Sonore microRendu

[craighartley]

I have previously been using a Windows naa to feed audio streamed over my network by HQPlayer. I’ve just tried replacing the naa pc with the MicroRendu (updated to 2.7), and I get a regular tick through my loudspeakers every 9 seconds, whether music is playing or not. Any ideas why?

 

If I switch the MicroRendu so that audio is being streamed direct from Roon, the ticking remains exactly the same. 

 

As soon as I replace the MicroRendu with a mini pc using Miska’s bootable naa image, the ticking disappears. 

 

The MicroRendu is powered by an Ultracap LPS-1. The network connection is by cat 6 Ethernet to a fibre optic adaptor (night this be the problem?). A usb cable goes straight from the MicroRendu to a T&A DAC8 DSD. This is the same setup that works fine from the mini pc with Miska’s bootable naa image. 

 

I was hoping the MicroRendu would simplify things, and that I might go on to invest in one of its more sophisticated siblings, but this is a bit offputting.

 

Thanks to to anyone who can help.

What happens if you use the LPS-1's charger to directly power the Rendu?

Thank you! 'Charger' was 12v linear power supply, which I didn't want to plug directly into the Rendu; replacing supply with a 9v lps eradicates the clicks.
