Just got a new 2019 model Roku Ultra, and I noticed that the audio volume from the Tablo had gone up. Assuming that Tablo finally fixed their long-time problem with having lower audio level than everything else that I stream, I looked at the firmware version on the Tablo. Hmmm…that hadn’t changed. Finally figured out that the Roku “volume leveling” brings the Tablo up to the audio level of everything else. Apparently came with a recent update of Roku, just hadn’t noticed that. Good job, Roku.
So another Tablo problem solved by someone else. Fine by me, now I don’t have to turn up the TV volume to use the Tablo and turn it down before using any other app on the Roku.
