Headphone adaptor problems

[Guest Vorzico]

Hi there guys..

A couple of days a go i bought a mini usb - 3.5mm headphone jack for the dash from amazon

http://www.amazon.co.uk/Headphone-Duragadg...d_bxgy_ce_img_a

(it says it is compatible with my model..)

However, when i put it in my phone, the sounds all still come out of the speakers.. is there a setting somewhere i need to change???

(I'm running WM 6.1)

Thanks, Vorzico
