yup got it sorted now Dunc emailed Go Pro today and got a speedy reply back
Hi Duncan,
The HI/LO sound settings are found in the setting menu. To access the settings menu, press the power/mode button until you see "SEt" on the screen. At this point press the shutter button to enter the settings menu. Once in the settings menu, press the power/mode button to scroll through the different setting options. The HI/LO sound settings should be the third setting right after the frequency setting. The LCD screen will either read "HI" or "LO". Press the shutter button to switch between the two settings.
To exit the settings menu, press the power/mode button until you see "ESC" on the LCD screen. At this point press the shutter button and you will be returned to shooting mode.
If you do not have the HI/LO sound setting or UP/UPd camera orientation settings under the "SEt" menu then you could have our older spec camera which did not have these features. You can update your camera with the attached patch instructions.
Let us know if you have any further questions.
Many thanks,
GoPro Support
