[Solved] Can't adjust sound with volume keys or volume wheel

PointBlank776 · 2021-11-18 13:37:12

I'm still getting the hang of linux, and I can't get the volume keys to work.
I have kmix installed, and I do try to map the shortcuts in kmix's settings but even doing so I get no results.
Without kmix installed, relying on Pulseaudio yields the same issue. I do have a kmix widget on my taskbar, as I read on another forum that it might help, which is what solved the issue for someone else having the same issue, but it didn't work for me. No clue what other information I need to provide, so if I need to provide any specific outputs please let me know

1. Changing the volume itself works, it's only about the shortcuts?
2. X11 or wayland?
3. Run "sudo libinput debug-events", do the keys show up when you press them=
4. "kmix" implies KDE/plasma or do you run it on sth. else (bottom line: what's your shortcut daemon)?

1. Yes, I can change volume in settings and using the little widget, it's just the shortcuts that aren't responsive

2. X11

3.

-event27  KEYBOARD_KEY            +0.000s       KEY_VOLUMEDOWN (114) pressed
 event27  KEYBOARD_KEY            +0.032s       KEY_VOLUMEDOWN (114) released
 event27  KEYBOARD_KEY            +0.920s       KEY_VOLUMEUP (115) pressed
 event27  KEYBOARD_KEY            +0.936s       KEY_VOLUMEUP (115) released

4. I do indeed run KDE plasma, so KDE shortcuts daemon I'm guessing lol

ps aux | grep kglobalaccel

Are the keys grabed?

xev -event keyboard # and press the keys 
sleep 5; xdotool key "XF86LogGrabInfo" # make sure to press one of the volume keys when xdotool hits and check your xorg log for the active (and passive) grabs, https://wiki.archlinux.org/title/Xorg#General

everything seems to be picking up fine I think

You kinda only posted the xev output, but the keys are currently NOT grabbed (assigned to a global shortcut)

Ah, my noob-ness has reared its ugly face

I just tried mapping it in kmix but the settings aren't persistant. After exiting settings and going back I can see it didn't stay mapped

edit: God I'm an idiot... Fixed by removing kmix and just setting global shortcut using pulseaudio
