I had _not_ suggested he required the user field. Let me try this
again;
m h dom mon dow
0,15,30,45 * * *
0,15,30,45 * * * *
He does not have an entry for the 'day of the week' field . I had never
tried using cron with less thæn the suggested argument fields, so I
tested it. A working example was changed to his, dow missing,
example.
(working example)
15,45 8-22 * * * root /usr/local/bin/play /usr/lib/sounds/ring.au
(Test without 'dow' field)
1-20 8-22 * * root /usr/local/bin/play /usr/lib/sounds/ring.au
The test did not work. As I read crontab(5) it shouldn't work.
"
commands are executed by cron(8) when the minute, hour,
and month of year fields match the current time, and when
at least one of the two day fields (day of month, or day
of week) match the current time (see ``Note'' below).
cron(8) examines cron entries once every minute. The time
and date fields are:
[ snip field parameters]
A field may be an asterisk (*), which always stands for
``first-last''.
"
Adding the dow field to the above test example, did in fact, work.
I guess my original post
># m h dom mon dow user command
>so you might try

Was not clear enough (?).
