Hi there. Frustrating experience. Tried Roon briefly in 2015, it was a work in progress at the time so I cancelled my membership and didn’t look back. Now, after all the positive reviews, I decided to give it another try and, because I was in a generous mood, I paid for a life membership plus Tidal for 6 months to get the full experience.
I set up my core on a QNAP TS-453 Mini and pointed it at one (!) album out of my several hundreds for testing. I have a late 2012 iMac QUAD i7 with 32Gb of RAM running 10.13.1, some Sony CAS-1 USB desktop speakers, a NAD M17 with the BlueOS module installed and other various bits and pieces but this is my system for testing. My toys are hardwired with CAT7 cables to a 300 series Cisco switch and the routing is done by a Draytek 2862AC.
The testing went well. The Tidal app worked, the BlueOS app worked, the Roon app worked and recognised the mac as well as the USB card (Sony) and M17 and could stream music without issues to any and all.
I didn’t play much because I was prompted to upgrade to the mighty 1.3 and this was the end of it. I can still open Roon and it sees my QNAP core, the Mac and M17 are listed, the Tidal content is visible. But if I try to refresh the Audio devices to discover my Sony USB, it just spins endlessly. If I try to play some content, no audio is sent to either the Mac or M17. The progress bar is frozen, nothing happens. The Tidal app still works well, as does the BlueOS app.
Checking the processor usage I see that Roon uses some 35% of my CPU to do nothing. So I suspect there is some sort of incompatibility with stuff on my computer.
I tried to look for similar problems on your forum but on several occasions I was redirected to a “you don’t have access to this thread” page while a bot messaged me prompting me to become a familiar presence on the forum to gain full access.
With no disrespect to the good, enthusiastic folks on this forum I have no time for forums or socialising and the only reason why I am here is because my 400£ investment is presently useless. For someone who paid a life membership I would expect at the very least full access to your forum, no questions asked.
