Hi Dylan, thanks for you help.
It worked. First, I had to unplug the network cable.
Then I could disable all connected folders.
Roon then started accurate.
I connected the folders again and it worked.
But I still do have huge problems with my playlists.
My Music folders are scanned automatically every 24 hours.
But then roon first deletes all links to tracks in one folder (my HD Musik). I can see the amount of tracks and albums counting down.
After deleting all tracks/links from one folder (the files are not touched) Roon starts to reconnect all the links to the files. After that all files/links are back.
But my playlists now show “not available” to almost any of this tracks.
That’s VERY uncomfortable for me, because I have a lot of playlist with a lot of included tracks.
Only a backup helps (which is uncomfortable and took a lot of time).
What can I do?
The System crashed again.
Roon did not react anymore so I tried to close Roon.
But this did not work so I had to restart my MAC (on which Roon is running).
Please check on my playlist problem.
It happened again today.
Out of nothing Roon starts (around 10 a.m.) to re-scan one folder (my HD Music).
First you can see that all tracks are counted down und then all are counted up again.
So at the end I still do have all my albums and track numbers.
But a random amount of links in my several playlist are marked “not available”.
What can I do? Please help
