Our Sonos is connected to the TV via IR cable. When we turn on the sound to the whole system it starts cutting out and gets choppy. When it is just the sound bar there is no issue. Ive replaced the IR cable, reset the Sonos, and reset the actual soundbar.

I’d be checking the audio settings on the TV, and all devices that feed the TV, to ensure that the feed they are providing is, at most, a Dolby Digital signal. Anything that is set to ‘auto’ would have the potential to send something ‘higher’, that would not be capable of being sent across the optical cable.
I would also submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
