Volume control with Airplay

I’m using ipad pro 10.5 with infuse 6.5.7 (latest)
When I use airplay to stream sound to my speaker,
gesture control on right side of screen is not available. (But, if I play the video and sound on iPad, gesture control of volume by dragging the right side of the screen to upward/downward is possible)
Is there any way to control the volume in infuse when I use airplay?

(I modified version number)

Welcome to the forum!

First thing would be to update your copy of Infuse to 6.5.7 which is the most current version. There may have been several changes to the audio portions since version 6.0.

I modified the version number. I’m using latest version.
