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? -- Alexander E. Patrakov
