I've searched and googled regarding this issue but couldn't find anything helpful.

I got a new S23 a few days ago and I quickly noticed that even with sound turned on, with all volume meters turned up, my system sounds just won't play aloud until I either connect earbuds to the phone or if I play some kind of music, video, etc. first.

When the video/music/etc is playing, or if my buds are connected, I can then hear all system sounds fine, like pressing the back/home button, keytaps on the keyboard, notification sounds, etc. It works like normal. The sounds are clear when they're working so it's not a "system sounds are just very quiet" issue (at least I don't think so?)

Without the video/music/some kind of audio feedback playing, all of my system sounds just completely stop playing aloud and it's like I may as well just be on mute.

Does anyone know what could be causing this, am I just missing something simple? I've also fully updated my phone to the latest updates so I don't think it's that.

Also, not sure if this is helpful or relevant, but I also noticed my vibration doesn't work at all, not even when running diagnostic tests :/
