acpid: volume example from Wiki not working

I'm trying to get Fn volume keys working via acpid https://wiki.archlinux.org/index.php/Ac … me_control

[root@arch events]# acpi_listen 
button/mute MUTE 00000080 00000000 K
button/volumedown VOLDN 00000080 00000000 K
button/volumeup VOLUP 00000080 00000000 K
^C
[root@arch events]# cat /etc/acpi/events/vol-d
event=button/volumedown
action=amixer set Master 10- unmute
[root@arch events]# systemctl restart acpid.service 
[root@arch events]# amixer get Master
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 67 [77%] [-15.00dB] [on]

< pressing Volume Down several times >

[root@arch events]# amixer get Master

  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono

[root@arch events]# journalctl -n5

Running amixer set Master 10- unmute from terminal successfully changes volume.

Re: acpid: volume example from Wiki not working

The last few messages are from the script in /etc/acpi/handler.sh, so unrelated to the volume event. Does it work if you run the command from a root shell:

$ su -
# amixer set Master 10- unmute

Yes, it works.

Re: acpid: volume example from Wiki not working

Stop the acpid service, and run it from a terminal:

# systemctl stop acpid
# acpid --debug

Then press the buttons and post the output here.

Re: acpid: volume example from Wiki not working

Judging by the output, it successfully decreased the volume. See if it's the same when launching acpid from systemd:

# systemctl edit --full acpid.service # append --debug to ExecStart line
# systemctl restart acpid.service
# journalctl _SYSTEMD_UNIT=acpid.service # post output

Not a System Administration topic, moving to Kernel and Hardware.

Re: acpid: volume example from Wiki not working

Looks like it's a systemd issue then, or an error elsewhere which is triggered by a condition in systemd or the service file. Opening an issue (mentioning it works when running acpid manually) may give more clues:
