Which plugins work on the x86 platform?
I think that you will have to contact the author of the plugins that you are interested in. Devices on which the plugin has been tested should really be included in the plugin description (I have altered the directions on the top of the plugins page to reflect this, but it will take a while to filter through).
Which plugins are you looking for?
CD player and Brutefir
If this works for you, you can install brutefir
sudo apt-get update
sudo apt-get -y install brutefir bs2b-ladspa
Not sure about the CD player plugin though.
