609 Keyword: Value:

|
610 ------- -----
|
|
|
611 sound A string of raw sound data, or the name of another sound to
|
|
|
612 play. The symbol `t' here means use the default X beep.
|
|
|
613 volume An integer from 0-100, defaulting to `bell-volume'
|
|

614 pitch If using the default X beep, the pitch (Hz) to generate.
|
|
|
615 duration If using the default X beep, the duration (milliseconds).
|

616
|
|

617 For compatibility, elements of `sound-alist' may also be:

620 ( sound-name <volume> <sound> )

|

624

625 Caveats:
|

|
626 - XEmacs must be built with sound support for your system. Not all

627 systems support sound.
|
|
|
628
|
|
|
629 - The pitch, duration, and volume options are available everywhere, but
|
|
|
630 many X servers ignore the `pitch' option.
|
|
|
631
|
|
|
632 The following beep-types are used by emacs itself:
|
|
|
633
|
|
|
634 auto-save-error when an auto-save does not succeed
|
|
|
635 command-error when the emacs command loop catches an error
|
|
|
636 undefined-key when you type a key that is undefined
|
|
|
637 undefined-click when you use an undefined mouse-click combination
|
|
|
638 no-completion during completing-read
|
|
|
639 y-or-n-p when you type something other than 'y' or 'n'
|
|
|
640 yes-or-no-p when you type something other than 'yes' or 'no'
|
|
|
641 default used when nothing else is appropriate.
|
|
|
642
|
|
|
643 Other lisp packages may use other beep types, but these are the ones that
|
|
|
644 the C kernel of Emacs uses.
