There's an easier way to acquire this information: $ cat /proc/asound/default/pcm0*/sub0/status If it reads "closed", then nobody is using the card, otherwise, there would be an entry for owner_pid, thus preventing the card to change clock modes outside the multiples of 32/44.1/48 (*1, *2 or *4 depending on SS/DS/QS).
