Audio issues in FW21?

[Christian Schaller]

Hi,
I was trying to connect a headset to my laptop today (running the current beta) and I noticed that I got no sound out. Looking inside the control panel I notice that when I plug in my headset into the headphone jack, the internal speaker output disappears, but no headphone output appears.

First of all I didn't it use to be possible to switch to internal speakers even when headset is connected? Also are more people than me seeing the issue of  headset output not appearing? I am on a Lenovo T430s.
