Well, I assume that if it's not playing the pcm trigger will neither be called during suspend nor during resume, since the actual device suspend is later, this is only the pcm suspend. Actually, could the device suspend sleep and wait? Then we could play a sound during suspend if we somehow manage to make the audio device suspend last, and the pcm first :) johannes
