@Carl, thank you for making this a separate issue.
Here is my setup:
Roon Core 1.7 (610) runs on my iMac (4 GHz Quad-Core i7 / 32 GB RAM / 2 TB Fusion Drive with MacOS Catalina 10.15.7)
- Connected via Fritz!Box 7560 router to my Synology DS218+ NAS (both connections via LAN cable)
Audirvana 3.5.41 also runs on my iMac
- Settings > Storage > \myNAS\Music > “Connected – watching for new files in real time”
- I do not scan my local music folder, only the NAS
- Automatic rescan interval: 1 hour
- Initial scan complete
- Settings > Library > Watched folders > /Volumes/myNAS/Music > Auto sync
My issue in detail:
I use the Roon Core on my iMac, and the Roon Apps on my MacBook and iPad for listening to the music stored on my NAS. The effect is the same on all 3 devices (no wonder, as it is the Core that scans the library).
I add a new music folder to \myNAS\Music by first ripping a CD to my iMac (or downloading files from Qobuz), then copying it to the NAS folder.
Then I wait 5 seconds and use the full-text search in Roon to look for the new tracks – not found. Then I use the full-text search in Audirvana to look for the new tracks – and they are all correctly listed.
45 minutes later it is still not showing up in Roon. At some point, the 1-hour scan interval kicks in and it finally recognises the album. But this is a far cry from “watching for new files in real time”.
(The same effect happens for metadata updates, and for deletions: Roon still lists the deleted files, and when you try to play one of them issues a warning that “the track failed to load”, but the album is still shown. After ca. 20 minutes, Roon removed the album and showed a notification “Album deleted” – that probably was a result of the 1-hour interval scan.)
While this might not be too much of an issue in regular listening situations, it is quite annoying at times when I am doing maintenance work (updating metadata on 10+ albums, ripping CDs etc.). Audirvana does not have a problem at all at spotting those changes in real time – so it is not a NAS problem.
Is there a solution to make Roon more responsive?
