I have the HDMI cable in both ARC ports for the tv and receiver but no sound
First, some AVRs have more than one HDMI output jack, but only one supports ARC, so make sure you're in the correct one there. I can't recall exactly what is in a Roku TV audio settings (the only TV I have is in full time use as a computer monitor by my daughter) but you usually need to select where the audio output goes (speakers, optical, HDMI/ARC, etc.) I don't have a Sony AVR, but I seem to recall that my Yamahas have a setting to enable ARC as well, so check the settings on both devices.
Try refreshing the cec devices in the Roku tv settings.
Settings> system> control other devices> search cec devices> follow prompts
The hdmi is plugged into the ARC on both
I’ve turned on the hdmi port on the AVR and I’ve set the audio on the tv to ARC 1
so far no sound
Did try the steps in my post? You last post didn't mention cec, so you might not have seen my post at all?
Yep
I did everything you said to do and still getting no sound
On ARC HDMI it says inactive but I have the port checked ON
