Good day,
I was having a similar issue not getting any audio from any site in Chrome. I'm running Windows 11 22H2, but I didn't have any audio problems when I updated my PC in October. Issue started over a week ago. I tried multiple restarts, close and reopen tabs, mute and unmute tab, reset Chrome, use Chrome's check for harmful software tool but nothing. Checks in Volume mixer always didn't show Chrome as an app using audio. All other apps - Media Player, Edge, Spotify etc. were able to play audio and showed up in Volume mixer.
I trust that that issue was sorted out for you, but in case it wasn't or someone else is stuck at it like I've been, heading to the Settings App > Sound > Volume Mixer > Reset sound devices and volumes for all apps to the recommended defaults worked for me (at least for the time being).
