SONY HT A9 ROKU REMOTE NOT VISIBLE

I have the HT A9, LG G3, and ROKU ULTRA 2022. The Roku is connected to the Sony HT A9 connected to the LG G3. The problem is when using the Roku remote the volume bar does appear on screen. Also even if I use the Sony HT a9 remote when using the TV HDMI is no volume bar on the screen. The only time you see the volume bar when using the Sony remote is when the Roku Ultra is in use. Can anyone help solve this problem?
