Cast with Google Chrome

Hi

When i use Google Chrome and cast my pc desktop to Nvidia Shield Tv i cannot get any sound from MB.
All other apps and programs ive tried cast the sound. Is there something i can do to fix this?

Update:

Reason this did not work was because i had chosen external audio interface in MB, when switching to primary sound driver its working.
