I have had my Roku Ultra for more than a year. It is working great with a Samsung TV and Auvio sound bar. However, only certain channels can communicate with the Auvio sound bar.
Works with sound bar: Netflix, Hulu, YouTube
Doesn't work: HBO MAX, Roku Channel
When I try to play a selection from the second group of channels, the sound bar gives a loud static sound and then occasional static after that. Otherwise, silence. The movie plays on video, but no sound.
I had this problem previously with a new Blu-Ray player I just bought a few months ago. I was able to resolve it by changing the encoding type setting on the Blu-Ray. I changed the Dolby Audio setting from Bitstream to PCM and the DTS/DTS-HD setting from PCM to Bitstream. Sound started working great through the sound bar.
Any ideas? This seems so strange that different channels would use different encoding schemes.
Thank you! No one thanks to Roku. It would be nice of they'd use some of their money for customer support. I'm watching HBO this second when I seen your post. I hope this works for my family too! Great work my friend!
