Windows 10: Audio lags behind video when streaming on Xbox One S

I stream video from my Windows 10 PC to my Xbox One S using the Films & TV app. But audio signal always lags about 1.5 seconds behind the video. I connected my computer and Xbox One S to the network via a Cat 6 Ethernet cable. The broadband speed is 100mbps

Xbox one game streaming lag

When I test the game streaming function on the Xbox App I get a 'very high' result, but when I start streaming and play the Xbox games on my laptop I get a lot of lag. Sometimes the App even tells me I have 'network quality problems' even when I set the
quality on 'low'. Tried to play COD AW multiplayer and that's just not possible because it feels like I'm always 1 second behind. Yesterday I had some fun playing 'Defence Grid' streaming to my laptop but it stutters both in video and audio.

Is the lag normal or is there anything I can do to make it stream smooth ?

Been to the trouble shooting page and nothing on there that's helpful to me. I used to have a wireless network and the streaming then was even worse, it was unplayable. Then I bought an ASUS AC router but that didn't help. Then I was told that I needed a
wired connection what made me feel really disappointed.

Quote from the
promotion page :

Stream your Xbox One games to any Windows 10 PC in your home
Play Xbox One games in more places at home on a Windows 10 desktop, laptop or tablet. With an Xbox controller and a laptop your Xbox game collection follows you from screen to screen, so you can play Halo in your bedroom,
kitchen, or as far as your Wi-Fi will go.*

*Stream to one device at a time with supported games.

"As far as my wifi goes" ?

Last week I went to a lot of trouble to make a decent wired connection in my house and everything runs great except for the Xbox One game Streaming.

It lags

 

Lagging in xbox app streaming

I am having a problem with game streaming on the xbox app. When on the xbox interface, it works fine with no lag, but when I start playing a game, the stream begins to lag. The most confusing thing about this is that it causes my computer to become unresponsive;
when I hover my mouse over the stream, it would take 10-30 seconds for the interface to appear, and when I press the "stop streaming" button, the pc would sometimes freeze. It is also important to note that this is a very recent problem.
