Core Machine (Operating system/System info/Roon build number)
Roon ROCK with all the latest (as of August 28, 2020) Roon-recommended ROCK components: The Intel NUC10i3FNH along with the recommended RAM and SSD.
Roon Version - 1.7 (build 610) stable RoonOS Version - 1.0 (build 227) stable IP Address - 192.168.1.251 OS Version - Firmware 1.0 (build 227) stable. My Roon Remote is an iPad Pro 10.5 running iOS 13.6.1. The Roon Remote is version 1.7.00610.
Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Synology RT2600AC on the latest firmware, Ethernet hardwired into the ROCK. The Internet connection is a symmetrical fiber 500Mbps download/upload.
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
The ROCK is connected via USB to a FiiO K3 USB DAC, which then is connected via coaxial digital output to an Anthem MRX 720 receiver, which does the D/A conversion. I want the receiver doing the D/A conversion for its Anthem ARC room calibration, bass management, delays, etc.
Description Of Issue
When playing a playlist or the queue, Roon Player cuts off the first one second of each track. It only does this when changing bit depth or sampling frequency. It never does it when going from, for example, one 16-bit/44kHz track to another 16-bit/44kHz track.
This happens every time. Changing the resync delay in Device Setup slightly improves the track cutoff to roughly half a second, whether that delay is 1000ms or the maximum 10,000ms.
The issue manifests with the optical connection as well. It does not manifest when listening to headphones directly from the DAC.
The issue also manifests when using a laptop (in place of the ROCK) running the Roon Core through Windows 10 with the same DAC and receiver.
The issue happens with either Qobuz or Tidal, which is where I’m getting all my high-resolution music. So, that’s where I’m getting the audio resolution changes from track to track. It also doesn’t matter whether I create the playlist in Qobuz or Tidal, or in Roon.
Including both streaming services, there are 28,478 tracks in my library.
I realize that things seem to point toward the digital-to-analog conversion in the Anthem receiver or the receiver’s interaction with the DAC, as the DAC itself doesn’t have this issue when listening through headphones directly from the DAC. However, the DAC performs perfectly with direct playback from Tidal’s app, the Qobuz app, or Audirvana, using the same Windows 10 laptop and Anthem receiver mentioned above. The only app that manifests this problem with the identical setup is Roon.
My question is, can anything be done about this? Thanks so much in advance for any help. And take your time – it’s Labor Day weekend!
