How to Listen to Audio Input from a Capture Card on Garuda Linux?

Have you checked if your audio settings allow for 'monitoring' the input? Open up `pavucontrol`, find your capture card in the 'Input Devices' tab, and see if there’s a 'Monitor of' option available. That way, you can hear exactly what’s coming through the capture card. If it’s not visible, you might need to adjust some settings in your audio configuration or install additional packages that support virtualization of audio.

First, make sure your capture card is properly recognized in the system. You mentioned seeing it as an input device, so that's a good start! To play audio from the capture card back through your speakers or headphones, you can use a tool like PulseAudio. You’ll want to use `pavucontrol`, which is a user-friendly interface to manage audio streams. After installing it, you can launch it, and in the 'Recording' tab, look for your capture card. Then, in the 'Playback' tab, you should be able to set your output device to hear the input sound. Give that a try!
