The speakers started working. Possible reasons:

• updated the MacBook to macOS Sonoma 14.4.1 (23E224)
• Removed wireplumber from the Ubuntu box

The microphone picks up the speakers so it’s basically feedback and not usable.

Could someone tell me where to get 8.10? I’m getting no sound with a Mac client and an Ubuntu server with 8.11 free version. The speaker bit used to work earlier.

I switched to pulseaudio in node.cfg hoping for better results, but no joy. Restarted nxserver, then also  rebooted.

Now I have a proliferation of NoMachine Output – 4 at last count – Output Device-s but none activates the speakers. Similarly there are a bunch of remapped nx_voice_out Input Device-s but none of them connect to the microphone.

pactl list sources|sinks shows everything to be in SUSPENDED state.

At this point I’ll settle for the speakers working.

Sorry for the late response.

> Which sound server do you use on your ubuntu? 

From pactl info: Server Name: PulseAudio (on PipeWire 0.3.48)

> Did you uninstall the old package and then install the new one?

Earlier I had simply upgraded the server. Now I’ve uninstalled the old version and installed the new one from scratch.

Yes, I did that.

/usr/NX/etc/node.cfg has AudioInterface pipewire

It works with .run driver package with version 535.129.03 which I downloaded from NVIDIA site. The 535 version that’s offered by Ubuntu is different and doesn’t fix the problem.

[electrosaur]

Problem remains with 535. Emailed log files.

Server is running Xorg. It has happened again now. I am collecting the server side logs and will submit them.

Yes, that’s correct: I can connect the first time and everything is fine. I should have said that it only happens sometimes on reconnecting. Most times I can reconnect just fine.

About the third option in the link. I am restarting gdm via sudo systemctl restart gdm, but I want to avoid that as it loses the desktop state. Don’t want to use Xvfb because it doesn’t support resizing the display.

Is there something I can look for in the logs to see why things get into the black screen state?

lsmod says nxusb is loaded. I built it again following the instructions just in case. lsusb sometimes reports an NX USB bus but not always. Even when the NX USB bus shows up the camera doesn’t seem to get remoted, though I’m not sure what /dev/ entry it would show up as.

Don’t think this is related to the application, because the focus gets locked on different applications at different times: IntelliJ Idea, Firefox, gterm, …. When the focus is locked, if I try to move or resize any window it will move or resize only the window to which the focus is locked.

It happens at random – I don’ think its some key combination I’m pressing. But I will watch carefully to see if that is the case.

I’ve tried pressing modifier keys, and combination of modifier keys but it doesn’t unlock the focus.

There was a similar issue with an earlier version of NoMachine (see https://www.nomachine.com/TR12K04101). There the advice was to try running ‘xdotool key XF86Ungrab’. I tried that, and it seems to work sometimes but not always.

It does seem to be related to the bandwidth of my connection. If I am hardwired to my router it almost never happens. If I am connecting over WiFi it happens all the time.

Disconnecting and reconnecting *always* fixes it (for a while).

The TR doesn’t quite capture my problem(s). Please see my other post re. recreating NoMachine sources and sinks as well – its not just that things get suspended, its that they disappear altogether. Its simple enough to avoid the suspend-on-idle: one can simply unload the module immediately after remoting in via pactl module-unload module-suspend-on-idle.

Also the recipe I describe, of creating an “alias” for the microphone via module-remap-source doesn’t seem to work all the time. I’m unable to figure out what make it work or not work.

[electrosaur]

Now I’m the state where the NoMachine sources and sinks have all completely disappeared, even though audio features are turned on.

Attaching output of pactl list sinks and pactl list sources.

pacmd list-sources and pacmd list-sinks show “Monitor of Dummy Output” and “Dummy Output”.

In verifying the fix for this issue, can you test that https://test.webrtc.org/ is able to find the microphone?

Now I am completely unable to get the microphone working. Earlier I was able to do that by remapping the source nx_voice_out.monitor via:

pactl load-module module-remap-source master=nx_voice_out.monitor source_name=Microphone

pactl set-default-source Microphone

As to the sources disappearing. I don’t have a recipe for reproducing it. I am not killing pulseaudio, which does make them disappear. I’m not doing anything other than remapping as above. I will post the outputs you ask for immediately that the disappearance happens next.
