Hello everyone,

Today, to solve a problem with Thunderbird, I tinkered with timeshift, restored a snapshot from several months ago, then another one, and then once again a snapshot from 24 hours ago.

The result is that I repaired Thunderbird, in a different way, but in the process, the famous issue of the virtual output has appeared. Last night everything was working perfectly.

In pulseaudio, for the output device, I have "virtual output". In configuration, I have nothing.

The command:

inxi -Fxxz

... gives:

Small clarification: the sound from my PC is playing correctly through the bluetooth speakers.

Thank you

    Hello,

    Start by doing the basic checks:

    • Make sure the speakers are on and at a reasonable volume. Check if they work with another device or operating system.
    • Check the sound volume in the system mixer and in the affected application.
    • Replace the speakers with another output (for example, headphones) and test.

    Try installing pavucontrol and from there, change the audio output.

    sudo apt update sudo apt install pavucontrol pavucontrol &

    You should also specify which distribution you are using and with which graphical environment. For example, if you are on KDE, is a phonon backend installed?

    Do you have sound with this command?

    aplay /usr/share/sounds/alsa/Front_Center.wav

    Additionally, on recent distributions, pulseaudio is being replaced by pipewire.

    Regardless of whether you are using pipewire or not, in both cases you can use the pactl command to see what is detected:

    pactl list sinks

    Good luck

    Thank you very much for your reply.

    I am using Cinnamon, the sound was working on Bluetooth speakers. I tried to apply some advice found on Linux forums, and suddenly, when starting up the computer, I entered my password, and then an error message said that Cinnamon could not start.

    So, I booted from a USB stick with a Linux Mint ISO and thanks to Timeshift, I restored a snapshot from the morning of December 25th. And there, the fictitious output was replaced by my sound card.

    Well, I don't understand, and above all, it happened to me the same way a few months ago before resolving "on its own," a week later...

    In your opinion, is this a problem that sometimes appears on forums? Or did I, at one point or another, touch something I shouldn't have?

    Happy holidays.

      Hello ptiboy

      • Sorry for the late reply, I was on vacation as you can imagine. I hope you had a great holiday.
      • Regarding what you describe, I tend to lean towards the explanation that you put your hands where they shouldn’t have been. The parameters (of pulseaudio) don’t change "magically" or spontaneously. They are all ultimately recorded in a profile file, stored in a hidden file/folder in your user directory (e.g. ~/.config/pulse).
        • I suspect that you had, at some points (before or after restoration) one of these files that moved. Since I don’t know exactly what you did, it’s hard to say more.
      • With the problem seeming resolved (at least for the moment), if you don’t have any further discussions, could you mark the discussion thread as resolved? We can always reopen it if needed.

      See you soon and all my best wishes ;-)

      Hello, ptiboy,

      You just need to click on the "Resolved" link (in your first message) at the bottom of the first message in this thread. If you don't see it, let me know and I'll take care of it.

      Have a nice day
