audio/video help???

[gdv]

I have a small HD camcorder that runs on 2 AA batteries...  It goes thru those REAL FAST...  So I made an adaptor to fit into the battery compartment and attaches to a wall transformer producing 5v.  Of course the batteries are 3v combined...

Now the question...  The camcorder does work with the video fine, but I do not get any audio???

When I put the AA batteries back in, everything works fine, video AND audio...  Can't understand why a couple of volts 3 to 5 makes a difference in audio...  How do I solve???

HELP!!!   

TIA,
George

Why not buy rechargeable batteries?

Thanks for comment...  I've tried that too... They go even quicker than the alkalines...

If you think it's really just the voltage difference why not grab a 3v regulator and add that to what ever adapter you've cooked up.

Also, if it really eats batteries that fast, maybe current is your issue, not voltage. Is it possible that your power supply isn't supplying enough current to the camera? I know a lot of those 5v cell phone chargers can't even handle 500mA.
