Astro A50 Microphone issue

Hello,
To make a short story, i've bought the first A50 when they where released on the asto website, and this morning when i pluged the headset to charge it, the microphone has just stoped working.
I had no feedback anymore in the headset, no sounds comes in windows "recording device".
I tried to restart computer, mute unmute on the headset, pairing with the mixamp, changing USB port. Nothing changed.

Thanks
