Describe the issue

Hello Team my Cambridge Audio Melomania P100 headphones doesn't play music when connected via USB wired.

Describe your network setup

Roon Server is on my MacBook pro services and local library is connected through wifi

If your MacBook is running macOS 15 Sequoia, try this:

Roon 2.0 build 1480 not detecting audio devices on Mac mini (ref#LKGPIF)

macOS 15 messed up security settings for quite many people, leading to device discovery issues. Lots of threads about this on the forum. Try this, it usually helps: Navigate to macOS System Settings > Privacy & Security > Local Network , and make sure Roon is allowed. If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.

Not working for me. I still get message: “too many failures. stopping playback”

[Suedkiez (Just a fellow user like you)]

Sorry, I missed that your device is connected by USB, not network. In this case, may be another one of macOS 15‘s tightened security checks. Try the second one in this post, „Allow accessories…“. Not sure if it helps but worth trying:

Permission error when setting up external drive in Roon (ref#7TVTW9)

Hi @Clifford_Brown, I’m assuming this drive shows up in Disk Utility? Can you access it in Finder? The Sequoia update has changed privacy around network access and device access. As an aside, for due diligence, in System Settings → Privacy & Security, make sure Roon has Local Network access. Then try this: First, disconnect the device. Back in Privacy & Security, click “Allow accessories to connect”, select “Ask every time”, then connect the USB drive, and select “Allow accessories to conne…

Hi @Roman_Kral,
Thanks for reaching out to us to ask about this. Did @Suedkiez’s suggestion help you?

[Roman_Kral]

Unfortunately no. Roon correctly recognizes my Melomania p100 via usb connection. Despite this, I get error message when I try to play anything.

[Roman_Kral]

playback via usb works with Audirvana Studio. But not with Roon

Hey @Roman_Kral,

Thanks for following up! We’re seeing an error RAAT__OUTPUT_PLUGIN_STATUS_FORMAT_NOT_SUPPORTED when you’re attempting playback. And while the file format seems to be 44.1/16, nothing out of the ordinary.

Are you able to access the zone settings>device setup and review the sample rate options for the P100?

It may be worth checking if there’s a firmware update as well. We’ll be on standby for your reply!

[Roman_Kral]

I have set 24/96 but with no help. Roons keeps skipping tracks, occasionally plays one track in a long playlist, next time skipping too many tracks and shows error message “too many failures, stopping playing”

[Roman_Kral]

I have already installed brand new firmware on my melomania p100, but the issue is not adressed.

[benjamin]

Hey @Roman_Kral,

Thanks for the update!

As a next step in troubleshooting, could you test out enabling or disabling ‘Exclusive Mode’ within the device settings? If it’s enabled, test out disabling it. If it’s disabled, test out enabling and let me know your results!

[Roman_Kral]

Hello Benjamin, thank you for your suggestion. Disabling exclusive mode worked for me. After brief testing, roon plays my tidal tracks through melomania p100 usb mode. Thank you for your support.
