Video delay vs sound

Hi,
overall PicpPix is very nice and we enjoy it every night.
Only one problem: using a bluetooth speaker sound and video is never in phase.
Sound comes about .5-1s befor the picure.
Anyway if I use airplay or internal apps. HDMI has it’s own speaker, no problem there.
Any hints?
