I need to use PlayAudio node in a net, but node is not present in hark designer, eventhough it´s code is in the source code folder. I have installed HARK from precompiled binaries before and I was able to use that node, but if I install hark from source it is not present. That also happens with other nodes. Looks like if those nodes where not being compiled. I am using HARK 2.4 for ubuntu 14.04. Any solutions to that?
