Use My Media and the Windows 10 Alexa App to music from the same computer

Post by bizmodeller »

My Media can be used to trigger Alexa to stream your local music from a Windows 10 computer running the Windows 10 Alexa App.

However, if you are trying to play music from the same computer you are running the Windows 10 Alexa App on, you may receive a yellow failure message:

The error code was: MEDIA_ERROR_INTERNAL_DEVICE_ERROR
The detailed message was: Device playback error.

This can happen for other reasons, eg network connectivity, however, in this specific case, where you are running My Media on the same computer as the Windows 10 Alexa App, the reason is slightly different.

Windows 10 Store Apps, including the Amazon Alexa app, are configured with a loop back exemption firewall rule. This prevents the app from connecting to any local services on your computer, even if they are available to other services on your network. This includes the My Media for Alexa service that is used to stream your local music.

You can disable network isolation mode by running the following from an elevated command prompt (i.e. right click Command Prompt in the Start Menu and click 'Run as administrator')):

Code: Select all

You should only do this if you trust the Alexa app and if you need any more information please see the following for a technical explanation: https://docs.microsoft.com/en-us/window ... n#loopback

Note the above workaround may need to be reapplied after the Alexa app is updated.
