Same problem here:
Core Machine (Operating system/System info/Roon build number)
Roon Nucleus (Roon Server Software Version 1.8; build 790)
Operating System: Version 1.0 build 227
Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Fritz!Box 7590 router (2 months old) on glass fibre WAN with 300 Mbit/s (this value is achieved regularly, verifiable by speed test). Nucleus connected to Fritz!Box 7590 by short ethernet cable. All connections between router and audio gear by ethernet cable CAT6 or higher. No switches in signal path. Only one SOtM CAT 6 filter.
Fixed IP addresses for both NUC and Amethyst.
2 other network branches and 2 switches have already been removed for test purposes.
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
Roon Nucleus and Trinnov Amethyst (Serial Number 309, Version 4.2.5.1+, RAAT SDK Version 1.1.21) connected by ethernet cable. Preconfigured Roon input on Trinnov. Max. possible buffer size in Amethyst configured (4096 samples).
Build in SSD in NUC.
Qobuz Studio Premier HighRes streaming up to 24 bit / 192 kHz as primary source.
Description Of Issue
Since January or February 2021 I have the following problem: If I stream highres files with 24 bit / 192 kHz from Qobuz via the NUC, the playback stops after a while (between 10 minutes and 1.5 hours). The Roon Server software on the Nucleus crashes and restarts. This also occurs when there is no further network traffic in the house (at night or when nobody is in the house).
The RAAT server also stops and restarts.
The problem does not arise
- When playing highres files from the SSD built into the Nucleus
- When playing back files in CD quality from Qobuz
Highres files with 24 bit 192 kHz require a theoretical bandwidth of 24 bit x 192,000 1/s x 2 = 9,216,000 bit/s. Even if double the data rate were required due to a communication overhead (i.e. 18,432,000 bit/s), then just approx. 6% of the existing WAN bandwidth is used.
I already tried the following:
- Reinstall Operating System on Nucleus
- Shutdown NUC and unplug mains
Does anyone have any idea why the Roon server crashes in the NUC?
