Salve galera .Estou testando o SimpleScreenRecorder (
http://alien.slackbook.org/blog/a-journey-into-recording-sound-video-in-slackware/ ,
http://www.maartenbaert.be/simplescreenrecorder/ ) tá tudo instalado .O programa grava mas não captura o aúdio .
Chamo ele pelo terminal configuro e em uma parte do log aparece isso :
PageRecord::StartPage] Starting page ...
[JACKInput::Init] Error: Could not connect to JACK!
[PageRecord::StartPage] Error: Something went wrong during initialization.

Como fazer o JACK Audio Connection Kit funcionar com o programa .(
obs --->testei o SimpleScreenRecorder no Gentoo , e ele funciona normalmente )
Obrigado pela atenção , salve !!!
Zezão, eu cito aqui o grande amigo AlienBOB pra você:
Unfortunately it turned out that SimpleScreenRecorder was not capable of recording my Slackware desktop’s sound, and therefore game videos are silent.
That is a show stopper… apparently you need a sound server like PulseAudio in order to record the audio as well. I am not prepared to install PulseAudio on Slackware – as you are well aware, this is a personal issue I have with the PA author and the way he writes code. So I investigated further, and found out that the unreleased GIT sources of SimpleScreenRecorder support JACK as a new sound source next to ALSA (and PulseAudio). I built the program from its GIT sources and then went on to learn about JACK Audio Connection Kit. I knew that JACK is primarily used by audio professionals and musicians because of its low-latency core design. But as it goes with versatile programs, it is inherently difficult to grasp its concepts and complex to configure. But I persevered and ultimately found a way to configure JACK on my desktop, and reconfigure my ALSA setup so that all the programs that I use can still emit sound, and SimpleScreenRecorder is now capable of recording video and audio! I put a demo video online which I recorded for the intro sequence from the Metro: Last Light game.
(...)
My next post will be about how I built and configured JACK, and what I had to change in my ALSA configuration so that for instance Steam games (using SDL for audio) and MineCraft (using OpenAL for audio) would still make sounds.

Como AlienBOB é um cara legal, ele já disponibilizou os SlackBuilds necessários para instalar o SimpleScreenRecorder:
http://www.slackware.com/~alien/slackbuilds/simplescreenrecorder/build/ - para compilar o programa em si
http://www.slackware.com/~alien/slackbuilds/ffmpeg/build/ - para compilar o ffmpeg, uma dependência do SimpleScreenRecord
http://www.slackware.com/~alien/slackbuilds/jack/build/ - para compilar o JACK, a outra dependência.
