If you open the playback devices in the sound icon on the taskbar, you should be able to select the desired output device. It is likely to switch to the digital out when connected with the digital video out.
Surface Pro has no sound when external display is connected

When I have an external monitor connected via the mini displayport on the Surface Pro, there is no sound played through the Surface's speakers. I have plug in speakers into the mini audio out. Does the mini-dp on Surface support audio and is trying to output audio? I'm currently using a mini-dp to displayport cable, and would prefer the option to choose whether the sound is being piped through the mini-dp or continue through the Surface's speakers.

2017-01-06T11:04:19+00:00 Try this - this worked for me:
- Right-click Playback Devices
- Right-click the selected output device, select Properties
- Advanced tab
- Change the Default Format, keep trying until one of the select bit/Hz works.
I think that you will notice that success is only temporary. I've been down this road before, thinking that changing some setting is the silver bullet we've been looking for. However, the problem has always returned after a day or two.
The only solution that has worked consistently for me is inactivating/reactivating the Intel audio driver after connecting the screen (as described earlier in the thread), but it is quite clunky.
