Sound (with Alsa) does only work after the second launch of the snap

[Dadu042]

I had this issue with several of my snaps (ie: old games running with core18).

Thanks to the Snapcraft Clinics - 2025-Mar-13 and 2025-Mar-18, Mr Cal found the issue, it is “- pulseaudio” that must be remove from “plugs:” section.
