Sound playing time?

soundResult = MasterAudio.PlaySound("music");

is there any way in the result to get the milliseconds played at any point in time during Update(), i.e if you wanted to sync something to a looping audio file, I'd look at the milliseconds currently since the start of the track.

I do try storing the time.timesincelevelload when you start play, but wondered if comparison to the audio file would be more accurate.

thanks
