I have a QR code set up to play a video.
It is pointing to an MP4 file, which works fine with sound when navigating to this using safari on the iPhone.
However, when I use the QR code to view the video on the iPhone the sound isn’t working.
Here are the links for reference.
Video file: http://www.remarkablegroup.co.uk/temp/prokill.mp4

Additional information
I created the QR code using this online generator: http://qrcode.kaywa.com/
All I did was point the QR Code directly to the file name so that it would use the phones built in functionality.
Most QR code readers have a built in browser which they use to display web pages, and in this case presumambly, videos. The problem is most likely with this built in browser.
Depending on the reader, it will probably have an option to open the URL in Safari instead. I would bet that if you did so, the video would have sound.
Which reader are you using? Incidentally, it works fine with Optiscan.
