Line 6 Pod X3 Functionality

I have not tried this, but I found these instructions here. The link is a couple of years old but the software is still there.

First, some build tools are installed, such as Subversion (svn) for version control. Subversion then pulls the latest stable version of the driver from the Internet and places it in a separate directory line6usb. The next step is to build the driver and install it. If everything works, feel free to remove Subversion and the other build tools.

sudo apt-get install gcc make subversion alsamixergui linux-headers-generic
sudo svn co  line6usb`
cd line6usb
sudo make install

Then you have to find your soundcard with:

cat /proc/asound/cards

This tells you how your Line 6 device viewed by the computer ('hw:' number). Replace 'hw:1' with whatever shows up for your sound card when you type:

alsamixergui -D hw:1

You HAVE to turn the 'monitor' slider all the way down or things will crash (unless the 'svn' site has a newer version that fixes this).

In case someone needed an up-to-date link, here's a link to the repo:

svn co  line6linux-code

svn can be installed by

sudo apt install subversion
