Souncard RME multiface click and no multisound


I did a recent installation of Leap with OpenBox, hoping that RME multiface soundcard would be easier to install than on over config.
Happily it was easy to get some sound after the installation, I installed alsa-firmware, hdspconf, hdsploader and hdspmixer, I put an entry to run hdspmixer in ~/.openbox/autostart (with a little test to run it only when the soundcard is plugged, that’s cool on a labtop :slight_smile: ).
But it does’n works as well, sometimes I get annoying click at then end of a youtube clip, and if I wan’t to start another clip I lose the sound definitely until logout…

I hope someone else have this soundcard or someone know what to do !
Thank you
