Devo8s Buzzer problem

Hello everybody
I just updated my Devo8s with Deviation 5.0.0 version. Now the buzzer no longer works at all (timer works). Everything else works fine!
After that, I installed the 4in1 module from BG... and it's giant, I can fly all my Walkera helicos (v120d02s, v200d03 and 4f200lm), but also my xk k110, my Hubsan X4 H107 and also my HK Q-bot! This is another great new radio!
Can you help me?
Thank you
