Vga crt with no speakers.

I picked up this nec accusync 50 for free when they were cleaning things out at my work. It has no speakers i assume and it only has a vga port. Am i out of luck if i want to get a sound output while connecting to this? Other than a pc which i can just put speakers on the pc i cant seem to figure out a way to do it with composite cables to say a ps2 or gamecube. Im currently running a cheap av2vga converter from temu that costs 4 bones but i didnt think about the no sound problem until i plugged it in. Thanks.
