After upgrading from Ubuntu Studio 22.04 to 24.04.1, I lost all audio functionality. What steps can I take to diagnose and resolve this issue?

I recently upgraded from Ubuntu Studio 22.04 to 24.04.1, and now I’m stuck in this frustrating silence—no audio at all! It’s like my speakers have gone into hibernation or something. I’ve tried a few things, but so far, no luck in getting any sound back. I thought I’d reach out to see if anyone else has dealt with this issue or has any good troubleshooting tips.

So here’s what I’ve done: first off, I checked the basic stuff. I made sure the volume wasn’t muted and that it was turned up. I’ve restarted the system a couple of times, figured maybe that would shake things loose. But nope, still silent. I even plugged in headphones to see if it was just the speakers, but that didn’t work either.

Then I dove into the settings to check the Sound settings to see if it was detecting any output devices. It seems to recognize my audio hardware, but it’s all kind of silent—even the test sounds are just not happening. I’m not super technical, but I fiddled with the output options a bit. I noticed I could choose between different profiles for my sound card, but none of them seem to help. Is there something I should be looking for in there?

I also read online that sometimes upgrading can mess with PulseAudio or JACK, which I guess is part of the sound system in Ubuntu? I’m a bit confused about that. Should I be reinstalling PulseAudio or resetting something? I tried running a terminal command like `pulseaudio –kill` and `pulseaudio –start`, but that didn’t bring the audio back either.

Has anyone else experienced this after upgrading? What steps did you take to get your audio working again? Are there particular commands or settings I might have missed? I’d appreciate any advice because this silence is driving me nuts!

    1. Audio Issues After Upgrade to Ubuntu Studio 24.04.1

      It sounds like you’re caught in a frustrating situation with no audio after upgrading. Here are some steps you can try, even if you’re a bit of a rookie with this stuff!

      1. Check Sound Settings Again

      Go back to your Sound settings and make sure the correct output device is selected. Sometimes it defaults to a different device after an upgrade. Also, make sure that your output volume is up and not muted.

      2. Check ALSA

      Open a terminal and run:

      alsamixer

      This will bring up a mixer interface. Use the arrow keys to make sure no channels are muted (look for “MM” at the bottom) and that they’re turned up.

      3. Restart PulseAudio

      You mentioned trying to restart PulseAudio, but let’s make sure you do it right. In the terminal, run:

      pulseaudio -k && pulseaudio --start

      This first kills the PulseAudio process and then starts it again.

      4. Reinstall PulseAudio

      If that doesn’t work, you could try reinstalling PulseAudio. Run these commands:


      sudo apt remove pulseaudio
      sudo apt install pulseaudio

      After reinstalling, restart your system and check if that helps.

      5. Check and Reset JACK

      If you’re using JACK, it might be worth checking that. Sometimes it’s easier to just reset it. Make sure JACK isn’t running, and try this in the terminal:

      qjackctl

      From there, you can reset your settings or try to reconnect everything.

      6. Look for Updates

      Sometimes, issues like this get patched quickly! Run a full system update:

      sudo apt update && sudo apt upgrade

      Check if there are any updates related to sound drivers or PulseAudio.

      Final Thoughts

      If all else fails, you might want to check the Ubuntu forums or ask for help with your specific hardware details. There’s always someone who’s run into the same issues!

      Good luck and I hope you get your sound back soon!

    2. Experiencing audio issues after an upgrade to Ubuntu Studio 24.04.1 is not uncommon, and there are several steps you can take to troubleshoot the problem. Since you’ve already checked the basic volume settings and tried using headphones, I recommend looking deeper into the PulseAudio settings, as this is commonly affected during upgrades. First, ensure that your output device is set correctly in the Sound settings. To access this, go to Settings > Sound and ensure the correct hardware is selected under Output Devices. You can also try selecting different profiles for your audio device to see if any of them yield sound output. If the output is still silent, check if the correct audio device is selected in the PulseAudio Volume Control (pavucontrol), which gives you more options to manage audio streams and devices directly.

      If you’re still facing issues, you may want to completely reset your PulseAudio configuration. Open a terminal and execute the commands rm -r ~/.config/pulse/* followed by pulseaudio --start. This will clear old configurations that might be causing conflicts. Additionally, ensure that all necessary packages are installed using sudo apt install --reinstall pulseaudio pulseaudio-utils. Following the reinstallation, reboot your system to see if sound functionality has returned. If you still have trouble, consider disabling JACK (if installed) as it can sometimes interfere with PulseAudio. Use systemctl --user stop jack to stop the JACK service and test your audio again. Lastly, please ensure your system is fully updated with sudo apt update && sudo apt upgrade, as there may be essential fixes released since your upgrade.
