  • Ethan
    • How hard would it be to expose a little more debugging information (such as what sound device it's trying to use)? Hardy seems to have some bugs related to Pulse audio and on my machine (which has issues with sound not infrequently) I can't get any sound out of "rosrun sound_play test.py". I'd imagine this is an issue with my system specifically, but given that Hardy is a common platform for us this may not be such an exceptional situation.
  • Josh
    • No documentation on the code API makes it hard to review
    • SoundHandle doesn't seem to be a handle to a sound, rather it manages any number of sounds?

    • Given the current API, is this correct usage?

SoundHandle sh;

I would prefer something like:

SoundHandle sh = play_sound::say("blah");

sh = play_sound::play(1);
  • Can multiple sounds be played at the same time? What will this do:
