hi, is anyone facing stock music player in stock rom DXLP9 ICS, when player the music it will auto stop?

i try to reflash to same stock rom again but the result is still the same.
anyone facing this problem after upgrade official stock rom ICS???

it seems like the music stop when the phone is in deep sleep but i never rooted nor flash any other rom or kernel, it just all stock.

what i noticed is eventhough the screen is not off, the music will stop but the play button is still there, it just the music is not playing anymore. after i touch to select any function or apps, then the music will continue back but it won't last for 3 seconds...
