devices (TV and Turntable)?
And are there any disadvantages to using a receiver with these devices and Sonos Soundbar (latency or anything else?)

#1 - you could get a Sonos Connect to hook the turntable/mixer to - thus making it a part of Sonos system
#2 - you could convert the turntable RCA audio from Mixer audio to optical output like the tv

#3 - get a Sonos Play:5 - this will give you an analog input to hook the RCA/Mixer to and also give you the advantage of another Sonos speaker that can play from the turntable in addition to the Playbar.
Personally - I would get a Play:5. Great speaker and allows you to input your turntable and play on any Sonos speaker in your house including the Playbar.
