Usb Headset don't appear in sound menu, but listed in lsusb

Hello everyone, i recently installed kali linux, but my usb headset don't work (A Plantronics rig 7.1)
I've got the hdmi audio in the sound settings :
Attachment 2527

lsusb say my usb soundcard integrated to the headset is detected :
Attachment 2528

and cat /proc/asound/cards say the same :
Attachment 2529

and here is cat /proc/asound/modules :
Attachment 2530

I'm running the latest 64 bits Kali Linux version (2017.1)
I've installed alsa and all the additional stuff (alsa-utils, alsamixer etc...)
But alsa-base.conf is missing

I tried everything i can found on google, but no one worked
Thanks in advance
