dragonplayer-crash-error-log

SUMMARY
The snap version of dragonplayer crashes (each time one tries to play a movie)

STEPS TO REPRODUCE
1. Choose a movie to play.
2. Select 'Open with' and choose dragon plyaer (snap version)

OBSERVED RESULT
The player crashes.

EXPECTED RESULT
Normal operation; play the selected movie.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Lubuntu 20.04 / 20.10 
SW Version: 19.04.2
KDE Frameworks Version: 5.61
Qt Version: 5.12.3

ADDITIONAL INFORMATION
The .deb package works just fine. It is the snap package that is crashing. The deb package is at higher version (version: 20.04.2, frameworks: 5.71, Qt version: 5.14.2) than snap, which is surprising to me, as a snap (or flatpak) is understood to be always latest?!

I've attached error log that I get when I try to launch dragonplayer from terminal. It mainly gives error about not having permission to /usr/share/alsa/alsa.conf. See attachement.

I asked for assistance in snapcraft forum (https://forum.snapcraft.io/t/dragon-player-crashing/18491) and was asked to check snap connections. Following is what I have.

From the comments, the connections seem OK, except that <quote>the snap uses the obsolete pulseaudio interface instaed of the new “audio-playback/audio-record” ones </quote>.
