I've moved on to another solution using ffmpeg which is working very well. You can record either sound from a program or your mic.
I'm using this for now, just copy paste this to your commandline.
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv
It's the x11grab part that gets your screen. There's also parameters in there for stereo/mono, bitrates, screen sizes, etc etc. It records in whatever file tyes that ffmpeg supports with the -o parameter.
Searching for ffmpeg x11grab will bring up youtube videos of examples and explanations.
