Ringtone through bluetooth headset ?

Hi all !

I have a w890 which I use with a HBH-DS200 (or DS220, not sure) to listen to music.
It works great, but for ringtones : they are played via the phone speaker, so I always miss calls / messages while I am listening to music.

Isn't there a way to have the ringtones play through the bluetooth headset ?

I have patched my audio once (long time ago, so I don't remember precisely what I did). Is this the problem, or is it the same with stock audio drivers ?

Thanks a lot !
