No audio from usb playback

[Vulcan74]

Hi,



I need some help, please



I get no sound (I get a picture) from any video I have on my usb stick when watching them on my PS5



I can watch Netflix or play games with sound from my tv or headset, not a problem.



The usb stick works in an xbox, tv, or laptop with picture and sound.



I've checked the output volume, and it's not muted, I've changed the hdmi cable and got the same problem.



I've even tried a different usb stick and a different PS5.



Still no joy.



Can anyone help?
