Sound only as root

[Hans <hans.ullrich@loop.de>]

Hi folks,

I am wondering of an application, which is getting sound only when started as 
root. When I start this aapplication as a normal user, sound is not working.

Please note, that generally sound is working as a normal user, only this 
application needs root.

Environment: 

Debian stable with pipewire, window manager is plasma5 (but every other wm 
shows the same problem).

I am in the group "audio".

What might first help, I would like to know, if the settings of /dev/snd/* are 
correct:

/dev/snd = root:root , drwxr-xr-x

All others below /dev/snd are set 

crw-rw--- = root:audio

Is this correct? If yes, any hints, why this special application will have to 
use root right? 

This application is a flight sim (X-Plane by Laminar Resaerch), a commercial 
product, but if it is a bug in the application, I suppose, they will fix it. 
Theire support is very well. However, I want to get sure, that everything is 
correct by me, before I blame myself.

Any idea might be well.

Thanks for any help.

Best regards

Hans
