How to Play Video through Chromecast but Keep Audio on Your Computer

Chromecast is very intuitive and easy to use, most of the times. There are some difficulties with it which aren’t addressed enough, even by official Google support. Many users have a problem with splitting up video and audio on the device.

You can actually keep audio going through your PC speakers, while the video is playing on your TV. You can also do this with mobile, and this article will show you the exact steps that you need to take to make it work.

Split Video from Audio on Your PC

You need to be really cunning and trick your Chromecast for this to work. Essentially, you will be using your computer speakers and your computer’s speaker and microphone inputs. However, you will not record anything with your microphone, and you don’t need an actual microphone for this to work.

You will only use the microphone playback to play the audio from the media you’re casting through your PC speakers. Here’s all you need to do:

  1. Turn on your PC. This is important because your PC has to stay on for this to work.
  2. Plug in your PC speaker in the appropriate audio jack (speaker out, color green).
  3. Plug in the Chromecast audio into the microphone jack on your computer (color pink).
  4. Have your audio manager up (Realtek or something similar) and running.
  5. Set the playback volume to 50%. Your Chromecast audio will then play normally, but the sound will be played back through your computer speakers.

This method was tested and proven to work on Windows 10 using the Realtek HD Audio Manager. You can try it on your PC and see if it works. There is no reason, however, why this trick wouldn’t work on a Mac, as well. Finally, if this fails, you can refer to the next method.

Split Video from Audio on Your Phone

You can stream Chromecast video on your TV but push the audio through your Android or iOS smartphone’s speaker. You will need a third-party app and we recommend LocalCast. You can download it for free on Google Play Store or the Apple App Store.

This app is safe to use and it works well. You can use LocalCast to cast your own videos, music, and pictures to a Chromecast device. Also, you can stream many online services like Apple TV, Amazon Fire TV, and Roku.

Also, you can cast your games from an Xbox One. The feature you will need for this task is the Route Audio to Device. This option will allow the audio to stay on your phone while you stream anything on Chromecast.

Here is how to do it:

  1. After installing LocalCast on your iPhone or Android, open it.
  2. Tap on the Cast option in the bottom left corner of the app and the app will connect to Chromecast.
  3. Choose the video you want to play and click on Route Audio to Device within the player.
  4. Finally, sync the video and audio using the app.

More About LocalCast

LocalCast has a very small developer team and it is a very useful app. It is supported by ads and it has in-app purchases. The only restrictions are that you need to be at least 17 years old and that you have unrestricted web access to use this app.

Before installing LocalCast, make sure to update your phone’s operating system to the latest version. According to the dev team, the app works better on Android devices than it does on iOS devices. Still, this app is a great tool and it is definitely worth checking out if you have issues with splitting Chromecast video and audio.

Separate Ways

Sometimes you need to have some privacy while streaming. Also, if your TV’s speakers aren’t working, you’ll need to push audio through another set of speakers. LocalCast is a great solution if you decide to enlist your smartphone’s speaker for the job. You can also use your computer’s speakers if you want more power.
