Description Of Issue

My Naim muso 2 will only connect via airplay to Roon. How do I change this? I want to use Chromecast

Hi @Michael_O_Donnell1,

Can you please provide a screenshot of your Roon Settings -> Audio tab? Do you by any chance see the Muso listed under “Networked” zone?

Here you are, yes I do but as an Airplay device:

Hello @Michael_O_Donnell1,

To troubleshoot this network discovery issue, I would recommend starting with the following steps:

A) Perform a full power cycle of your router.
B) Reboot your computer running the Roon Core.
C) Power cycle the Naim Mu-so.

A helpful diagnostic check would be to check if you can see the Chromecast zone using the Google Chrome browser. You can do this by click on the “three dots” menu button and selecting the “Cast” option.


I’m curious, why would you want to use Chromecast for Roon when you can use the Muso as a ‘proper’ Roon Endpoint?

I was also going to ask the same thing. Why use Chromecast when the Muso 2 is fully Room Ready which is way better than CC.

Grouping with other Chromecast endpoints?


Well it’s a good question, but the fact is that when I in stalled Roon and asked it to look for devices, that is what it found and connected to. I see no way of adding the Muso as an endpoint. I am something of a novice when it comes to this sort of thing so I’m grateful for help.

I have a Naim Atom which is similar in connectivity and looks like below. Looks like something in your w10 or
more probably your networkk setup is blocking the proper roon connection

Thanks Ged

That’s really helpful. In fact I think it’s an issue with either my PC or my network. My Android phone can see the muso via Google Home, but the PC doesn’t see it at all, although it can see my two Chromecast-enable TV’s. I’m wondering if it’s because the muso doesn’t play well with Mesh networks, or maybe my firewall.

Thanks John - please see my reply to Ged below.

Hi @Michael_O_Donnell1,

Can you please verify to make sure that Roon.exe and RAATServer.exe have been added to any application firewalls you may have?

These two executible files can be found by navigating to the Database Location/Application folder path.
I would suggest adding it to your Windows firewall by using these instructions and verify if it helps.

I have got Chromecast working finally. I found this link online: It doesn’t quite match my setup but I followed the instructions as far as they apply and then restarted Roon. Voila! there was my Muso. I’m not sure which step helped, though! My network settings already matched those recommended, so it may have been something to do with the Windows Media Player settings. Either that or it’s a coincidence and it decided to cooperate anyway.

My next quest is to add it as an endpoint. Can I do this over a network?

I’m grateful for all the help.

Add it over a network? What do you mean?

I’m sorry, I mean over wifi.

Thanks. I’ve done that, but the folder location in your link is incorrect. The link is: C:\Users\username\AppData\Local\Roon\Application

Post your settings, audio screen again and let’s see what’s showing.

That’s right the muso is showing correctly now.

I hate to be pedantic, but does that mean it’s running as an endpoint?
