If you find that your keybinds for Whispers, Broadcasting, Push to Talk are not working as expected or not working at all within the voice channels, it's likely to be a permission within your firewall, more specifically Windows Defender.
Head over to your Firewall & Network protection within the Windows Security section on Windows and select "Allow an app through the firewall."
Navigate to Guilded and if the box that is highlighted is unselected, click Change settings at the top, which will then allow you to select that option.
Refresh the Guilded Desktop App, and your keybinds should now be working as expected.
