Can't join to the voice chat

[Dark]

So, after pressing "P" ingame, it always shows that I muted myself, I can use chat, but can't use or hear anyone speaking, it auto mutes me when I try to unmute myself.

Anyone knows how to fix it?

I have this exact same issue. I've never had the issue before and I've tried playing the game on both Steam and Battle.net in-case it was a launcher thing.

I've scoured the internet for answers but they all either aren't the same issue, or tell you to check your windows audio settings, even though that isn't at all the issue I'm facing.

Nothing really helps. I even reinstalled the windows and still the same.

I've managed to fix my issue, I tried a couple things;

I disabled any anti-virus firewall and used the default Windows Defender firewall. (doubt this was the culprit as I have used this particular anti-virus for years with no issues)

I removed any manually set DNS server in my Windows network settings, vise-versa you could try a few manual ones to see if that fixes the issue. (some things like Steam started loading way faster so I feel like this may have been the culprit)

May not fix your issue, but it's worth a shot.
