Google Nest Community

I've got support ticket for this problem ( Case ID [9-############2496], Google Nest Customer Care Team), Can you share any new information?

I have exactly the same issue only when i enabled "Surround" sound option. I believe this is known & unresolved issue and I'm waiting for google to handle this problem.  https://www.googlenestcommunity.com/t5/Chromecast/Chromecast-with-Google-TV-Aud...
