I am experiencing the same issue, I have the latest Node and a Luxman DA06 DAC.
The USB input noticeably sounds superior compared to COAX, but pops and clicks only using Roon…native BluOS app plays fine.
I bought a lifetime subscription about a month ago and love it.
I’ve rebooted my core which is a desktop PC, router and Node still has pops and clicks.
Everything is hardwired.
Any other suggestions?
I am also also experiencing this issue.
Here’s my setup:
Roon MacBook Pro (M1)
Bluesound Node (N130)
(USB out to) RME ADI-2 DAC FS
After reading the comments, I got in touch with Bluesound support and they sent me a link to this page.
The problem persists.
Looks like I won’t be continuing with my Roon subscription, which is a shame.
Other than this issue, it’s a fantastic product.
Hi @Kenji_Hayashi, The USB issue appears to be a Bluesound problem? Should your enjoyment of Roon pay? Since BluOS doesn’t do DSD or high Rez above 192/24, try Spdif output. I was very happy with the performance.
Thanks for your suggestion, @RTaylor3rd!
Just purchased an optical cable after reading your suggestion.
Will follow up after I try it out!
Is this USB issue something that’s widely known?
For what it’s worth, I haven’t had any issues playing music streamed from Qobuz through BluOS with my setup (USB out from Bluesound Node to RME ADI-2 DAC FS). It’s just that I don’t enjoy BluOS’ interface.
Thanks again.
Hi @Kenji_Hayashi,
It is widely known. Please do let us know how things go with your optical cable bypass!

same boat here, Roon Core on desktop pc win11, Node 130, remote on ipad, Denafrips Pontus 2 r2r dac. Through coax everything is fine but usb is totally worthless.
Follow-up to my earlier post: I switched from USB to Digital Coax (changed my mind about optical) and no more popping noise! Thank you for your suggestions, @RTaylor3rd and @Wes !
Looks like I’ll be purchasing a 12-mos subscription of Roon after all
