You're best off sticking with the 2.4.22 kernel for many reasons. That's the
version number for the Linux kernel rather than the Debian version (3.1 -
aka 'Sarge' I'd guess)

No, it sounds like your soundcard is more-or-less configured. It would help if
you could generate some useful error messages, Audacity's not the best for
that. You should only have to have capture enabled on the line-in bit of the
mixer and have 'line' selected as input on Audacity. If not you have reason
to suspect your sound set-up. Are you using ALSA?

Rosegarden4 doesn't actually make any sound all on its own AFAIK, you have to
connect it up to a softsynth using Jackd. I use MusE generally, It's much
quicker to get working with and has softsynths 'built in' - so to speak.
Sounds like MIDI is configured ok.

Could easily be a bit of both ... If you have a full Debian system installed
you'll probably already havea fair amount of documentation on your hard
drive. Reading is good :-) Collecting useful looking error messages is also

There are a multiplicity of different ways this can be achieved. Snd & Sweep
do much the same thing and it's also worth getting familiar with command-line
into an xterm is probably the most basic way of achieving the object.
If that doesn't work you have set-up problems.
