http://www.w3.org/ns/prov#value | - Try sudo lsof /dev/snd/* (yes, you need root, because e.g. pulseaudio will have permissions you don't, so you can not access its /proc/pid/fd) If you see more than one process on /dev/snd/pcmC0D0p, you have more than one thing playing on device 0 of card 0, paused or otherwise.
