On the Scarlett USB interfaces, the green/red LED ring around the input gain knob is driven directly by the hardware. Pulseaudio has no influence over this. So if you're not seeing any signal there, the issue is in hardware. Make sure: - The XLR cable is OK and fully seated into the plugs on both ends. - The switch on the side of the mic is on. It needs to be on to feed output to the XLR jack. - The preamp gain knob on the Scarlett is set high enough. Dynamic mics can have pretty weak signals. On mine, I need to pretty much max out the preamp to get signals strong enough to light up the green ring.
Sean, Thanks very much. I probably had the gain too low. Stay well, Rich
