Re: [10.5] Occasional flashes to black with Dolby Vision

I just updated to 10.5.0 Build 4201-C2. When I updated my LG C9 firmware last summer I still got a break in the sound every few seconds like a scratched record. I just got a new update to my AV receiver firmware and the sound problem is now gone as well.

Be sure to check that the firmware for all your devices is up-to-date.

Roku Ultra 4800X - 10.5.0 Build 4201-C2

Denon AVR X2600H - 7400-3093-3061-3085

LG C9 - 05.10.25
