tts action server freezes

[yepw]

Hi, the tts action server works fine in most time, but when I send requests multiple times, the action server seems freezing. To reproduce the error, just launch the server:

roslaunch tts sample_application.launch

Then run rosrun tts voicer.py 'Hello World' for multiple times. On my computer, it freezes at about the 32nd times. While freezing, the sound card seems blocked and cannot play any video.

Maybe it is because of my sound card driver or the sound_play package. Hope you can reproduce this. Thank you in advance!

Thanks for reporting. As I'm already investigating #19, I'll investigate this while I'm at it.

Quick update. I was able to repro this, but am not able to investigate within the next week.

Looked into this a bit today. It looks like this is an issue with the soundplay node which this package uses to play the audio files it gets back from Polly. We've opened an issue on that repository: ros-drivers/audio_common#125
