Hi all,

I'm developing an audio driver and having an issue with the sleep mode under windows 7.
I was playing audio before entering the sleep mode.
After wakeup form sleep the following states are entered:
1 (aquire)
2 (pause)
3 (run)

Then sound is played, but sometimes it stops after ~1,4 seconds and the stop state is entered again:
2 (pause)
1 (aquire)
0 (stop)

Does anyone know why this happens? I'm assuming that the driver should remain in the run state until the user stops the sound.
