Hi, I’ve just built a Picade 8" and have it working but at deafening volume. Also my power button seems to have no effect when i try to shutdown.
The error message I get when trying to configure audio is from the RetroPie configuration menu is:
ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL plughw
lv10: VolumeControl::init() = Failed to attach to default card!
The power button doesnt seem to work at all, no light either.
Any help gratefully appreciated!
