You are using a Dell XPS-15-9560. This is what I found when I did a Google AI search for “audio problems with dell XPS-15-9560 and Ubuntu. Make of it what you will.

Audio problems on the Dell XPS 15 9560/9550 with Ubuntu commonly involve

“dummy output” (no audio device detected), no sound from internal speakers, or issues with headphone detection

. These issues often stem from conflicts between the Realtek audio codec and the Linux kernel, or lack of support for specific audio hardware configurations in older Ubuntu versions.

Here are the solutions and workarounds for these audio problems:

1. Update Kernel and System

Using a modern kernel is critical, as recent kernels (6.8+) have better support for the XPS audio hardware.

  • Update Ubuntu: Run sudo apt update && sudo apt upgrade -y to ensure you are on the latest packages.

  • Update Kernel: If using an older version, upgrading the kernel to the latest stable version (e.g., 6.11 or later) can fix audio driver issues.

  • Use OEM Kernel: If using Ubuntu 24.04, consider switching to the OEM kernel to resolve driver compatibility.

2. Fix “Dummy Output” (No Sound Detected)

If your system only shows “Dummy Output” in sound settings, try these fixes:

  • Reload ALSA: Open terminal and run sudo alsa force-reload to restart the sound system.

  • Adjust modprobe.d: Edit the configuration file by running sudo nano /etc/modprobe.d/alsa-base.conf and add options snd-hda-intel dmic_detect=0 to the end of the file, then reboot.

  • Add User to Audio Group: Ensure your user is in the audio group to allow access to the sound card:

    bash

    sudo adduser $USER audio
sudo adduser $USER pulse-access

    Then log out and log back in.

3. Fix Internal Speaker/Woofer Issues (No Bass/Quiet)

Some XPS models have 4 speakers (2 woofers, 2 tweeters) that do not work properly on Linux, causing “tinny” sound.

  • Update to Newer Ubuntu: Upgrading to Ubuntu 24.10 or later may fix this, as it includes the necessary audio driver updates (kernel 6.11+).

  • Check Audio Profile: Open pavucontrol (PulseAudio Volume Control) and ensure the correct profile (e.g., Analog Stereo Duplex) is selected.

4. Headphone Jack Issues

If headphones are not detected or produce a loud noise:

  • Run alsactl: Run sudo alsactl restore in the terminal, which can sometimes detect the headphones.

  • Check BIOS: Ensure “Audio” is enabled in your Dell BIOS/UEFI settings.

5. Alternative Workarounds

  • Disable Secure Boot: In some cases, disabling Secure Boot in the BIOS/UEFI allows necessary, unsigned kernel modules to load, restoring audio.

  • Install alsa-tools: Install the tools with sudo apt install alsa-tools to ensure you have necessary configuration files.

If these do not work, it is worth checking for BIOS updates on the Dell Support website, as these can resolve hardware detection issues with Linux.

Dear Ubuntu Support Community,

Thanks. The issue appears to have been fixed with the latest update to Ubuntu.

Dear Ubuntu Community Hub Support,

No audio, no sound, no internal speakers detected, .

At a loss.

The issue persists. This morning, 5 February 2025, 11:00, UK. After power down and power up over night 4 Feb..

The issue appears intermittent and haphazard and arbitrary.

Updated Ubuntu via Software Updater and rebooted. The issue continues to persist.

Hello,

I’m trying to find the solution I did in my system in order for the solution to be permanent. As it was mentioned the “dummy output” is the reason for not having audio, yet it was a long time ago since I found a solution to that problem and that solution is under old ubuntu forums. I will try to see what I did and post back.

Regards!

Hello,

unfortunately I cannot have access to old ubuntu forums, since this is a work in progress, as I found out. I would advice you to upgrade alsa-ucm-conf, since I did it last night and didn’t face any issue, and since I guess that it is a package related to your issue.

If this option doesn’t work, I would advice you to follow the solutions posted earlier one by one and see if you will get any solution. I vaguely remember that I had to edit a file permanently in order for the “dummy output“ to get removed from my system.

Regards!
