Not able to run gazebo #358
Comments
Hmm... what platform are you running on? |
I have Ubuntu 20.04 on an hp laptop. |
I think it looks like an error related to a sound card - it's possible that something in gazebo is trying to access it? Can you share the command you're using to run it and which image you're trying to run? |

Hello,
I am using humble-gazebo image and wasn't able to run gazebo. I get the following error and could resolve it

I am sorry if this is a stupid question to ask
