mhacontrol unexpectedly resets jack connections #11

Yesterday, during the preparation for the workshop, we found that the GUI (mhacontrol) in version v4.5.5 unexpectedly disconnects the JACK connections from and to the MHA when connecting to the MHA via network. This was on Windows using GNU/Octave 4.2.2. (or maybe 4.2.1).

We then tried openMHA version v4.5.4 which shows the expected behavior, leaving existing connections untouched.

In the directory where mhacontrol is running there should be a file named "mhacfg_.mat"
Does the error still occur after you deleted this file?

Cause is a function of the connection dialogue to save the Jack connections that you make for all eternity. We will fix this by not saving the connections to a file in the next release.

This is fixed in release 4.5.6 by not calling the audio connection manager from mhacontrol.
