Why does Netflix keep losing sound?

One of the most popular apps people use to stream film and video is Netflix.

Chromecast is used to project the app from a smaller device like a tablet or mobile phone to a TV or other larger device.

The Google Home app likes to use stereo sounds and this could be affecting your sound from Netflix.

To stop Netflix from losing sound try the following:

Locate the subtitles menu > Change the audio setting to “stereo”

This should improve the sound quality for better listening as a result.
