No Sound on Android from Windows 10

Hello Together

I have a Samsung Galaxy S8 (Patch Level: 1. October 2017, Android Version 7)

Windows 10 1607 is installed on 2 PCs (With Patches from December) and TV 13 installed. I connect from the Phone to Windows over the IP in the same Network.

On both Tests i can't get Sound on my Phone. On the iPhone all works. The TV Android Version is 13.0.8183 CL.

I have no idea what's the Problem is.

Has anybody the same Problem?

What i will try now, is to install Windows 10 1709.

Edit:

- Windows 10 1703: Same Problem

- Windows 10 1709: Not my Client but same Problem

- TV 12: Same Problem with Windows 10 1607

Edit 2:

- Over the normal TV ID it works but not over the IP-Address.

- Tested also with 2nd Android Smartphone but no luck.

@support-Team: Can you have a look at this (Reproduce it)? I'm out of ideas. Mabye it a Problem with UDP/TCP.

Many Thanks

Best Regards and a Happy New Year.
