Description of Issue

it’s been a rough journey with Roon so far.
my set up - macbook pro, KEF LS50 wireless speakers connected to mac with usb, and music on Tidal.
it was playing fine and suddenly it stopped connecting with the speakers, saying that no audio device was found. it now continues to say - no audio device found. my speakers are working with other apps on the mac but somehow roon is unable to find speakers.
I have tried everything but nothing happened.
the mobile remote app freezes again and again needing to be restarted.

I am so so disappointed. Kindly assist

@arun.psych.au, can you share a screenshot on what you experiencing? Do you see the LS50W in Roon’s Settings → Audio tab, and if so is the LS50W Enabled? Or is the LS50W not showing at all?

It is not showing LS50W at all in the audio device . it only shows macbook speakers and sonos arc from the living room but not the usb connected speakers. I can share screenshot later after reaching home. When I click audio -I see - ‘no audio device found’ on the bottom and macbook speakers and sonos arc with a tab - enable. LS50W is able to play youtube on mac so its working fine, just that Roon is unable to find it.

Hi @arun.psych.au,

Thanks for writing in! Sorry to hear you’re having issues with your LS50W.

As a follow-up, do you run into the same issue if you connect in a wireless format? I realize this effects playback options, but temporarily, this would be helpful information to know.

I also noticed that your Mac is on Sonoma - there is known audio issues that may be helpful to review:

If you remove other options from your audio/MIDI settings and just hold on to the system output and the LS50W, does the issue still occur?

Let me know, thanks!
