Push to talk issues

[anthrax2471]

Hey dudes, currently using 27.2.4 with no issues, as soon as I update my PTT starts playing up. For eg I'll push the button to talk but my mic won't activate sometimes, I've even tried the 29 Beta to no avail, I have no other issues currently so a log is pointless as other people are experiencing the same thing.

Any help would be highly appreciated

Thank you.
