Casting audio from Windows 10 to Streaming Stick+ not working.

Thanks for sharing here in the Roku Community, SibeDad.

We appreciate you bringing this matter to our attention; we'd like to take a closer look.

We will forward this to the appropriate Roku Team for further review and investigation. To pass this on to them, we need some essential information to help them locate the root cause of the problem. Kindly provide the following information:

• Roku device model, serial number, device ID, and OS version. (these can all be found in Settings > System > About)
• Tracker ID (when you see this issue occur, press the Home button five times, followed by the Back button five times, and provide us with this ID)

In the meantime, try performing a System Restart on your Roku by going to Settings > System > Power (if you don't see the Power Submenu, skip to System Restart). Also, try performing a manual Software Update on the Roku device you're having a problem with by navigating to Settings > System > Software Update. Thank you for your patience and understanding. We hope we'll sort it out soon.

Please keep us posted so we can assist you further.

All the best,
Emman
