I am using Skype in Ubuntu 20.04. I have cochlear implants and have a Headset device connected to my audio out port. This device streams sound directly to my cochlear device which allows me to hear perfectly. This headset device is the default device for audio out in Pulse Audio on my system. When I am using Skype and click on Speakers -> Test Audio, the sound is directed to my cochlear implants correctly. However, when I click on Make a free test call the sound plays back through the USB DSP v4 Audio Interface which I use for sound input only. I cannot hear sound through this device. Is there a way use one device for Audio input and another for Audio output?
