Using pavucontrol, I can see:
Playback: NoMachine: NoMachine on [Null Output] *
Recording: NoMachine: NoMachine from [Monitor of Plantronic USB Analog Stereo]
Output Devices: – Plantronics .Audio USB Analog Stereo
– Built-in Audio Analog Stereo
– Null Output *
Input devices:
– Plantronics .Audio USB Analog Stereo
– Built-in Audio Analog Stereo
* – the VUmeter show activity when speaking into the headphone mic on the laptop
So it seems the laptop mic is redirected to the server… I just don’t know how to connect it to KVM. Also I though this would be somehow automatic – I can’t reconfigure KVM each time I change seat. Is there a way to create some fake recording device that would once be connected to my laptop’s mic and at other times locally?
