I recently bought a JBL headset called JBL Quantum 400 that has support software called Quantum Software. This software is only available for Windows, so I installed it using Wine (wine-5.0 (Ubuntu 5.0-3ubuntu1)) and it went well. My Ubuntu version is 20.04.1 LTS.

The thing is, Quantum Software does not detect my headset, regardless of whether I plug it with the jack or USB. I can't do any tweaks or updates on my headphone's firmware, nor can I set it to be used to its full potential.

Another thing that's going on that might have something to do with this issue is that Ubuntu does not detect the built in mic of the headset when it's plugged via USB. That is, when I go to Settings > Sound, the built in mic is not listed.

Thanks in advance for your time guys.

Have a nice day

Installiation:

sudo apt-add-repository ppa:yktooo/ppa
