I just switched out my Targus docking station for the UD-3900. Everything is working great except the volume from my external speakers.
I have a pair of harmon/kardon speakers that CRANK. There is sound coming from them now but it is VERY low.
I have to have everything on 100% just to get what used to be 2% volume.
I have reviewed the Playback devices and confirmed that the active device is “Plugable Audio”.
I have reviewed the Levels table in the Speaker Properties.
I have ensured that my speakers’ volume is all the way up.
Please help! I don’t want to have to return this unit!
