Subject: play-sound causes "Invalid sound specification" on valid :data (on Windows)
Date: Fri, 15 Jun 2007 21:07:29 +0200	[thread overview]
Message-ID: <4672E371.9050908@gmx.de> (raw)

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

- Load emacs -Q
- Create a valid .au file in a string (it's easier than .wav):

(setq mysound (concat ".snd"       ; magic number
		      "\0\0\0\30"  ; sound offset 0x18
		      "\0\0\0\1"   ; sound length 1 byte
		      "\0\0\0\2"   ; encoding 8-bit PCM
		      "\0\0\37@"   ; sampling rate 8kHZ
		      "\0\0\0\1"   ; 1 channel (mono)
		      "x"))        ; some random "sound"

- check if the string is really unibyte, as it should:

(multibyte-string-p mysound)
  => nil

- play it

(play-sound `(sound :data ,mysound))
  => (error "Invalid sound specification")

- write it to a file

(with-current-buffer (find-file-noselect "~/mysound-tmp.au")
  (delete-region (point-min) (point-max))
  (insert mysound)
  (save-buffer 0)
  (kill-buffer nil))

- Playing it from there does not produce any error, but not sound either
  (should produce a short click sound; tested with other players).

(play-sound '(sound :file "~/mysound-tmp.au"))

- Other .au (and .wav) files play just fine, but no longer if I put them
  into a string.
