Good afternoon. Last night, I noticed low voice audio and louder background/sound effects on my new Hisense 4K 43" Model 43R7 when watching a movie through my Plex server. I don't know if that is tied into the problem being discussed here, but I thought I would put in my two cents worth.
Shawn, you asked for this information:
1. Roku Brand Name: Hisense
2. Model: 43R7
3. Device ID: 9K483L829829
4. My Roku Account Information: [personal information removed]
I hope this information helps you in resolving this issue.
