I use Ubuntu Studio 18.04.3 (with the additional ppa backports to get LTS) in three desktop PCs and one laptop.
But, one of the desktop PCs was sequentially upgraded from old versions up the today last version. In other words, in this PC there was not a "full clean" installation.
As the three desktop are exactly the same machines, I suspect that a lot of audio problems I only have in that specific PC are related with the fact it was not a "full clean" installation.
Can I automatically reset and back the system to the original "full clean" installation, without to have to use the Live DVD way?
How?
I'm talking about some automatic way to full erase all the apps and libraries from the old versions whith some compatibility problems with the last version.
