[Solved] User should in audio group to access audio devices in Skype.

Hi,
My system is x86_64, KDE, no pulseaudio, Creative X-Fi Music.
2 day ago i found out that i can't make calls because i have "Problem with audio playback". Adding user in audio group solved the problem.
WTF? Wiki clearly says no to add user in any groups.
Reinstalling Arch didn't solved the problem, only adding user in audio group did.
-------------------------------------------------------------------------------------------------------
I got smth strange. It is needed to install alsa-utils, alsa-plugins, lib32-alsa-plugins, lib32-pulse, then uninstall all of them and also libpulse, alsa-lib, lib32-alsa-lib, then install libpulse, alsa-lib, lib32-alsa-lib .. . and the sound is here.
i removed user from audio group

You have to be in audio video etc to make changes and use that applies to all linux distros arch does not hold your hand its all in the wiki. https://wiki.archlinux.org/index.php/Us … tem_groups

Wrong, logind provides this access. Adding users to audio/video/storage/whatever is no longer needed.

@OP
Post the output of

$ loginctl show-session $XDG_SESSION_ID

@mandog
Not really, I'm using GDM/Gnome and my current user can do pretty much everything (mounting external disks, poweroff/reboot/syspend, etc.) despite being only in the users group and the user's own group.
I don't really know the technical details of the policy, but apparently nowadays the policy is not simply based on groups. So can somebody explain to me the policy settings that are at work? Polkit and systemd-logind maybe?

edit: @msthev thx for the info

Logind only provides this access within a given tty session. This will vary depending on how you start X. If you use a display manager, I believe they take care of the new logind session. If you use xinit/startx and you start X on *the same* tty as you launch it from, then you'll be under the same login session and these permissions will be provided.

If you use xinit/startx on tty1 but run X on tty7 (with the vt# option to X) then you will not get these permissions from logind, but will need to add your user to the relevant group(s).
