Call me dumbI use my 4.1 flashed to 5.1 pro for very little, its filling the roll of media server.Still have the original GT120 card installed.I do recall reading some time back that this card did not support audio via display port. Well I figured this was something new and i'd give try it.Ran the command then rebooted, Now I am in a reboot loop as it tries to load.I can get in via safe modeSomeone have an easily way to undo remove this extension?decided to try the display port to HDMI and it completed the boot fine.No audio, then shut down and re-tried the dvi to hdmi, again completed the boot this time fine, no audio from that gt120.Not sure why after booting safe mode and exiting it now boots fine with the extension.Nonetheless, anyone want to help with the removal undo this mod?
