I am running pd-l2ork -2.4.2 20171101 rev.58bc306 on Ubuntu 16.04. My problem is that some of the menu items are not visible in this version of pd. For example, the list of available audio drivers is not visible under the media tab. As a result I have to configure the audio driver (jack) through the terminal every time I start pd. Similarly, there is no 'Find Externals' option under the Help tab. Is this how its supposed to be or is there any way to make these options visible? Also, how do I install external libraries into purr-data without the gui?
