[Linphone-users] mkv sounds kill linphone appimage

[gegetel]

Hello all,

I have tried many appimages from 4.2.0-alpha.55 to 4.2.0-alpha.96 on several 
pcs with several os (Magia 5, Mageia 7, Debian Buster, last Manjaro) and I 
note it is only usable on the most powerful of these pcs. This is what says 
lshw on this one:

and this is what says lshw on one of my older pcs:

On this other pc and many others, linphone dies as soon as an mkv sound have 
to be played (any signaling tone or even when trying ring mkv sound). These 
are the last messages printed in terminal when trying ring:

(yet these mkv files created by Linphone in 
/tmp/.mount_Linphoxxxxxx/usr/share/sounds/linphone/rings can be played with 
Parole or mpv on all these not so old pcs)

Is there anything I can do or developers can do to correct this behaviour ?

Thank you very much in advance.
