A Question about Sound Play on Nexus One

Unity Engine
,
1

I build a GUI button when one click and onetime sound play.
but the sound is not work for the first time,i turn up&down the Nexus One volume button it’s display “Ringer volume”.
I touch the Home button(I work on Unity iphone befor,I don’t know what is it on Android)and trun the game to the backround,then trun it back again.
The Soundplay is work,and click Nexus One volume button it’s display “Media volume”.
How can I do for this problem,I don’t want to tell my player “Trun it off and trun it on again,You will get the sound!!”.

I am Sorry about my English,but I have no any more ideal to solve this problem.
Thanks any body.

Are you using any plugins? Like the Qualcomm Augmented Reality Unity3 plugin. There is known issue with that one.

erique,you got it, thank you a lot.
In the first scene I just import the QCAR plugin,but did not use it,so not notice it.
I get your remind,then go to Qualcomm forum ane found out it.
