Public bug reported:
When a custom audio alarm is set by the evolution calendar function, it
is stored in the calendar.ics file in a VALARM entry as an ATTACH line.
The entry is entered as a file:// url. RFC 2445 defines the contents of
an .ics calendar file and specifies that ATTACH lines must contain URI's
or other particular entries, so this entry is correct. A simple filename
would not conform to the standard.
The evolution-alarm-notify daemon treats this entry as a simple
filename, and since "file:///filepath/filename" is not a filename it
never exists. Since the filename doesn't exist alarm-notify uses the
gnome beep function to create an audio alert rather than the sound.
Suggested resolution, at a minimum, evolution-alarm-notify could check
for the existence of "file://" at the beginning of the entry and, if
present, strip it before the filename check and subsequent passing of it
as an argument to the gnome_sound_play function, which also takes a
filename rather than an URI. This processing is done in
evolution-2.12.0/calendar/gui/alarm-notify/alarm-queue.c function audio-
notification.
To confirm, set a custom audio alarm. Kill the alarm-notify process.
Manually edit the ATTACH line to contain the simple filename. Restart
the alarm-notify process. The custom alarm sound should play at the
appropriate time.
Circumvention
Use the "run a program" alarm option to run a program such as aplay with the
sound filename as an argument. You will have to authorize the aplay program the
first time it runs, but can then check the box to allow it run subsequently
without interruption.
The gui doesn't seem to remember the sound selected the next time the
alarm sound dialog box is opened. One might speculate that
initialization of this dialog box might expect a filename rather than a
gui in the calendar.ics file, but I haven't checked this wild guess.
