I can confirm. I've been helping testing with @eNerGy72 and neither him can listen me or see my talking icon or I can si his. We've been diagnosing the system and everything seems right. I've been talking with him over Discord when it failed. Funny thing, his test voice bars in mic testing, inside PUBG setup, seem to work and detect his voice.
Testing the common shortcuts for enable / disable voice chat, mute, etc. failed too.
I have been using the voice chat with other players the same session without issues.
