linapple problem with Recalbox PI400 v8.1.1

[baco]

Hi recalbox boys !

Can't run any game with linapple on my Recalbox PI400 version 8.1.1...
It seems to start but get a fullscreen with "@##@" and stop, recalbox need to hard reset after that crash...

In linux console if I launch the linapple I've got the following error around 'ALSA':

/usr/bin:./linapple.PI4 &

/usr/bin:ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
