Clock does not speak in 13.1.0

[greenfeld]

Clock-10 does not speak or tell the time in 13.1.0 os7 when that option is enabled in the top menu bar.

Similar old issue: #3453

1. the espeak plugin for gstreamer is not available for 0.11 gstreamer version. We have already installed espeak and espeak plugin for gstreamer, but the version installed is for gstreamer 1.0. So we get an exception when we try to get the pipeline: no element "espeak"

   Installed Packages
   espeak.armv7hl -> 1.46.02-6.fc18
   gstreamer-plugins-espeak.armv7hl -> 0.4.0-1.fc18                                                     
   

2. So, the codes tries to handle that exception and use the comand "espeak" instead, but that command does not work on XO-4 13.1.0 build 18. Then, it fails and does not speak at all.

I tried compiling espeak (on XO-4 13.1.0 build 18) from its source code:

sudo yum install gcc-c++ make portaudio-devel
wget "http://downloads.sourceforge.net/project/espeak/espeak/espeak-1.46/espeak-1.46.02-source.zip"
unzip espeak-1.46.02-source.zip
cd espeak-1.46.02-source/src
cp portaudio19.h portaudio.h
make

Then I ran espeak and I got the same error:

./espeak "Hello World"
espeak: wave_pulse.cpp:691: size_t wave_write(void*, char*, size_t): Assertion `stream' failed.
Aborted

The only workaround that I see here is to save the espeak output in a temp wav file and then play it. Something like this:

espeak "Hello world" -w /tmp/espeak.wav ; playwave /tmp/espeak.wav

Speak uses that method, but instead of playing it with playwave it uses gstreamer to play a file.

A workaround to the real problem - no needed in Gtk3 and Gst 1.0 versions

[humitos]

@gary: I attached a patch with a workaround for this issue. I think it's useful for this cycle but we won't need it when Clock uses Gtk3 and Gst 1.0

Please prepare a .xo to include in the next image (and ask dsd to include it).

Is sad ship this activity with a regression like this.

Thanks for the patch humitos! Tested on two XO-4s, and an XO-1.75 running 13.1.0 build 18, also tested with the long distant 802 release (Sugar 0.82.1) on an XO-1. Tested both the English and Spanish spoken time translations. Fix landed in the just released Clock-12.

Thanks for the fix. Just a minor review comment: this creates a temporarily file but never deletes it. Fortunately its not a big deal since the file is small and it will be automatically deleted (on XO at least) at shutdown time. "espeak --stdout" might have been a better option though.
