Low output volume on external speaker. Any idea why?

[vertigo89]

I got an external speaker for my tablet to use for navigation while driving (lots of road noise, so i need a lot of volume), but the problem is that my tablet, the venue 8, doesnt seem to supply enough signal to the external speaker. The speaker itself is powered externally, so its not a power issue, per se, it just doesnt get nearly loud enough (probably about the level of the mediocre tablet speaker itself). Also, volume booster apps appear to do nothing. Anyone know what could be causing this?

It could be limited to the volume safety mode.
Here is a link to the dell forums to help you switch it off if you have two or more users:
