Always start launch file with robot_upstart .but ,today,when my microphone lose,i stopped the service installed by robot_upstart,then restart the service,but microphone not work.I don't know what happened with this,because when i start the launch file with roslaunch command line,it work.Then restart service still not work.I just cannot start the launch file with the service.And the service stop not clean,roscore always running.
reboot machine,this problem disappeared.
