Librem 14 ear bud headset output not working

Seems my headphone / earbud jack is not working. Tried two different sets of Buds, one with microphone one without microphone. No sound at / from the jack. Sound from built in speakers works fine. Any suggestions???


You may need to update your coreboot version to 4.14 to flash the latest version. It should fix headphone jack detection.

Thanks! I will look into that.
This will require changes to my Librem Key correct?

yes, it will require changes to your Librem Key. I went through the process and it should detect you have a Librem 14 with PureBoot. To flash the Heads version requires copying the created file to a USB drive and restarting the computer. Interrupt the boot and enter the Heads menu. From there you can follow the steps to install the new version and generate new keys.

Edit: I don’t think they solved/implemented all the functionality to get the jack working seamlessly. I think you need to manually (some how) switch audio to the jack. I haven’t tried yet.

Thanks MUCH!

if you’re using Pureboot (vs the standard coreboot firmware), you’ll need to wait a little bit for the next Pureboot release.


Thanks for the solution. Flashing the firmware fixed my earbuds on the L-14.

System is as delivered. I messed up on the first boot & setup of my Librem 14. Ended up having to do a factory reset etc. Is there a set of instructions for flashing under PureOS / PureBoot then updating the Librem Key? Seems there are links to different steps for each process but not a step by step to flash & update the Key. I also need to fix issue in (Software) program Error: Sorry, something went wrong: Error StartServiceByName for org.freedesktop.fwupd: Failedto activate service ‘org.freedesktop.fwupd’: timed out (service_start_timeout=25000ms)

Also have unmet dependency issue:

Did not fix dependency problem. Suggestions to fix dependency issues & flash, update, upgrade & update Librem Key???
Thanks All!

@FredWalker nothing needs to be done to “update” the librem key. If you’re running Pureboot firmware, you’ll need to wait until the next update is released for the headphones fix. Instructions are at

For your OS update issue, post a new thread and/or ask in the PureOS Matrix support room.

Do sudo apt full-upgrade

Hello @MrChromebox,

I wanted to let you know that there is a new lucky owner of Librem 14 also waiting for firmware update to make headset and microphone working.

Thanks so much for your hard work!

Have you got an ETA for Coreboot/Pureboot update to fix the audio jack?

the audio jack being selectable as an output was fixed in coreboot version 4.14-Purism-1, released on 6/18/2021, and in Pureboot Release-18, which I just pushed now (though the release notes list the date as 7/6/2021 - testing wasn’t completed before I went on vacation last week)

@MrChromebox - I confirm the audio jack is now manually selectable and the audio plays nicely in my in-ear piece!

I also confirm that the internal microphone is working and quality is significantly better . This means I can now participate in the lengthy conference calls with the other participants hear me clearly.

This is a massive improvement wit the current update. I complement you for all the hard work you put it! Lots of love! :kissing_heart:

Notice to @Kyle_Rankin @todd-weaver @nicole.faerber


How is that a good thing? :wink:

Any news on whether the audio in (headset mic) is now working in latest firmware or when it may start to work?

Would prefer to use (much better) headset microphone via audio jack vs. built-in microphone.

I believe so, you just need to go into settings and select the sound output.

Mine still not working )-:
Just did another update.
still not working after OS update, Under Sounds.
Checking Settings, = “Speakers-Built-in Audio” but that is the only choice???
No choice for output jack. I would think just plugging in a set of ear buds would connect output to the jack???

you need to update your firmware (coreboot/Pureboot). Auto switching based on jack detection is not working yet
