Hi Howard, I get why this has you scratching your head. The issue usually comes down to how Phone Link handles permissions, it’s treated as a system component, so it doesn’t show up under Microphone privacy settings like other apps. That means even though your mic works everywhere else, Phone Link can’t grab it because Windows isn’t giving it the right access.
First thing I’d check is that your mic is set as both the default device and default communication device in Sound settings.
Also make sure global mic access and “Let desktop apps access your microphone” are turned on. If that looks good, try resetting Phone Link under Settings > System Components > Phone Link > Advanced Options. If it’s still acting up, we can remove and reinstall it using PowerShell.
Quick question, are you using Bluetooth for calls or sticking with the built-in mic? That helps narrow down if it’s a permissions issue or a missing audio profil.
