Record Audio and Video on Linux shows black screen without audio, requires pressing "Apply" twice to work.

What is your operating system?
Arch Linux
Shotcut Version : 25.01.25-1
Installed through pacman package manager

Can you repeat the problem? If so, what are the steps?
Open other > Video4Linux with default settings


No audio, but video works

Add audio through pulse audo (or any other), click apply

No video either.
Click on Apply again

Now it works! (I found this out randomly while writing this issue)
Recording audio with “record audio” works perfectly fine.
