/vr/ - Retro Games

Hello, I'm new here and it's my first time trying to set up a CRT. I've tried connecting my ps4, switch and pc on my philips 14pt1482 but I'm not getting any audio. I'm using a cheap hdmi to rca converter I found online with stereo output, my tv only has mono. The video seems to be working fine but I'm not getting any audio even after trying a Y splitter, or just connecting the white one. The speakers do work but I'm not sure if there's a problem with my audio port or my setup is just wrong. I don't mind buying it another speaker but I'd rather not if I actually don't have to.
