My friends Audio issues

So my friends audio only works about half the time. Sometimes we will be able to hear them and sometimes they wont hear anything at all and we cant hear anything from them either. They can hear world audio fine, but not other people talking. We have looked at the settings and all sliders and what not were fine, mic was connected, headphones are connected, but still no audio. Their safety settings are also set to allow them to hear people. This happens randomly and we have no idea on how to fix it. If someone might know, please tell me. Thanks.

Is this on quest or PC? Over on PC VRChat recently fixed an issue where I’d have to select the microphone every time I log in, even though VRChat shows the correct device being used

I will see if this works for them, thanks
