Cannot change the sound volume when I connected ipad with an AAXA M6 projector to play YouTube

As the title, I encountered an issue when I connected ipad with aaxa m6 to play youtube videos. The sound choice on ipad seemed half way but locked. I cannot change it at all. Though I turned up the projector to its maximum, the sound was still not loud enough. Any solution for it?

Thanks anyway. Tho I cannot find a solution for this problem either, I tried another video, which had larger original volume. It sounded fine. I have to admit the built-in projector speaker outperformed my expectation. But I am just uncomfortable when I know there is an issue, but I cannot tackle it.
