Hi, I’ve been using Roon 1.3 for about 1 month as a new customer and I have experienced several issues.
My initial configuration :
Roon 1.3 (build 223) (the last one available at the moment)
Roon Core running on an iMac Retina 27’ 5K 4 Ghz Intel i7 2016 with 32G DDR3 RAM, macOS Sierra 10.12.4
Roon Client : Auralic Mini Firmware 5.0 beta 4 (to be fair Roonready is still in beta and not certified yet)
DAC : Emotiva XMC-1(the Auralic Mini connected to the XMC-1 via USB)
NAS : QNAP 453 Pro, Inter Celeron based, 8 G Ram used only a as network drive
All the networking is based on ethernet cables with the devices connected by cable through a gateway (no wifi)
Audio Collection: 85K tracks, about 6000 albums
The 1st main problem I experienced was linked to the continuous scanning and automatic progressive loss/erasing of albums from the Roon library located on the NAS …
When I say “loss” I mean that after building the full library and having completed the background analysis so with a system apparently “perfect” I have seen that after adding additional albums to the library, after a while but happening regularly I was able to see “live” the counter of the library albums progressively decreasing like if someone would have removed progressively the albums from the library. This countdown was usually stopping at different levels … (for example if the full library was always about 5800 albums when the "mass removal action’ was initiated, once I have seen the mass removal of the albums stopping at a level of about 1000 albums, another time it stopped at about 200 etc…
I found a thread which was describing a similar problem and how this could be linked to the unreliability of OS X in confirming the content of the watched folders…
After the album removal the system gets in a loop where the scanning keeps adding again albums to the library, then something happens and start to remove them again making the system almost useless as it is a constant library scanning…
Disappearing Tracks
We’ve investigated this about half a dozen times over the past year. It’s actually more of a problem with OS X than with Roon (which is why Roon on other platforms does not suffer this symptom), and it is relatively rare, meaning we have many users using network storage on Mac without this symptom, and only a handful who see it. This suggests that it’s in some way correlated with setup details or habits of those users.
Anyway, this was pretty annoying as it made Roon totally useless in my network configuration and I was forced to move all the audio library from the QNAP NAS to a RAID 5 4 disks hard drive directly connected to the Mac which is seen as a local drive.
The library problem is now completely solved in the new configuration but using the system more extensively I see sometimes strange behaviors from Roon when I try to play some albums, sometimes using the DAC sometimes or sometimes even locally on the iMac using the local default zones: (System Output and Apple Core Audio).
I’d like to ask your support for this special case as it is not linked to the network, Roon is actually playing a local file on the iMac from the locally connected RAID drive and no networking is involved.
I have the same album:
’In a a Twist’ from Bria Skonberg
in 2 different versions: MP3 16 BIT 320 Kbps and FLAC 24Bit 96kHz.
The FLAC version which is obviously heavier is reproduced without problem from Roon on the iMac locally using the local system output while the MP3 is sistematically creating a repeating noise during the reproduction and practically blocks Roon until a new zone is selected.
I noticed that when this happen also the Apple Core Audio and System Output zone seems to disappear for a while, then they reappear. But every time the MP3 file is reproduced, it systematically generates the Roon problem.
The same album, located exactly in the same location where Roon has problem to play it, is reproduced perfectly from :
- the OS X through the quick play activated pushing the space bar on the file from the finder
- VLC
- Audirvana
- other players like the Aurora Blue Ray players etc.
This seems to prove that the album files shouldn’t be corrupted as they are reproduced perfectly with the other players…Roon is actually the only one having problem with this MP3 version…
Any possibility to check on your system ?, I could upload both versions for your check…
Thank you
