Audio OFTEN goes missing ONLY when trying to play surround sound.
Audio OFTEN goes missing ONLY when trying to play surround sound (when I set ROKU audio setting, both "AUDIO" and HDMI" settings are set to AUTO).
When the audio gone missing, it will be missing for all contents (Youtube, Netflix etc) and I have to restart the ROKU to get the sound back.
As indicated in ROKU troubleshooting guide, this problem indeed will go away when i changed both "AUDIO" and HDMI" settings are set to STEREO, however this solution is not acceptable since I won't able to benefit from the Surround Sound.
I am using Samsung QR90R Soundbar which support Dolby Digital Plus and Dolby Atmos.
And I am using Belkin latest HDMI cable to connect my Roku Ultra to the Soundbar.
FYI I encountered the same problem when I tried with the TV Speakers also.
In addition to ROKU Ultra, I also have Apple TV 4K and I can enjoy Dolby Atmos on my Soundbar with it.
Kindly help to look into this problem and advise me accordingly.
