After last Roon update I find that Firestream on Mac no longer functions and throws up the alert that “another application appears to be using UDP port 1900 (SSDP)”. After running the “sudo lsof -i:1900” command in Terminal the result was that Roon was the problem. Any constructive advice would be appreciated.
Hi @fallingforstars,
Good to see you on the community again!
It looks like you’re encountering a port conflict on UDP 1900, which is used by the SSDP protocol, which is essential for device discovery in both Roon and Firestream. Since only one application can bind to that port at a time, Roon is blocking Firestream from using it.
Nothing on the recent Roon update would affect this, so the timing is odd, unfortunately, you’re not able to manually change the SSDP port in Roon at this time.
Are you attempting to use both applications at the same time? You could always move your Roon Server to a different machine, or vice versa with Firestream.
Let me know! 
Hi Benjamin. Thanks for the reply. The timing may perhaps have been coincidental with a Mac update to 15.4.1 but it has been working fine until recently. I only require Firestream to use with a pair of KEF LSXII speakers in a conservatory which allow me to stream specific playlists from iTunes on the Mac via ethernet.
I can of course stream from Roon but Roon has to be actively open and it doesn’t have the iTunes playlists I require. I tried yesterday to add the iTunes XML playlist files to Roon and it seemed to read them but it doesn’t show them in the Roon Playlists section.
Hi @fallingforstars,
When you imported the XML did you enable the iTunes import on your watched folder? This article will show you how to do that. Let us know if you have any more trouble with that.
Yes did that. iTunes playlists still don’t show.
Hi @fallingforstars ,
Is the iTunes playlist at the root of your music directory that Roon is watching? Have you turned on iTunes playlist capabilities in Roon Settings → Edit → iTunes playlists?
Roon still doesn’t see those xml files. I’ve tried re-exporting a playlist out of iTunes (Music) and saving it to the music folder that Roon is watching but it will not appear in the playlist field within Roon.
Hello @fallingforstars.
Thank you for the details. If Roon is not detecting the iTunes XML file despite it being placed in a watched folder, here are a few things to check:
- File Naming
Please ensure the XML file is named correctly. Roon will only recognize files that:
- Are named exactly
Library.xml, or - Contain
iTunesin the file name and end with.xml(e.g.,iTunes Music.xml).
- File Location
The XML file must be saved in the same directory as your media files (not in a subfolder). Roon does not scan XML files in folders that do not contain music. - Enable iTunes Import in Roon
Open Roon, go to Settings > Storage, and click Edit on the folder where the XML file is stored. Make sure “Import iTunes Playlists” is enabled for that location.
After verifying the above, give Roon a few minutes to re-scan the folder. If the playlists still do not appear, try restarting Roon and forcing a re-scan from the Storage settings.
Let us know if it still doesn’t show up after these checks, and we’ll assist further.
Hi Vadim. Still no iTunes playlist appearing in Roon. Have forced a rescan and relaunched Roon but the playlist will not show. I exported one playlist titled Lounge.xml from iTunes and it saved in the music folder Roon is watching but despite this the name will not appear in Roon’s playlist field.
Could it be that my music is stored on a SSD? Where are the current Roon playlists stored? If the iTunes playlists could be copied to the same location surely that would solve the problem?
Hello @fallingforstars,
Could you kindly provide the following information to help us investigate the issue?
- A screenshot of Roon → Settings → Storage → 3 dots → Edit
- A screenshot showing the contents of the folder where your playlists are located, including both the folder structure and the files inside.
This will help us better understand your setup and provide accurate guidance. Thank you!
I have two watched music folders. The one terminating in the ‘Music’ folder contains hi-res music files. The other terminating in the iTunes folder does not contain hi-res files as Apple’s iTunes, or more correctly ‘Music’, does not see certain types of hi-res files anyway and the reason why I purchased Roon - purely for playing hi-res files to a Roon ready speaker.
Hello @fallingforstars,
Thank you for the uploaded screenshots!
It seems my second question may have been missed — would you kindly attach that one as well?
This will help us better understand the situation and assist you further.
Hi Vadim.
Screenshots attached. You’ll notice that in each case after adding the iTunes xml file called “Lounge” it does not appear in the Roon playlist.
Hey @fallingforstars,
Thanks for the additional info!
If you could, please zip up a copy of both the .XML file as well as the folder of tracks included in the playlist for our development team to attempt to reproduce in house? Note that all files will be removed after testing is complete.

Let us know when the upload is complete and we’ll share it with our team for in-house reproduction. Thank you!
