I was not able to find anything similar to this, so I hope this is not a duplicated question...

I have the following issue with my Elgato Wave 3 microphone: when I want to use it as an input (microphone), it works like a charm, but when I connect the headphones at the back of it, using it also as an output (selecting it on settings panel or PulseAudio control), the microphone stops registering as an input, so I cannot use it anymore as a microphone, but headphones works...

I saw that it could have missing the output + input or duplex profile or something related to the profile, but I have no idea if I can add it or what can I do to solve this. I tried researching about pactl but I do not understand it fully.

The profiles I see are:

1. Analog Stereo Output


2. Digital Stereo (IEC958) Output


3. Analog Mono Input


4. Off

Thank you !
