Dear Gabriel,
We are very sorry for the inconvenience with the node installation.
To enable PlayAudio, please add the following option for configure when compiling the sources.
–enable-playaudio
This requires libsdl2 so please install beforehand with the following commandline command if it is not installed.
sudo apt install libsdl2-dev
Thank you very much for pointing this problem.
We would appreciate if you could tell us what nodes also not installed.
We would like to fix the problem and update the documents accordingly.
Sincerely,
HARK Support Team
