Hello @diavolicchio,

/home/user/.config/awesome/rc.lua:688: attempt to index a nil value (field 'volume')

Looking at your config, line 688 is

os.execute(string.format("amixer -q set %s 1%%+", beautiful.volume.channel))

You have to make sure beautiful.volume exists. AFAICT it should be part of the theme with this config.

The issue with the other button is the same problem.

It's the default Arcolinux distro awesome config, anyone can help?

I'm not familiar with Arcolinux. You should report the issue to them, so that they can fix it.

howdy @diavolicchio,

based on your rc.lua file, you are using the blackburn theme which has the volume widget commented out:
https://github.com/arcolinux/arcolinux-awesome/blob/master/etc/skel/.config/awesome/themes/blackburn/theme.lua#L172

it looks like the arcolinux default is the multicolor theme which does not have that widget commented out.
