Yes, you can. After the WiiM Mini is signed into Amazon, you can cast up to 192 kHz/24-bits Hi-Res music gaplessly from the Amazon Music App to the WiiM Mini with the Alexa casting.


Please follow these steps to enable the Alexa casting:

  1. Go to WiiM Home app > Browse > Amazon Alexa to sign in to your Amazon account. Please make sure the account of your Amazon Alexa is the same as the one used in the Amazon Music.
  2. Go to Amazon Music App > Playing UI > Tap Alexa Casting icon to check if the WiiM Mini is under 'Select a Device to Play Music'.
  3. If you can't see the WiiM device, please wait for some minutes. Amazon Music needs some time to fetch a new device.
  4. If you don't get Amazon Music HD/Unlimited, please go to Browse tab -> Amazon Music -> Tap the top right settings icon to turn on Amazon Music HD/Unlimited HD.

Here's a link to a video for your reference.


Note:


If you still can't see your device on Amazon Music app, the issue maybe caused by the different location of the store.
