Sound lost in P3DV2

Hi

dont understand why, just after installing a new addon i've lost the sound in the cockpit.

uninstall this addon but the problem persist. No pb outside, sound is ok.

if someone can help me ... that's very frustrating

parameters in my p3d.cfg are :

[sOUND]
PrimaryPlaybackDevice={2FBEA6C0-626B-4A4E-AFFD-36A7EF3956C4}
VoicePlaybackDevice={DEF00002-9C6D-47ED-AAF1-4DDA8F2B5C03}
VoiceCaptureDevice={DEF00003-9C6D-47ED-AAF1-4DDA8F2B5C03}
SOUND=1
SOUND_QUALITY=2
SOUND_LOD=0
UISound=1
