[Sugar-devel] [PATCH Sugar] Close audio device after text to speech - OLPC #11829

[godiard at sugarlabs.org]

From: Gonzalo Odiard <godiard at gmail.com>

In xo with alsa, if we keep opened the audio device after
doing tts, other activities can't use it.
We need close the device after the eof message is received,
because the message came a little before the sound has finished.
