Elgato Wave 3 only as input or output but not both

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 !

Solution 1:

I had the same issue. Solved this and tested through Zoom recordings.

Currently on Pop Os - 20.10 Using Generic Pulse Mixer

1. Open Pulse Audio Volume Mixer
2. Go to Configuration Tab
3. Elgato Wave 3 device DropSelect -> "Analog Stereo Output + Multichannel Input"
4. Input Devices Tab > Elgato Wave 3 Multichannel -> Port: Select Multichannel Input
5. Output Tab > Elgato Wave:3 Analog Stereo -> Port: Analog Output.
6. Adjust controls physical on the device to suit input gain, output and Crossover to taste.

You may need to select "Show : All devices" if not showing up the first time, at the bottom of the mixer window.

You may need to restart Pulse Audio via the terminal with

systemctl --user restart pulseaudio.service

If your device is not seen.

Have a test call and record it. Hope it helps others.
