XPilot 2.00 bêta 49 settings No speaker device detected

Good morning,
I installed version 49 in administrator mode.
When first launched, X-Pilot goes into configuration mode (normal)

I select the microphone and the loudspeaker.
The mic signal bar goes well from blue to red and varies in length, so I always set the level in the setup.

I can hear the sounds of X-Plane 11
And X-pilot replies that the speaker is not configured!

Where is the problem so I can fix it?

Thanks in advance

Problem closed

If I reboot the PC, X-Pilot is waiting for X-Plane
