Music Player Won't Play - 'muted'

I've had my N95 for over 7 months and now over the last 2 weeks the music player just won't play any tracks.

The tracks play as ring tones or text tones but not on the music player or through the gallery. I have managed to find out that the player is muted however even after using the volume controls, ensuring that all the volumes are on the loudest - the message shows that the player is muted.

Can anyone tell me how fix this ?? It seems to have happened after I switched from using the handsfree kit to my bluetooth :(

Help .. please !
