Core Machine (Operating system/System info/Roon build number)
Intel Nuc Kit NUC8i3BEH with 128GB SSD. Running ROCK; OS Version 1 Build 227; Software Version 1.7 Build 667.
Network
On ethernet is ROCK; Melco N1A Music Server; Bricasti M5. All direct connected to the modem/router. ROCK has only one foot of cable between it and the router. The server is connected via 10 Meters of CAT 5; the M5 is connected via 10 Meters of optical cable. Other routers, switches not used and powered down. Remote is Macbook operating via Wi-Fi.
Audio
Audio is via Bricasti M5 feeding a Denafrips Terminator DAC.
Description Of Issue
There is more than one issue, although they may be related. Also its important to note that I have had Roon for several months. I have been using in conjunction with a Sound Pro speaker and also with Chromecast audio playing thru my Denafrips DAC and main system. Roon and my network have performed without problem before the introduction of the Bricasti M5.
First issue is that M5 can only be seen on network, or by Roon if it is connected directly to the Router/Modem. I usually have all of my audio system on a Cisco 2960 switch. In order to get the M5 to be discovered, it had to be direct connected to the router/modem.
Second issue is only the M5’s SPDIF output (and not the AES or USB outlets) output signal. There is one strange exception to this. In troubleshooting I discovered that those outlets will output signal if the unit is cycled off and then on again. [I am aware the M5 requires rebooting to switch from AES/SPDIF to USB. This is not the issue.] However the M5 will only render the first music file. When Roon advances to another file signal is interrupted. At least some of the time I can go back to that first file and can play it again. Not sure if it is consistent, but at least often, when it will not output signal, the AES will output a multiple echo of a passage of the music. When it will not output signal, the USB will often produce clicking noises. I believe this shows that these outputs on the M5 are functioning and that they interface with the DAC OK. It is as if the M5 cannot follow commands coming from ROCK or, perhaps the M5’s outlet switching function I mentioned above is malfunctioning.
I have reloaded the Roon OS; reloaded CODECS (only the single exec file, nothing else–is this correct?); moved the M5 off CAT5e and onto optical; moved Melco server to different ethernet outlet; moved all devices off switch and direct onto modem/router; removed all DSP processing in Roon; rebooted everything numerous times. Nothing seems to work.
Third issue is that sometimes, when music is playing on the SPDIF output, a change to another music file will result in loud static overlaid onto a low volume music signal. At that point Roon cannot control the output. It requires shutting down Roon on the remote and then re-loading it, sometimes more than once.
