I recently bought the Roku Streambar along with the Roku TV wireless speakers for my hearing impaired father. I have found that setting the Audio settings to Levelling, Clear Diaolog, and Music (disabling surround sound and forcing stereo) really helps him. However I wish this could be a system wide setting under accessibility to set all sound/speakers to mono.
