Well, qtplay isn't part of OS X. Do you have the audio bell set in your Terminal preferences? I have no idea why applescript isn't working but you can play sounds with afplay. Type the following for the proper syntax (the man page is sparse).
Of course there are a number of open source options.

A user's default permissions when creating new files or directories is set by the umask of either the system or in the startup script of the user itself. For example, I have 'umask 022' in my .profile which means that my default permissions will be 755. Typically, the system default umask is 022,... (1 Reply)

pcap_get_selectable_fd
PCAP_GET_SELECTABLE_FD(3PCAP)PCAP_GET_SELECTABLE_FD(3PCAP)NAME
pcap_get_selectable_fd - get a file descriptor on which a select() can be done for a live capture
SYNOPSIS
#include <pcap/pcap.h>
int pcap_get_selectable_fd(pcap_t *p);
DESCRIPTION
pcap_get_selectable_fd() returns, on UNIX, a file descriptor number for a file descriptor on which one can do a select(), poll(), or other
such call to wait for it to be possible to read packets without blocking, if such a descriptor exists, or -1, if no such descriptor exists.
Some network devices opened with pcap_create() and pcap_activate(), or with pcap_open_live(), do not support select() or poll() (for exam-
ple, regular network devices on FreeBSD 4.3 and 4.4, and Endace DAG devices), so -1 is returned for those devices.
Note that a descriptor on which a read can be done without blocking may, on some platforms, not have any packets to read if the read time-
out has expired. A call to pcap_dispatch() will return 0 in this case, but will not block.
Note that in:
FreeBSD prior to FreeBSD 4.6;
NetBSD prior to NetBSD 3.0;
OpenBSD prior to OpenBSD 2.4;
Mac OS X prior to Mac OS X 10.7;
select() and poll() do not work correctly on BPF devices; pcap_get_selectable_fd() will return a file descriptor on most of those versions
(the exceptions being FreeBSD 4.3 and 4.4), but a simple select() or poll() will not indicate that the descriptor is readable until a full
buffer's worth of packets is received, even if the read timeout expires before then. To work around this, an application that uses
select() or poll() to wait for packets to arrive must put the pcap_t in non-blocking mode, and must arrange that the select() or poll()
have a timeout less than or equal to the read timeout, and must try to read packets after that timeout expires, regardless of whether
select() or poll() indicated that the file descriptor for the pcap_t is ready to be read or not. (That workaround will not work in FreeBSD
4.3 and later; however, in FreeBSD 4.6 and later, select() and poll() work correctly on BPF devices, so the workaround isn't necessary,
although it does no harm.)
Note also that poll() doesn't work on character special files, including BPF devices, in Mac OS X 10.4 and 10.5, so, while select() can be
used on the descriptor returned by pcap_get_selectable_fd(), poll() cannot be used on it those versions of Mac OS X. Kqueues also don't
work on that descriptor. poll(), but not kqueues, work on that descriptor in Mac OS X releases prior to 10.4; poll() and kqueues work on
that descriptor in Mac OS X 10.6 and later.
pcap_get_selectable_fd() is not available on Windows.
RETURN VALUE
A selectable file descriptor is returned if one exists; otherwise, -1 is returned.
