Cannot control sound from my jack headphones.

Why I cannot control sound and stop/play from my jack 3.5 Apple earpods and whether it is possible? I didn't find any information about that on google. Sounds work well, but the controls don't work at all.

I am not good at all in Linux sound configuration, so write any commands whose output you need.

bestietamer,

Welcome to the Arch Linux forums. We are glad to help, but, as an author, consider your reader.

What are you using as a desktop environment? Gnome? Plasma? Hyprland? Sway? dwm?
We can see you are using pulseaudio; that is a "good thing"™.
What are you trying to control? mpd? Plex? Spotify? Vlc?
Are you using an X session? Or is it a Wayland session?

My guess is that you are going to find that the earbuds have an input device that is mapped as a 'keyboard'.You will probably end up binding 'keystrokes' from the virtual keyboard device to a program such as playerctl

What I am dancing about is that we can help, but you need to tell us a great deal more about how you configured things.

ewaller, thanks for the answer, I will try to improve.
I`m using Gnome on Wayland.
You said that I use pulseaudio, but pacman -S pipewire wireplumber said that it`s installed, but maybe I don`t understand something?
I`m trying to control general system sound, like I`m clicking on the keyboard sound button.

About earbuds as input device, I examined libinput list-devices output with plugged and unplugged earbuds, it`s the same.
Any ideas?

You are right. I read it correctly, but erred in my response. It is pipewire. Sorry for the confusion.

I am surprised my the libinput information. For example, on my system, which is using a BT speaker right now, libinput list-devices includes

Device:           SONY:SRS-X3 (AVRCP)
Kernel:           /dev/input/event14
Group:            8

Tap-to-click:     n/a

Tap drag lock:    n/a
Left-handed:      n/a
Nat.scrolling:    n/a
Middle emulation: n/a

I see similar sections when I attach my Tozo earbuds. I don't own any iThings, I assumed they used the same model as other BT devices

I don`t use BT earbuds, it`s jack, as I mentioned in my first message.
Unfortunately, looks like libinput didn`t see my earpods

➜  ~ sudo libinput list-devices | grep ^Device
Device:           Power Button
Device:           Video Bus
Device:           Lid Switch
Device:           Sleep Button

Device:           ThinkPad Extra Buttons

libinput debug-events --show-keycodes also debug every button click, except the buttons on my earpods. Is this the end?

Seeing as Apple does their best to avoid standards in order to lock you into their ecosystem, possibly. One sliver of hope I have is whether they just generate ACPI events, though I'm somewhat sure you'd see that in libinput anyway if that was the case. But maybe test for it just in case: https://wiki.archlinux.org/title/Acpid

Nope, there is no events except jack/headphone HEADPHONE plug/unplug which is really weird because microphone in this earbuds works well.

V1del · 2024-11-04 12:50:57

That's probably normal that you just get one plug event (assuming it's a combined headphone+mic jack) and in terms of software reacting to it headphone is usually the more immediate concern (and even if so, on most jack implementations the relevant reroutings of audio/microphone happen on the driver/firmware level, the OS often doesn't receive any information on that).
