Lego Batman 2 very quiet - am I stuck with it?

Was able to download Lego Batman 2. I works fine but the sound of the game is very low (even with the console volume turned right up).Has anyone else experienced this or can I be pointed to one with a louder version?Thanks

Plug some PC speakers in the ear phone jack, you will have super sound in no time.Kind of like these ones http://mp3portableplayers.net/tag/wireless-pc-speakers/ are simlure.Samples ;)

Cheers but the game is for my 5yr old boys and they wander around with their DSi's so that's not practical.

Possibly it's an actual game issue.
A lot of games have options to change volume. It's possible that the one you downloaded has the default sound low.
Find the game menu and see if you can find a sound option.If that doesn't work or if there is no option, just buy a pear of earphones. Apple ones work fine.

ok, thanks Xenirina, I'll see if I can find a different version to download too
