    I’m using the free version of NoMachine to connect to my Fedora 32 laptop from my Windows 10 PC.  I have the option selected to mute audio on the server but I still hear sound coming from both my laptop and my desktop whenever I play audio in the Fedora 32 session.

    I’m using NoMachine version 6.11.2 on both the laptop and the desktop.  On the laptop I’m running Gnome 3.36.6 on X.

    Hi,

    We could not reproduce this issue in your evironment. What output device are you using on laptop (built in speakers or something else)? Did you try to uncheck and check again “Mute audio on the server” option?

    Please, can you provide also the output of these commands when the NoMachine session is running:

    1. List files in /dev/snd:

    ls -lrt /dev/snd

    2. Check if PCM mixer control is available for specified sound card:

    for dev_id in $(ls /dev/snd | grep controlC | sed -e 's/controlC//g'); do amixer -c $dev_id get PCM; done

    3. List available sinks

    pacmd list-sinks > list_sinks.log

    and attach “list_sinks.log” in you reply.

    I’ve tried disabling and re-enabling the mute server audio option with no change in behavior.

    The output of the first command:

    The output of the second command:

    Simple mixer control 'PCM',0
    Capabilities: pvolume
    Playback channels: Front Left - Front Right
    Limits: Playback 0 - 255
    Mono:
    Front Left: Playback 0 [0%] [-51.00dB]
    Front Right: Playback 0 [0%] [-51.00dB]
    amixer: Unable to find simple control 'PCM',0

    I’ve attached the output of the third command as requested.
