I have a Roku Ultra and an Apple TV-4 connected to a Bose 5.1 system via an hdmi cable. When I stream music using Plex the Apple TV-4 sounds perfect however when I use the Roku the sound is dull and lackluster. Does anyone know how I can correct the poor sound quality of the Roku? Many thanks.
Could you put some of your MP3s on a USB stick and play them directly from the Roku with the Media Player? This would eliminate Plex as the culprit. I'm not sure why Plex is transcoding them, as I would expect the Roku to play standard MP3s without an issue. I believe I've tried some MP3 files with Roku Media Player, using my DLNA server to stream them. I don't recall them needing to be transcoded.
