Not sure if this is a bug or something I did wrong

But was out filming today, was too busy managing the video to worry about audio, so set the camera to Automatic in the Canon menu, and then ML override off.
None of my footage came out with any sound.
I assume ML override means to override whatever the Canon audio portion decides to do?
So if turned off, should revert to whatever's specified in the Canon menu?
When I looked in the canon menu I could see the audio bars corresponding to noise, so figured it was working.
However I dont think they were working on the ML screen display, which makes sense I guess.
I had an external stereo mic plugged in, video mode, recording in various formats.
I noticed smooth ISO is in there, which is freaken awesome!
It would be nice to be able to set an upper ISO limit though, and maybe incorporate ML overrides so it can go to 25. (I'm sure this is in the works

)
