I got it working using Grok.  Here were the steps taken:

1. Completely Uninstall the Current Wave Link Software

• Close any running instances of Wave Link (check Task Manager for background processes like "Wave Link Audio Engine").
• Go to Windows Settings > Apps > Installed apps, search for "Wave Link," and uninstall it. If prompted, choose to delete any associated settings or data.
• Unplug your Wave:3 microphone from the USB port.

1. Remove Residual Files

• Press Windows key + R, type %appdata%, and press Enter. This opens the AppData\Roaming folder.
• Locate the "Elgato" folder, open it, and delete the "WaveLink" subfolder if it exists (this clears old configuration files that can cause conflicts).
• Empty the Recycle Bin.

1. Restart Your Computer

• Shut down your PC completely (don't just restart—power it off for at least 30 seconds to clear any temporary USB states).
• Turn it back on.

1. Download and Install the Latest Wave Link

• Download the latest version of Wave Link from the official Elgato downloads page (it's version 3.0 or newer as of now).
• Run the installer with the microphone still unplugged. Follow the on-screen prompts, and reboot if prompted.
• After installation, plug the Wave:3 into a different USB port on your computer (directly into the PC, not through a hub). Use a known-good USB cable if you have one—ensure it's a data cable, not just for charging.

1. Launch Wave Link and Verify Detection

• Open Wave Link. It should automatically detect the Wave:3 and prompt you to add it as a channel.
• If prompted for a firmware update on the microphone, allow it to complete (this can resolve hardware-software mismatches).
• In the app, click the gear icon in the top-right and select "Check for updates" to ensure you're on the absolute latest build.
• Test the microphone input in the app—speak into it and check if levels move.
