In game voice chat issue

Hello, as of a couple of weeks ago, my in-game voice chat has stopped working, group, team and match chat do not work. I have run through the troubleshooter on this topic a dozen times and it doesn’t fix this issue, i have tried every variation of push to talk, open chat, different inputs etc, all the hardware works on every other format, including the voice chat settings in the battle.net launcher. The only thing i get when i enter voice chat and press to push to talk is a little bleep when i push the button. For clarification, i have never received an error message or been notified of a chat ban (i very rarely use voice chat anyway so this doesn’t present as a possible issue to me) additionally I can always hear others and going back 2 or 3 weeks, I had no issues in this field at all.
Thank you in advance
