Description of Issue
Intermittently, my DAC seems to lose connection to my Sonore UltraRendu. Music stops playing. Some combination of restarting the DAC and UltraRendu, sometimes multiple times fixes it. But, the problem comes back.
RoonServer logs while it was happening below.
It seems fairly obvious that either a connection was lost between the core and the UltraRendu, or the USB connection to the DAC was lost. I am trying to narrow down where the problem is in my chain, because itâs becoming quite annoying. I will be happily enjoying an album and boomâŚtotally kills the mood.
Thanks, but the device already gets a DHCP reserved IP that is never used by another device. Also, when it happens, the UltraRendu is pingable, so I donât think it is an IP reachability issue.
I would also consider trying a different USB cable. If youâre using an âaudiophileâ cable, try swapping it out with a bog-standard normal USB cable.
I had something similar a while back between an ultraRendu and a Chord TT2. It turned out to be the LPS 1.2 powering the uRendu. I swapped in a Farad I had in my âlibraryâ of spares.
I was losing my endpoint sporadically. First I did the normal troubleshooting:
Rebooting Core
Power cycling the TT2, ultraRendu, LPS1.2, and switch
Replacing the USB cable from the uRendu to the TT2
Changing ports on switch
Replacing Ethernet cable from switch to uRendu
Then I moved the uRendu to another system that also had a uRendu and the problem did not move⌠The second system also had a LPS 1.2. I moved the original LPS 1.2 to the second location and within 3 hours or so, the problems started to occur.
Ben with the support team here, itâs great to see you on the community again! Iâm sorry to hear youâre having issues with your endpoints disconnecting. Since a few days have passed, I wanted to check in and see if you were still running into this issue?
And in the meantime, I always suggest temporarily removing any switches from your setup chain as a test.
Hey Ben, I unhooked the UltraRendu and LPS 1.2, then reseated all the cables and positioned them back facing me so I can monitor the LEDs.
I have still had to do the DAC dance where I power cycle the DAC and UltraRendu to get everything initially running sometimes, but no mid session dropouts yet since the move.
I have had an album looping in Roon for days with no dropouts. But, I have been here before, and it seems to crop up eventually. I am continuing to do testing and will report back if something changes.
