correction:

File "/home/pi/RetroPie/splashscreens/video/pistation.mp4" not found.

not sure why a "space" appeared the initial log dump

Got it working! :) Thanks!

Hi again,
Sorry about that, after entering amixer -i the output is amixer: Mixer default error: No such file or directory and entering amixer -l just gave the above error when I thought you said amixer -1,

And would you have any idea about how I would even read the boot/config.txt file

Thanks
