This is an important point for my search! And no, this system is pure Debian (except that is been upgraded since many many years. I believe, the first installation was 2010 or so). Debian is so stable and reliable, so I did not need change much. Of course packages are uninstalled during that long time and things also changed (like alsa, then pulseaudio and now wireplumber / pipewire for example). And as a carefull user, I purged old configurations (using aptitude purge ~c) So, this is just clean Debian 12 stable. Hope, the vendor of the application will also have some hints. Fine is, I am now sure and it is proven, my system is set correctly. This is an important point for me. Thanks for the feedback.

I'm in the happy camp of not needing all those pluses. My laptop has no seats ;-) Cheers -- t signature.asc Description: PGP signature

Those are super important here. When you login to Debian, there's various black magic that happens with "session" and "seats" and so on. One of the things involved in that magic is adding your account to the ACL on the audio devices.

With some luck and patience you might spot where it's trying to do things and failing. Cheers -- t signature.asc Description: PGP signature

Pipewire has a pulseaudio module. But before I tested with pulseaudio, both showed no difference and no success. Best Hans

Sound only as root
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

Sound only as root ?
Hi all, on my recent woody I only get sound when running as root (either running completely as root or su ing into root from a normal user under x will give me sound output). So I guess this is a standard feature of debian. How to change that ? TIA Michael Meding
