No sound in Teamviewer in my Xiaomi from my Windows 7 home PC

I'm using windows 7 in my home PC and I connect to it using teamviewer 14.1.87 downloaded from Google Play Store, in my xiaomi when I'm outside and need to monitor my PC. But there's no sound relayed to my xiaomi, even when I tried playing random youtube video.
