No microphone input on Ubuntu LTS 24.04.1

[DaPieDude]

– Free NoMachine 8.14.2

– Connecting to a virtual display

– Client is Windows 11

– Host is Ubuntu 24.04.1 LTS Noble using GDM3 as my desktop

 

My microphone input isn’t working. The “NoMachine Audio” device when selected as an output speaker works as a speaker. The “NoMachine Output” device when selected as an output speaker doesn’t work as a speaker but I can see it detecting my voice. The “Remapped_NoMachine_Output_Monitor” is the only selectable input device and that does not pick up my voice.

Hi,

For your information:

– NoMachine Audio is a virtual speaker, so it’s okay that it set as default.

– NoMachine Output is created as a speaker but it’s used for processing voice data.

– Remapped NoMachine Output Monitor is a remapped source of NoMachine Output and it serves as a microphone for the user. It has to be this way in order to collect and transfer voice data properly. It’s okay that it’s the only selectable microphone in the virtual session

Now, in order to enable voice recording inside a NoMachine session, you need to click up-right corner of the session window to open the session settings. Then go to “Mic in” and click “Enable mic”. At this point voice recording should work.

If you did this step and voice recording doesn’t work for you, we will investigate further.

Regards,

Kuba
