Start by seeing if it’s just the particular movie or TV show or whether it happens on other shows as well. If it happens on other apps then it’s likely an issue with your HDMI cable, or your audio settings. But, if it’s only one particular movie or TV show then you should report it to Netflix.
Generally, this is caused by an issue with the internet connection. The Wi-Fi network that the Chromecast or the device that you are casting through the Chromecast is either disconnected, running slowly, or each device is connected to a different internet connection.
Start by testing the quality of your Wi-Fi connection between your Chromecast and the Wi-Fi modem. To do that, test the speed of your Wi-Fi using another device like an iPad, or smartphone. If the internet speed is good, restart your Chromecast device, force stop the app, and clear the cache.
