How properly install audio_common package?
Hello, My ros package uses audio_common package and even though I installed it with the command: sudo apt-get install ros-kinetic-audio_common I keep getting below warnings about soundplay.py. Please ignore the error in my log as it is another story.
odroid@QT05:~$ roslaunch rehabilitation_framework Exercise_Launcher.launch

Which warnings are you referring to here? I see a nr of them, and some of them are harmless (the naming convention one) and others are perfectly explainable (the ones about "no node subscribed":
sound_playshut down just before that).Please clarify.
It looks like the other errors in your launch file are causing premature shutdown of the sound_play node, which is causing the sound_play errors.
These warnings:
Well, looking a few lines up from those lines, you can see:
so the
sound_playnode already exited. The warning seems correct: it is not running any longer.I see, so the problem is that it exits even though it is not told so.
The
sound_playnode exits because roslaunch terminates it. roslaunch shuts down because your node crashed:================================================================================REQUIRED process [rehabilitation_framework-3] has died!
