Headphones Recognized But Sound Goes To Laptop Speakers

If I open sound settings in the toolbar or open Pulse, the headphones show connected when plugged in and not connected when not plugged in. In either case, sound goes to the laptop speakers. I am on Cinnamon with all updates current. Below is my inxi -Fxxxz --no-host. Jack works fine in Windows, and has worked with no issues in other distros. I know it isn’t purely an EOS/Cinnamon issue since my headphone jack works as expected on a nearly identically setup computer just with different hardware. Any help would be greatly appreciated.

Moderation Edit Fixed output formatting.

Which one are your headphones connected to?

Sorry, the jack that fails is the Intel one. The USC-C to 3.5mm adapter is my current workaround to at least get something working.

The first thing i would try is to use pavucontrol on configuration tab disable all other devices and enable the headphone only, if this is not working you can try paprefs and enable simultaneous output:


I will give these ideas a shot later today. Thanks!

Tried both with no change. Despite showing headphones when plugged in and speakers when not, the sound still comes from the laptop speakers alone no matter the configuration.

what does alsamixer from terminal shows you?

Which option? Available sound cards are HDA Intel PCM, NDA NVidia and USB-C to 3.5mm Headphone Jack Adapter.

Likely this one:

Changed it in alsamixer with no impact. Even with sound settings reflecting the headphone state, playback goes to laptop speakers when Intel is selected. At least it works right with the usb-c>3.55mm adapter selected. Thanks for trying to help.
