very strange, the device is opened but it's stopped, and cat(1) cant do that. can you confirm that the ``cat /dev/arandom >/dev/audio'' command was still running during the whole operation. Are you sure it didn't terminate with a error? play.active=0 indicates that the device is stopped and play.samples=0 means it has played 0 samples, so it's normal you dont hear anything so far. during the ``cat /dev/arandom >/dev/audio'' command the play.active should be 1, and play.sample should be increasing. fwiw, if the ``cat /dev/arandom >/dev/audio'' terminates with ``Device busy'', you can use fstat(1) to see which programm is using it, (and kill it), example: $ fstat /dev/audio USER CMD PID FD MOUNT INUM MODE R/W SZ|DV NAME aucat aucat 31279 3 / 1709 crw-rw-rw- rw audio0 /dev/audio $ sudo kill 31279 -- Alexandre
