Question No audio coming from speakers connected to projector from specific files

[PJGuy]

Hello, i have speakers connected to a projector via an aux cord, but i cannot hear any audio from my movies. What's weird fom me is that other files that are not movies (like videos taken with cellphones) play flawlessly. All files are on and SD card directely inserted in the projector, since connecting an HDMI to a laptop is not ideal for position reasons. Still, I tried usind an HDMI and audio was working fine. Am I right to assume the problem is that the projector's software does not elaborate certain types of audio, for example AC-3 at 384kb/s? I also tried with a usb hard drive, and encountered the same problem.

The projector is a bomaker

You mean "can't", right? Thank you, I thought the same, I'll try to convert the audio track, maybe with handbrake..any suggestion is appreciated!
