Harrison Mixbus crashes after selecting the Jack driver

Harrison Mixbus is a fantastic piece of software, a modern DAW that gives you the “traditional” analog mixing workflow. But there seems to be a thing that bites with Ubuntu Studio 18.04 and 18.10. I had a problem with Harrison Mixbus version 5 and 5.1 (new update). Harrison Mixbus crashes during the the starting phase, after selecting the Jack driver. Which is strange as Ardour 5.x seems to work fine. This is how I fixed it…

After reading some help pages I found out that there is a suspicious file called ‘csladspa.so’. If you find yourself in a simular situation, you might want to try the following…

Rename the suspicious file called ‘csladspa.so’, located in /usr/lib/ladspa/csladspa.so, by opening a terminal window and enter the following command:

sudo mv /usr/lib/ladspa/csladspa.so /usr/lib/ladspa/csladspa.old

Now try to start Harrison Mixbus again!

If this works for you, you might want to try remove the package called “csladspa”. You can uninstall “csladspa” in the terminal window by issueing the command ‘sudo dpkg -P csladspa’
