I can suggest two very rough tests. However, as restarting PulseAudio 
helps, I doubt that they will find anything, because you need to test 
that at the time PulseAudio starts.

1. Start pavucontrol. Make sure that your app plays a sound. Look into 
the pavucontrol window and see if you can see the stream on the first 
tab. If you can, then the app is definitely using PulseAudio.

2. Start a terminal. Make sure that your app plays a sound. While it is 
playing, run this command in the terminal:

fuser -v /dev/snd/pcm*

If it prints anything that is not about pulseaudio, then that app uses 
ALSA directly in a way incompatible with PulseAudio.

Tanu: would a linux-specific patch be welcome that attempts to log which 
process keeps the device open? If so - should I walk /proc myself, or 
defer to fuser?
