qtopia, earphone and mediaplayer

Hello everyone.

Trying qtopia 4.3.3, I noticed that if I
plug in the headphones while
listening to a song, the sound is played
through the FR's loudspeaker
at the same time as coming through the
headphones.  If I disconnect
the headphones, the loudspeaker
deactivates.

Doing a hexdump of /etc/input/events0, I see the
following:

(Connecting the headphones)

root at om-gta02:~# hexdump -C /dev/input/event0

00000000  99 67 cc 48 62 69 0a 00  05 00 02

As you can see, at position 0x0c the value changes from 1 (if
connected) to 0 (if disconnected) - so that seems good.  Therefore I
think this problem must be something in the media player application.

Any ideas about this?
