I have a 32-bit system running jessie that gives the following error the first
time that I try to use ALSA following a reboot:
  ERROR: Cannot open audio device: hw:0,0
  error number -16
  Device or resource busy

It doesn't seem to matter how long I wait following a reboot, the above error
always occurs on the first use. If I run the same program again, even if I do
so immediately, the error goes away and everything is fine.

Is there some way to find out what process is using ALSA when snd_pcm_open()
returns that error? (If indeed there is such a process.)
