bug with audio

Dear,

I have a wireless headset logitech witch work with an usb key. If I launch a movie and then remove the key, the output doesn't change anymore to my display integrated speakers. It bug in the other way too. If I plug my key after launching a movie, the audio doesn't output in my headset but with my speakers.

That worked great before.

bye.
