milestone music stops audio but appears to be playing still????

[Guest iamdarren]

With my milestone I have a problem when playing music it will cease to have sound after about 5 mins of play. I get this everyday and find the only way to sort it is to reboot phone. I don't think its so much a software eror I think its the hardware. Its really annoying when walking, today I have got the bluetooth headset and its been ok.

I would like to know if anyone had has anything similar, if so I could use the insurance to get it replaced.
