XPS13 9343(2015) Bluetooth issues

Hi there,

I have successfully installed Debian Jessie in dual boot on my XPS 13 which came with Win 8.1.

I have a remaining issue which is very annoying. When I switch from Windows to Debian, I have bluetooth working but no sound.

So I follow Barton's advice to cold boot the laptop to get the sound card working. That does the trick perfectly, but when the sound is finallly back, I have no bluetooth anymore. I mean the bluetooth service is up but it can't detect anything and my mouse is unable to connecte anymore.

It seems that it does not work under WIndows too until I cold boot to get the sound.

Do you have any thoughts on this ?
