Hi,

Does this problem also appear when iPhone X is the only client of the Server? Do you use, with iPhone, any additional Bluetooth devices to playback audio like speaker/headphones?

[mkub]

Hi,

This is not the problem created directly by NoMachine. On the contrary, PulseAudio needs client.conf file to work properly. Use this template to recreate it https://github.com/pulseaudio/pulseaudio/blob/master/src/pulse/client.conf.in. Make sure that it has proper permission, owner and group.

Replace @PA_BINARY@ with path to PulseAudio Daemon, possible path is /usr/bin/pulseaudio and set autospawn = no (simply paste it above ; autospawn = yes) . Then reboot the machine.

If the problem still exists, please send us output of command pacmd list.

Thanks,
mkub

Hi,

It seems like problem with loading PulseAudio modules on your host. Can you log sinks? You can do this by using command pactl list sinks. Also, NoMachine’s logs would be useful. Instructions how to gather them is in this article:

https://www.nomachine.com/DT04M00076

Please send output of command and logs to forum[at]nomachine[dot]com.

In a meantime you can try to restore sinks by executing commands below:
pulseaudio -k
/usr/NX/bin/nxserver --restart

If you have successfully restored the devices, make sure that the NoMachine Output is the default sink.

Thanks,
mkub

Hi,

To resolve your problem close active sessions and call:

kextunload /System/Library/Extensions//nxaudio.kext
/etc/NX/nxserver --restart

To load audio devices again to your system, call:

kextutil /System/Library/Extensions//nxaudio.kext
/etc/NX/nxserver --restart

You need to be superuser to execute commands above.

[mkub]

It seems like there is a problem with loading KEXT, by system utilities. To resolve this case, call:

kextutil /System/Library/Extensions//nxaudio.kext

After it is done, in order to approve the KEXT, access the System Preferences -> Security & Privacy -> General panel on your Mac and click on the ‘Allow’ button (see attachment).

(To get more information, follow this article https://www.nomachine.com/AR01P00962)

Then you need to restart nxserver with command:

/etc/NX/nxserver --restart

Did you upgrade your operating system? If yes, which was your previous version? Logs would be useful. Please follow the guidelines here: https://www.nomachine.com/AR10K00697.

Please send them to forum[at]nomachine[dot]com making sure to reference the title of your topic in the subject.

Thanks,

Hi istation,

Make sure, that you chose proper nxnode. Follow the paragraph: How to configure the Mac manually

https://www.nomachine.com/AR10P01001

Is it possible to turn on the microphone in the Microphone Section or maybe the field is grayed?

You can check if the kernel module is loaded with command:

$ kextstat | grep nxau

the output should be similar:

116 0 0xffffff7f80fcd000 0x5000 0x5000 com.nomachine.driver.nxau (4.1.b2) 78172556-B6A4-3112-BA41-E79D18108476

Hi,

We have reproduced the problem which you have described. You can find related TR under the link below.

Audio stutters during NoMachine session
https://www.nomachine.com/TR05Q09270

[mkub]

It could be a hardware related case. To keep the best audio quality without stuttering you could try to decrease the quality of video stream in Display tab. Can you describe stutters? How often they appear and for how long it takes to restore proper stream?

[mkub]

Hi,

Stuttering can be caused either by low speed or high processor usage on the remote host (the Mac in your case).

Do you have other programs open on the Mac whilst you have the session open? If you do, does closing them all other activity reduce the stuttering? Can you try with VP8 encoding?

Thanks,
mkub

Hi,

Which operating system do you use as a server? Make sure that you have a proper inputs/outputs configuration for both client and server. On a client your input/output should be related to the hardware. If it was working before, probably some settings were changed. Not necessarily NoMachine’s. Did you change any of them related to sound before you noticed the problem with audio streaming?

How does it with other browsers? Does it behave in the same way?

Did you try to follow this instruction?

(…) try to uncheck nxnode app – reboot machine – check nxnode again. If this also did not help, you can add whole NoMachine application to Accessibility.

Thanks,

Hi,

Does this situation also happen for audio sources different from Mac Safari? Are you able to hear any sounds through session? What is your operating system?

If Mojave – to resolve the problem, follow links below:

Please make sure that you set everything correctly, this article will be helpful:

Hi Echoo0o,

We are not able to reproduce your problem. Please check your audio settings. On the server default recording device should be set to NoMachine Microphone Adapter and default playback device should be set to speakers / headphones, it has to be different from NoMachine Microphone Adapter. On your client side, playback and recording default devices should be set to your USB headset. You can also verify which device is being in use during VoIP session.

You may also try to check if microphone in session works properly on this website:
https://www.onlinemictest.com/

If you have proper settings and despite this you are still unable to record audio stream with microphone and you hear echo – try reinstalling NoMachine.

Thanks,
mkub

[mkub]

Hi ,

Do you hear echo sound after enabling the microphone, before or after starting VoIP session? It is possible that the microphone is redirected to the sound output. Please check your system’s audio settings and make sure that NoMachine’s Microphone is not an audio output. What is your default output and input?

If settings are fine: Can you record audio input using NoMachine Microphone and compare it with audio output? Are the streams the same?

What is your operating system?

Thanks
mkub
