Windows 10 Pro
8-core Intel i7-7700 CPU @3.60GHz
64 bit system
Motherboard - ASUSTek Strix Z720E Gaming
Sound controller - AudioQuest Dragonfly Enabled, Realtek High Definition Audio Enabled; NVIDIA High Definition Audio Disabled
Roon Core installed on PC
Version 1.7 Build 610
Music Library on USB External HDD, 50K tracks
USB DAC on PC: either AudioQuest Dragonfly or Halide HD USB DAC (one connected to PC at a time)
DAC connected to Aperion Audio Allaire speakers by audio cable (Bluetooth not used)
Windows Defender Firewall defaults to Norton Software. Norton Firewall allows both ROON and RAAT.
When I first started using Roon about a year ago, I had no problems. Over the last 3-4 months (after a Windows update, I believe), I have been experiencing a regular problem where ROON does not see either USB DAC upon boot up. Other programs (VLC, Adobe Audition, Adobe Premier Pro, Audacity) all see the DAC without any issues. Only ROON is having an issue seeing any USB DAC. The problem occurs only when the machine boots up. Once I fiddle and somehow get ROON to see the DAC, it works fine while the PC is up and running. If the PC is rebooted for whatever reason, ROON does not see the DAC. It happens every time I boot up the PC.
When ROON starts up, it would ask to select audio zone. It recognizes both my Aries LE and my Aries Mini on my network, connected wirelessly; but does not see either DAC (Dragonfly or Halide) connected directly on the USB port of the PC. Both DACs work fine in other systems and both DACs work fine once ROON sees them.
I have tried the following when I encounter the problem:
- Plug the DAC into another USB port
- Switch DACs
- Disable Norton Firewall
- Reboot ROON
- Disable and or enable sound controllers on Device Manager, which sees both Realtek and either DAC I use.
- Reboot the PC
I have tried any and all of these in various combinations. Hence “fiddling.” The results are inconsistent. Sometimes one of the above works, sometimes a combination works. There is no clear pattern I can discern.
When I finally get ROON to see the DAC, I sing praises, have a drink, play music and try not to shut down my computer. Needless to say, this is a very annoying issue. There is also the contingent problem where my family cannot boot my the PC and play music if I am not around.
I would dearly appreciate any suggestion which could permanently solve the problem.
Regards and many thanks.
