I have discussed the problem with pulseaudio developers. According to my understanding (that may be wrong), we have a classic ABBA deadlock. The device will go away when its reference count goes to zero. The reference count will go to zero when there are no open fds. The mixer fd will be closed when it gets a -EIO, i.e. after the device goes away. If the above understanding is correct, I think that waiting for zero references should be at least questioned. -- Alexander E.
