No audio on export

managed to get everything to work. Not sure how since last night everything including video drivers were crashing at every turn. opened it all today and its working barely. however on render 2 main things keep happening when this had no issue before. 1st is using youtube preset render method video has no audio and using any other settings or preset its the same for export no audio. 2nd is sometimes the video won't play in vlc media player. in quicktime player it says video is corrupt. all after export.

Try this, adjusting Resolution, Frame Rate and Key Frames accordingly.

Thanks, I've tried that and it doesn't work.

You listed two problems. Which "doesn't work"?
