Using a pen drive to boot. No sound in any emulator. Tried to pick audio device and just hangs on every PC I’ve tried. Also does not allow Xbox or PS3 controllers to be used.
Try editing retroarch.cfg for the audio problem. See this thread for the steps you have to take. https://github.com/libretro/Lakka/issues/108
Perhaps your usb ports are not detected. The Xbox PC Cotroller runs fine on X86_64. I am using a MSI Probox23.
