You can setup Chromecast Audio from any one of the following devices:
- Android phones or devices with Android Jelly Bean 4.1 or later;
- iPhone or iPad with iOS 7 or higher;
- PC with Windows 7 or later;
- Chromebook with Chrome OS 28 or later;
- Mac computers with Mac OS 10.7 and later.
In this guide, Android device is used to show you how to setup Chromecast Audio.
To setup Chromecast Audio, please follow these steps.
Step 1: Connect your Chromecast to the speaker or AV receiver
Before you try to setup Chromecast Audio, you need connect Chromecast Audio to the speaker or AV receiver
You can use one of the following 3 audio/optical cables to connect Chromecast Audio to the speaker or AV receiver:
- 3.5mm stereo cable (which is included in your Chromecast Audio box) for analog output.
- 3.5mm to RCA cable for analog output.
- Mini TOSLINK to TOSLINK optical cable for digital output.
If your speaker does not support any of them, you cannot use it for Chromecast Audio and therefore you cannot proceed to setup Chromecast Audio.
Anyway, almost all speakers and AV receivers support at least one of the three input options.
If you speaker or AV receiver supports digital input, try to use the third option which delivers the best audio quality.
Step 2: Power on Chromecast Audio and your speaker
You need connect the power adapter to Chromecast Audio through the micro USB port and plug the power adapter to a electric socket.
Please try not to use the USB port in your AV receiver. You may mess up the AV receiver!
You need power on the speaker or AV receiver and adjust the volume to normal level.
If possible, you can try to play some music on the speaker to make sure it works if you just grab the speaker from the basement.
Step 3: Find Chromecast Audio devices
Now, in your Android device, start Chromecast App.
If you haven’t installed Chromecast app, get it from Play store.
In Chromecast App, tap Devices as shown below.
This will list any Chromecast devices nearby. The list include Chromecast devices that are ready to use and new Chromecast devices.
For example, as shown below, new Chromecast Audio device (named ChromecastAudio0559) was found.
You must setup Chromecast Audio device so that you can use it.
Please note, for each Chromecast Audio device, you only need setup it once. After you setup Chromecast Audio device, it will be ready for use from all other devices. It is NOT necessary to setup Chromecast Audio devices on all your mobiles phones or tablets.
Tap Set up as shown below.
You will be brought to a new setup page as shown below. Tap Set up again.
Step 4: Play test sound
After tapping set up, your Android device will try to connect to Chromecast Audio through WiFi Direct.
It is not necessary to manually enable WiFi direct on your Android device because Chromecast App will do this automatically for you.
You will see the following message on the screen as shown below:
Connecting to ChromecastAudioXXXX
XXXX is 4 digit random number for your Chromecast Audio.
After the connection is established, you will be asked to play test sound to Chromecast Audio.
Tap Play test sound as shown below.
If you hear the sound from the speaker, tap “I heard it” as shown below.
You can tap the big speaker icon to play test sound again.
If you cannot hear any sound, make sure the speaker is powered on and the volume is high enough.
Step 5: Change the name of Chromecast Audio
Now, if you are not happy with the name of Chromecast Audio, you can rename your Chromecast Audio.
Of course, you can change the name of Chromecast Audio at any time in the future through settings.
In addition to changing the name for Chromecast Audio, you can also enable guest mode if you want.
If you do not want to send Chromecast Audio usage data and crash report to Google, you can uncheck the option as shown above..
Tap Set name as shown above to proceed.
Step 6: Provide WiFi info for Chromecast Audio
After setting the name for Chromecast Audio, you will be asked to provide WiFi info for Chromecast Audio.
Chromecast Audio will try to use the WiFi network which is used by your Android device now.
Select the WiFi SSID name from the list and provide WiFi password as shown below.
Then, tap Set network as shown below.
Please note, Chromecast Audio will save one, and only one, WiFi network. If you change wireless router settings, or change WiFi network, you need factory data reset Chromecast Audio if you cannot access old WiFi network.
Step 7: Update Chromecast Audio firmware
Chromecast Audio will update the firmware automatically when it connects to internet.
If update is available after you setup Chromecast Audio, it will try to apply the update before you can use it to cast.
When you update it first time during setup, it will play some demo videos. You can tap skip to skip it.
Anyway, it should not take too long to get the update. Of course, this depends on your internet connection speed to Google servers.
If it takes too long time, you can simply power off Chromecast Audio, wait one or two mins, then power it on again. Your Chromecast Audio will try to update again.
Step 8: Ready to cast
After you successfully setup Chromecast Audio, you will see the Ready to cast behind the device as shown above.
This means the Chromecast Audio is ready for you to cast audios.
You can tap gear icon to change the settings for this Chromecast Audio device.
