That's why we have support forums, so that more experienced users can
help new users with teething problems. :-)
It's one of the things that I really like about Linux - there's a
sense of  community and people are willing to help each other. So much
of Linux is built on cooperation and collaborative effort.

The problem is not only Linux.

To do serious audio work on Windows you are likely to need to install
a third party (closed source) audio system called ASIO (from
Steinberg), or the freeware alternative ASIO4ALL. You may also need to
find and install ASIO drivers for your audio device. Then you will
probably need to mess around setting up the buffer and port settings
so as to get your software to work in a reasonable fashion.

Even when all that is done, you will still have the problem that
non-ASIO applications will not have access to the sound system because
ASIO grabs exclusive access.

At least on Linux, pulse-audio-module-jack provides a fairly simple
solution to shared access to the sound card when running Jack.

Good documentation goes a long way to making these issues easier to
deal with. There are plenty of opportunities for users to be involved
in documentation.
