How to prevent nxnode.bin from capturing audio from mpv?

[SoftwareSamurai]

Hi!

I’ve got an Ubuntu 24.04 server PC that I’ve configured mpv to stream audio over my home network. (I have a few Raspberry Pis that capture the audio stream and play synchronized “house music” in those rooms.)

I installed NoMachine so I can remote into the server and do maintenance, etc. That part is working. However I’ve noticed that every time I connect to it from my client machine, the nxnode.bin starts blasting the music from mpv through the NoMachine connection. (I think it’s picking up the output of the mpv process itself by default.) For now I’ve been going into the audio settings an muting nxnode.bin, but I’d like a more refined solution.

Is it possible to configure nxnode.bin to ignore audio from mpv? (Or specific applications?)

TIA!

You should disable sound on the server. Set EnableAudio 0 in the node.cfg file. Does that help?

Well that’s one solution. I was hoping to come up with a better solution that prevents nxnode.bin from connecting to the mpv player. Thanks anyway.

NoMachine streams sound that you have playing on the default output sink. So you can either disable that in NoMachine in the node.cfg or disable it from the connection (https://kb.nomachine.com/DT08U00290#6). Or maybe you could stream MPV to another sink?
