Redirecting the speaker sound from remote to local would work using WTS access but not the mic redirection, if that's what you're asking.
My executive team are asking for mic redirection on Pulse Secure Windows Terminal Sessions too as we use MS Teams on our Terminal Sessions, this would be really useful.
Are there any plans to add mic redirection, is it due in any upcoming releases or is there a way to make a feature request please?
We included Mic support in our latest release for WTS, PCS version 9.1R9
Hope this helps!
