As addition infos, I don't use pulseaudio. Spotify has no use flags enabled : Installed versions: 1.0.88-r1^ms(01:24:16 PM 08/27/2018)(-libnotify -pax_kernel -pulseaudio -systray)
It used to work perfectly fine with the previous version, so I assume something is broken in this new one.
I'm attaching the strace from advanced troobleshooting, I've had to zip it to make this forum accept it, sorry for the inconveniance.
Solved! Go to Solution.
