I have the same issue.
I just purchased a brand new Roku Ultra LT (4801RW) and after the firmware update (12.5.0 Build 4178-DE) I can't get any sound out of my soundbar (Yamaha) that is connected through an HDMI Arc port on the TV.
I connected the 4801RW to another TV that didn't have a soundbar and just had the speakers in the TV and the sound worked fine.
I was using a Roku 4670X, so I re-installed it on the TV with the ARC HDMI soundbar and it is working fine. The Roku 4870X is using Firmware 12.5.0 Build 4178-46.
So it appears to be some sort of bug with the latest 12.5.0 firmware version on the 4801RW.
I'll wait a little while to see if Roku comes out with a fix.
