My 2.9.0 Roku app (on Roku 4400X 9.0.0) doesn’t honor the “surround sound” setting on recent recordings. Even when that setting is “off”, it refuses to play when I’m using the private listening feature because that doesn’t support surround.
This problem seems to be specific to recordings made with the latest Tablo firmware (2.2.26). Older recordings play fine. This is with the classic 4-tuner Tablo.
