After installing the NoMachine client on my Mac, I’m not seeing any audio devices listed under the sound output preference pane.
I’m unable to select any NoMachine audio device. I’ve tried to uninstall/reinstall and even tried the latest build available but the same results.July 16, 2021 at 13:41 #34502CarinParticipant
Did you approve kernel extensions as explained in this article? https://knowledgebase.nomachine.com/AR01P00962
If not, please do it and let me know the outcome. Thanks!July 22, 2021 at 20:17 #34557
I’ve tried to reinstall the application, but I’m not getting the prompt to approve the kernel extensions.
Is there a way to force that to happen again?July 23, 2021 at 12:30 #34566BritgirlKeymaster
Try going to Microphone permissions (both client and server sides), uncheck and check NoMachine but on both hosts
– restart player on client side
– restart NoMachine server on server side
Does this help?July 23, 2021 at 17:36 #34569
I reset the permissions on both sides, but the server still does not list NoMachine as an available hardware device.July 26, 2021 at 13:37 #34576tsotneParticipant
1. let’s load nxaudio kext manually:
sudo kextutil -vvv /System/Library/Extensions/nxaudio.kext/
2. if you did not approve it, do::
Access System Preferences -> Security&Privacy -> General panel. Click on the “Allow” button
3. if it finished without any error, check if it’s loaded properly:
kextstat | grep nxau
you should get similar output:
180 0 0xffffff7f83d9c000 0x5000 0x5000 com.nomachine.driver.nxau (4.1.b2) 78172556-B6A4-3112-BA41-E79D18108476 <93 6 5 3 1>
4. restart NoMachine server:
sudo /etc/NX/nxserver --restart
If audio still does not work, please send us the output of kextutil command (point 1) in your reply.July 26, 2021 at 17:00 #34582
After loading the nxaudio kext, it never prompts to allow permission in security.

Defaulting to kernel file ‘/System/Library/Kernels/kernel’
/System/Library/Extensions/nxaudio.kext appears to be loadable (not including linkage for on-disk libraries).
/System/Library/Extensions/nxaudio.kext successfully loaded (or already loaded).July 27, 2021 at 16:34 #34591tsotneParticipant
kextstat output shows that it is loaded also, kextutil output would be different if you didn’t approve it, so you have done it already.
You should have 2 NoMachine audio device.
Can you attach audio MIDI setup’s screens (during the session, while you are connected to your mac)?
