No sounds I heard, when I tried openal.world with gazebo5.

Hi. I tried to use openal.world with gazebo5 on Ubuntu 14.04, but I heard no sound, when a cube touched the ground plane. After I found some past gazebo tracker documents, I tried moving the sphere which has a microphone at several places around the cube. But it did not give me any effects.

Then I wrote a wrong sound filename in openal.world on purpose. But any error message did not appear from gazebo, although I run gazebo with verbose option.

......
    <audio_source>
      <uri>file://media/audio/cheer-.mp3</uri>
      <pitch>2.0</pitch>
      <gain>30.0</gain>
      <loop>1</loop>
      <contact>
        <collision>collision</collision>
      </contact>
    </audio_source>
......

Now I am guessing that the sound system is not working in gazebo5. If it is true, please tell me which version of gazebo I can use the sound system. Or does it require some additional package for the sound system with gazebo5?

Thanks.

Are you sure you have OpenAL installed?

sudo apt-get install libopenal-dev

Thank you for your help.

I tried your suggestion, but it was no effect. I'm searching how to check OpenAL can work in my machine. Do you know some tools to check OpenAL?

Thank you.

Did you install Gazebo from debian packages or did you build it from source?

No, I did not install Gazebo from debian packages , I did not build Gazebo from source. That is the point of this issue? Do I need one of them?

OpenAL is an optional dependency for Gazebo, which means you might have a version of Gazebo which doesn't support it.

It may be the case that the debian packages distributed (the ones you get when you install gazebo using sudo apt-get), didn't include this optional dependency. So the only way to get it to work is to install OpenAL as I said before, and then build Gazebo from source, see this tutorial.

@j-rivero , do you know if OpenAL should work in Gazebo5 debs?

Which version of gazebo do you recommend to use the openal library? Is version 5 builded from source enough?

I recommend you install the latest long term support version, which is 7.

Building Gazebo7 was done.
And I need one more step. Now, I received an error : "No FFMPEG audio decoder. Missing FFMPEG libraries.".
Then I installed ffmepg with following commands:

sudo add-apt-repository ppa:mc3man/trusty-media  
sudo apt-get update  
sudo apt-get install ffmpeg  
sudo apt-get install libffmpegthumbnailer4 libffmpegthumbnailer-dev  

But the same error massage I got again.
Could you help me?

Thanks.
