I just purchased the Pro8 Docking Station and it seems to be working great with my Venue 8 tablet running Win 8.1, however, there is no audio. I have read about this problem with Windows 10, but I’m only running Win 8.1. Has anyone else experienced this? There is no audio from the tablet’s speakers or from the tablet’s audio port. I do however have audio from the audio port on the dock, but would prefer not to always have to use headphones or external speakers. USB Multimedia audio device comes up as default and the signal indicates that it is playing, but there is no sound.
I suspect you just need to change the default audio output:
Let me know if that doesn’t help!
