How To Improve Chromecast Audio With External DAC

To improve Chromecast Audio with an external DAC, connect Chromecast to a USB-C hub and link your DAC to the hub. Next, connect your phone or computer and  Chromecast Audio to the same Wi-Fi network. Finally, open the Google Home app and cast audio from your device to Chromecast.

Understand What a DAC Does

There is nothing more frustrating than trying to listen to audio using Chromecast only to have a blank screen appear instead.

Nevertheless, that’s not Chromecast’s only flaw; the device often has trouble with audio quality as well.

It is the job of a digital-to-analog converter, as the name suggests, to transform digital audio signals into analog signals that your speakers can process.

Digital music is the norm when listening via smartphone or computer.

But, an analog signal is required by your speakers to play the music.

An analog-to-digital converter is useful for this purpose. As a result of its superior processing of digital audio signals and reduced noise, an external DAC significantly enhances audio quality.

Choose a DAC Compatible With Your Chromecast Audio

There are a lot of DACs out there, but not all of them are compatible with Chromecast Audio.

It is recommended that you search for a DAC that has either a digital optical input or a 3.5 mm (0.14 in) auxiliary input. Your Chromecast Audio will connect to the DAC via one of these inputs.

To avoid this, you can use a USB-C hub to link a DAC with USB ports to Chromecast, as I will show you below.

After hooking up your Chromecast Audio to the DAC, you’ll have to link the DAC to your speakers.

  1. Connect the DAC to the speakers with a 3.5mm (0.14 in) auxiliary cord if the speakers have an auxiliary input.
  2. If your speakers have an optical digital input, you can use that.
  3. If their plugs are not standard RCA or XLR, then you will need to find a suitable cable.
