Sound from external speakers

I connected the UD-3900 docking station and can’t get sound on my external speakers, Logitech M313

Hi Ramon,

I suspect that you may just need to change the default audio device:

I’ve also contacted you directly via email so I am closing this thread. If you have further questions reply to my email.

Thanks!
