Subject: Move creating AudioStream instance when playing tts is requested
X-Git-Tag: accepted/tizen/8.0/unified/20241011.164854~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=180b3971a0311a981c0c173184c1d8dbdd3fa7d1;p=platform%2Fcore%2Fuifw%2Ftts.git

Move creating AudioStream instance when playing tts is requested

- Issue:
At booting time, there is a case that focus server is not ready.
Because focus server is not ready, initializing TTS engine is delayed with blocking a main thread.

- Solution:
Initializing AudioStream is moved to be invoked when playing TTS is requested.
