Hi,
You can try to workaround this issue by plugging in an external device, i.e. headphones to your Windows machine. Then connect to the Windows machine via NoMachine and check if everything works as expected. I hope it will help you. I’m still trying to find out why capturing audio doesn’t work with several drivers.
Hi,
There is a way you can temporarily fix it. Our test team found that setting NoMachine Microphone Adapter as the default device fixes the issue but it shouldn’t work that way. Microphone adapter is for sending voice from the client to the server. We’re now trying to investigate why this happens on Windows.
Hi,
Try to run it in recovery mode:
1. Turn off your computer.
2. Turn on your computer in recovery mode
3. Run the command /usr/sbin/spctl kext-consent add 493C5JZAGR as before
4. Restart your computer
If you don’t know, how to start up you Mac in recovery mode, check here: https://support.apple.com/en-us/HT201255
Hello,
You can try this command:
/usr/sbin/spctl kext-consent add 493C5JZAGR
If it still doesn’t work, please send me any notifications you will get.
Hello,
You can check if NoMachine kernel extensions are in the kext policy database:
sudo sqlite3 “/var/db/SystemPolicyConfiguration/KextPolicy” “SELECT * FROM kext_policy;” | grep nomachine
Please send us the result of this command.
Also, do you use any Mobile Device Management like JAMF?
Hello,
You can update the NoMachine application to the newest version (7.8.2). Then, after the installation you should see the notification about blocked extensions. Enter the Security & Privacy as before, click the lock to make changes and allow system software from NoMachine. Please note that the possibility to unblock the loading of NoMachine system extensions is available only for 30 minutes after the system has issued the ‘System Extension Blocked’ dialog.
Hello,
You can check the kernel or system logs with this command:
tail -f /var/log/system.log
tail -f /var/log/kernel.log
You can also use the ‘less’ command, for example:
less /var/log/kernel.log
Hi,
First, in System preferences -> Security -> General Tab in section “Allow apps downloaded from” check if the option “App store and identified developers” is marked.
Then, please run this command:
sudo kextload -vvv /System/Library/Extensions/nxaudio.kext
Then you should be able to see the notifications about blocked software in System Preferences->Security->General Tab. Please allow loading system software from NoMachine S.a.r.l.. Then probably you will have to restart your machine or at least NoMachine server. You can find more information here: https://knowledgebase.nomachine.com/AR01P00962
Hi,
Try this. After running the command “sudo kextutil -vvv /System/Library/Extensions/nxaudio.kext” access System Preferences -> Security&Privacy -> General panel and click on the “Allow” button.
Hello,
Please check if you see NoMachine Audio Adapter in your audio settings while the session is running.
If you don’t, please check if you can load nxaudio.kext by running the following command:
sudo kextutil -vvv /System/Library/Extensions/nxaudio.kext/
You can check the result by running:
kextstat | grep nxau
The output should look similar to this:
265 0 0xffffff7f83cd6000 0x5000 0x5000 com.nomachine.driver.nxau (4.1.b2) 78172556-B6A4-3112-BA41-E79D18108476
Then restart NoMachine server:
sudo /etc/NX/nxserver –restartKuba
Hello,
I would like to know some details in order to help you:
* the version of Windows you use
* please check if Audio Service is running or not
* You wrote that you can’t change the default output. Do you mean there are no other options available besides NM Audio Adapter or maybe there are but you can’t choose them? Or you can choose other options but they don’t work?
