[CM] [snd] save-sound-as

[Anders Vinjar]

Im getting some weird behaviour using 'save-sound-as in a script.
Basically its the same as the example 'extract-channel in
snd.html:

(define (extract-channel filename snd chn)
  (save-sound-as filename snd :channel chn))

(extract-channel "tmp1.snd" 0 0)

This works fine if i call it from snd's listener.

However, running snd as an emacs subjob makes snd pop up a blank
window, and snd hangs foreverafter

(extract-channel "tmp4.snd" 0 0)
