What is your Shotcut version (see Help > About Shotcut)?
Shotcut version 22.12.22
Can you repeat the problem? If so, what are the steps?
How do I set microphone input properly? From what I saw in the tutorials there should be Audio/Video option under Device but it is not there. I tried restarting Shotcut but it didn’t work. The microphone shows up properly in my Linux OS mixer and it works properly when recording sound and talking thru discord.
That is only on windows and macOS. On Linux it is what you see in your screenshot: Pulse, JACK, or ALSA. PulseAudio is what most people are using. In that case, it uses the default input, and you use the system settings to set the default input.
