How to have live guitar coming through computer speakers


A few days ago I found out that if you opened a music track with AlsaPlayer whilst watching a film using GnomeMPlayer the audio for both would come through my speakers and it got me thinking.
Does anyone know of a way/program that would allow me to watch a film and at the same time allow the output of my guitar/preamp to also come through my speakers? N.B. I'm not interested in recording just live output.
I've tried to use JACK but qjackctl doesn't work (dependencies?).
The default sound control has a mic slider but which doesn't respond: sGMixer does allow the slider to move but I still can't hear any sound.
Also would there be any specific program that would be required to hear it (neither sweep nor mhwavedit appear to have setting for input).
Any thoughts would be much appreciated.

N.B. I'm using Puppy Lucid.

J.

To do live mixing like this you will need (I really mean it) jack. And, of course, all the involved pieces will need jack support if you want to mix volumes and control everything from a central piece. You must also make sure that your media player is using jack for the sound output and not alsa, pulseaudio or something else.

In some hardware jack might need exclusive access to the device, that means that jack might not work or might work incorrectly if there's any other program using the alsa backend at the same time. So, configure everything to use jack.

I am not expert in sound, and it is a which current status in linux scares me. You should either use a distros that's designed with jack in mind as said above by someone else or seek advice for the concrete problems in separate threads (one for jack, another for qjackctl, etc.).

Might need something like the Line6 UX2. I think there is support in the latest 10.10 and some others. There are older and earlier supported devices.

I did try to connect my guitar straight to the input but it is an impedance deal and doesn't work unless you have one of the very few electronic type guitars with that special out.

Whilst researching this I happened across Puppy Studio which has integrated wineasio and jack support plus rt kernel. I've installed this but haven't yet had a chance to see if it works.
Many thanks for the replies.

P.S. By the by have just seen that HJSplit is now available for linux and works fine.

Talking Problem Solved...Duh!

Found an easier way.

Came across this. Connect guitar/pre-amp output to one and the other output into computer. Speakers go into female socket. Works fantastically well although the sound does drop a little when both on so you need speakers with independent volume control.

Tascam has nice external soundcards with jack inputs for intruments and even XLR microphone inputs with phantom power for a democratic price of arround 100 bucks.
You have volumes on the sound card itself to 'route' your inputs to your outputs without having to configure anything in your OS.

Haven't tested mine under linux yet but under windows no special drivers are needed so I guess linux won't have troubles working with it.
