"Dummy Output", no audio after installation of Fedora

Once I install the OS I have no audio and in the settings under audio output devices only “Dummy Output” is shown. HDMI or AUX also didn’t work, only connecting a Bluetooth device works.

I just bought a new Laptop and installed a few Linux distros right after, and I am now landing on Fedora (I’m here to stay). I’ve had this problem with all the distros I have tried (Mint, Arch, Manjaro, PopOs).

I have tried finding the solution on other forums, but nothing seems to be working for me.

Here some device info:

It looks like this problem has been reported here before:

Does the provided workaround not work for you?

Edit: Nevermind, I see that you said that you were able to get it to work with a bluetooth device and that is as far as the other users got as well. You might ping that other thread and ask if there has been any further progress on getting your audio device to work, but it has only been about a month since the last update, so I wouldn’t get my hopes up.

Thank you for the reply. Someone just posted something there that may help. I will look into it, thanks :slight_smile:

You might want to consider looking at hardware information and device drivers.

  • Hardware information

It is always useful to include detailed information on your sound hardware when filing a sound-related problem. To produce this information, run this command:

$ alsa-info.sh --no-upload

It will generate a file containing detailed information about your sound hardware with the name /tmp/alsa-info.txt. Attach this file here (Ctrl + e to insert preformatted text).

  • Check which Kernel driver is in use by PCI devices

To display kernel drivers handling each device, use the lspci (List PCI) command with the option -k.

$ sudo lspci -k

thanks for wanting to help.

I didn’t see any trace of Linux recognizinig any audio device.

I just gave up and tried installing windows to see if it was maby a hardware issue, and I also had a lot problems with that. Windows boot stick didn’t recognize the SSD, I solved that, but then after installing windows didn’t recognize my Touchpad, Audio card, or Wifi card. So I just gave up and returned the Laptop, just wanted to say this for anyone having this issue with the same Laptop.

Thanks again for trying to help. :slight_smile:
