Thanks for sharing this post. One week ago, I was looking for help to fix SermonAudio channel's issue of Roku Premier+. I was facing delay on the audio issue, whenever I was played any video the sound has come after one or two seconds. Then I contacted with Roku technician. They provided some guidelines for the audio setting and I followed it. Now, my device issue is fixed. If you have same issues, you can also take help of the technician.
