USB out

Answered

Hi,

I'm using the latest Bluesound Node updated with the lates firmware. I've been trying to use USB out to my dac, but I hear intermittent crackling noise and momentary dropouts. I don't know if this is only me or usb out on Node needs further improvement. I'll be fine with the latter, but I need a solution if the former is the case. I'm currently using coaxial out to my dac, and it works flawlessly. I would still like to try USB out particularly for its ability to play DSD files.

  its been two months and still no answer, i've got almost same problem as Keewoong, but my crackling noise can be heard when i am listening mqa for tidal, with dragonfly cobalt. Any news regading this issue? when i'm using built in dac, everthing is working just fine.

  Dear Sveto,

  It turned out that my problem happens only when I use Roon through Bluesound Node's usb out to my dac. I've been using Tida Connect and Bluesound app on the same system and there was no problem. The Roon problem seems to be widely known as Alvin from Vinshine audio also mentioned it. Please see https://youtu.be/15VrAQT8gA8. In this video, Alvin recommends to disable "audio clock stream" in Bluesound app settings. I would also like to suggest your mqa setting to "renderer only". Hopefully, this could sort out your problem.

  I am using only blueos app on my Phone, and the problém is that dragonfly is switching between mqa and other formats all the time. I might try another Dac and I will connect it with digital coax. When dragonfly work, sound is so much better, it’s a shame :(
