Can´t run xibo player without sound on windows 7

im trying to run xibo player without sound on windows but doesn’t work without sound.
Try manu things like remove sound on time line on display set and windows settings xibo player.
Any body have an idea?

What CMS and player version are you using please?

What items do you have on your layout that play sound?
If you have for example videos with sound you can mute them in layout designer.
