hey kuba,

to begin with, the root cause identification dated back to a few years,

From my research online, below set of instructions, help us resolve both audio and mic issues from a given dumb terminal to the virtual desktop interface (vdi) from NoMachine client-server interconnection both at home and in office premise.

1 enable mic post login to a nomachine session

2 execute below scripts

rm -r ~/.config/pulse*

pulseaudio -k

sudo /etc/NX/nxserver –restart

3 enable mic post login to a new nomachine session

Please find attached zip archive file 20240609.vdi.zip.

remote Linux distribution is Ubuntu (Ubuntu 22.04.4 LTS jammy). Desktop environment is gnome…

Thank you britgirl.

Hello kuba,

Through a physical session, there is no issue on client end (nxplayer).

The server (nxserver) is a remote machine. To it, I do not have physical access to test physical session.

Please find attached nxplayer and nxserver configuration [nx_player_server_result.txt]. In remote session with device nx_audio_in, (recorded) voice can be heard with a static <server_audio_remote_session.flac> unlike a physical session audio from nxplayer machine <client_audio_physical_session.wav>.

1) In this use case of nxplayer (8.9.1) machine being a laptop and nxserver (8.9.1) being virtual desktop interface (VDI), voice includes a static. (attached files to this message…)

2) In another similar use case of nxplayer (6.17.1) machine being a dumb terminal machine and nxserver (8.9.1) being VDI, recorded voice includes broken audio… <I requested help desk to help update nxplayer  from 6.17.1 through 8.9.1>

I emailed logs as a response to this topic post email to email distribution list forum..nomachine.com.

Please review and analyse.

We have few use case scenarios as below.

<1> is within office dumb terminal to VDI machine connection (voice breaks in between)

<2> is with home system to VDI machine connection (voice does not break – voice is having some static)

<3> is with home system [Garuda Linux] to home systems [Garuda Linux and Ubuntu Linux] (voice does not break -voice is having some static)

My office VDI system, from inxi command, does not show any audio device. it only shows three audio servers in running state.

one of the home (server) sysmytems, from inxi command have below output
