Just got my pi yesterday (model 2 b)
installed retropie and retroarch emulators, and it emulates just fine, minus a lack of audio through hdmi.
Is this a setting I need to changer per emulator? or is this a change that can be made to the /boot/config.txt ?
if it is the later option, I am unable to save changes to that file using the “sudo nano /boot/config/txt” command. How would I enable write permissions for this file?
Thanks in advance,
