Comment 0 for bug 1638721

As reported by mterry in his $SNAP exec patch <https://code.launchpad.net/~mterry/indicator-datetime/snap-root/+merge/308171>:

> The com.ubuntu.touch.AccountsService.Sound.xml file
> has hardcoded paths to a couple sound files.
>
> ALARM_DEFAULT_SOUND and CALENDAR_DEFAULT_SOUND
> are replaced in many files. Some data (gschema)
> and some code. The code instances can easily be
> changed to prefix $SNAP. The data files would
> need a rethink.
