 Hi Albert,

 > stat(your_audio_device, &sbuf)

 That's the first thing I tried, and /dev/snd/pcmC0D0{p,c} weren't updating
 their atimes when the device was open or used.  Could you confirm whether
 you see the same thing?

 It's not clear that recording the last time the device was opened via
 atime, if it did that, would be good enough -- if someone's been listening
 to music for the last ten minutes, I need to know both that it was last
 opened ten minutes ago, and that it is currently open.
