Screencast / capture / Recording can't get it to work with audio

Okay I am still noobish when it comes to aspects of Arch i've used it awhile and it works for what I've set up so far I am wanting to do some screencasting on my laptop and it is proving to be a pain. First I installed RecordMyDesktop which just didn't seem to work so I tried simplescreenrecorder which I can get to work but it has no audio and seemly no errors either which kind of surprised I guess because it is producing a file that plays it things everything is going to plan.

Any advice ? Has anyone had this problem before ? Or is there a more nooby friendly screencast.

Thanks for your time.

For RecordMyDesktop

Change DEFAULT to pulse in recordMyDesktop: Advanced button > Sound tab > Device

using PulseAudio Volume Control

sudo pacman -S pavucontrol

Open the Pulse Audio Volume Control dialog: Applications > Sound & Video > PulseAudio Volume Control
Open recordmydesktop

Once you start a recording, in PusleAudio Volume Control goto the Recording tab and change the recordmydesktop entry to 'Monitor of ....'

I second what @Malkymder said, this really works. However, please note that you will have to use PulseAudio in order to apply this method -- that is, if you're an user of pure alsa you would have to update your audio configuration.

Also, make sure to check the volume level of the recording -- either on pavucontrol too or on alsamixer, for example.

For echo cancellation you can add this to /etc/pulse/default.pa

load-module module-echo-cancel

or

load-module module-echo-cancel aec_method=webrtc

But i've never tried it with a screenrecorder

Thanks seems to have nailed the background noise now.

It's rather quiet tho does it have a way to boost up the volume?

On the PulseAudio Volume Control > Input Device tab just raise the volume past 100% if necessary
