This article provides the information on "Venue 11 Pro default audio output changes when docked and connected to either a HDMI or DisplayPort connected display with headphone output jack and may result in no audio".
When not docked, the default audio output for a Venue 11 Pro tablet is the internal speakers.
If the tablet is docked in a Venue desktop dock with an HDMI or DisplayPort connected display with headphone jack (U2713H for example), the default audio output will change automatically to the HDMI or DisplayPort connected device, regardless of any speaker configuration on the device.
If the Display has no internal speakers or has no speaker bar attached, then a no audio condition may be encountered until the default output is changed back to the internal speakers of the tablet.
The Realtek/Intel audio device drivers check for HDMI/DisplayPort audio devices installed in Windows 8.1 and if detected, Windows 8.1 will automatically make the switch to the HDMI/DisplayPort audio device.
If the displays have no speakers and headphone output jack, then the switch will result in a no audio state until the default audio device is manually changed back to the internal speakers.
Right click the volume speaker icon in the systray next to the date/time, then select Playback Devices. Select Speakers/Headphones and click Ok.
