Have Roku 4, when using iphone for remote listening Via bluetooth earbud, I can’t seem to adjust the volume. When I press volume buttons on right side of remote, a bar pops up on screen showing 100%, but nothing changes when I press the volume control. Any help will be appreciated. Thanks.
I have to say that I've never used the app for listening, instead using the jack in the remote. But I would have my doubts that the remote volume control would have any effect on an external listening device. The volume buttons will control the audio from the remote jack, and via CEC can control the TV or AVR volume. I don't believe the 4 remote has the ability to IR control anything, so I don't know of any way for the remote to control the volume on your phone.
