Re:Yoga 720-13 USB-C to HDMI: Picture, but no sound

Hi,

 

I have the same problem with usb-c to HDMI adapter, good image but no sound.

Strange thing:  I have the sound with HDMI working perfect some time ago, after some windows updates the sound stop working.

 

Tried everything, like change the adapter, change the cable, reinstall drivers...and now I restore the computer to the factory settings and still not working.

 

Have anyone get this work?

Hi,

 

I've never tried using our USB-C port (on our Yoga 720-15IKB), but I have a Lenovo ThinkPad notebook > connected via USB-C > to a (supplied by my company) Lenovo ThinkPad USB-C UltraDock Gen 2 (40AS0090US) > connected via HDMI to a Samsung Smart TV (used for additional/extended office monitor), and it's always worked beautifully.  Although they're rather expensive on the Brazilian River website.
