Roon has bombed out on me & won't restart

Snowdog · December 1, 2021, 11:55am

Roon Core Machine

Apple MacBook Pro (15" 2017)
Cataline 10.15.7
3.1 GHz Quad-Core Intel Core i7
16GB 2133 MHz LPDDR3

Networking Gear & Setup Details

Virgin Media Hub 3 connected to laptop via ethernet.

Connected Audio Devices

Raspberry Pi 4b with Allo BOSS DAC connected to router via ethernet & to analogue amp via standard phono.

Number of Tracks in Library

Right now, just over 3,000.

Description of Issue

I was editing an album to ignore… Not sure exactly the term, track grouping or something, and the app bombed out. Now it won’t restart. Every time I click on the app it starts to load then just disappears. I’ve restarted the mac, disconnected & reconnected the hard drive that contains the music. When I try to launch the app, it shows the start up logo animation, shows my library for a moment & then disappears again.

When I try to launch the app on my phone I see this:

Firewall on the Mac is off. I use Little Snitch but that is set to allow all Roon connections…

I’m not sure what else to try.

Snowdog · December 1, 2021, 12:05pm

Solved. Re-started the Pi & that seemed to fix it. Sorry, just getting used to all this.

Michael_Harris · December 1, 2021, 12:06pm

Good news that a restart fixed it. It’s a recurring theme in software

Snowdog · December 1, 2021, 12:07pm

Actually, I think I spoke too soon. It did start… Stayed there while I wrote my reply, and then bombed out again, just to embarrass me further!

What else can I try, do you think?

BlackJack · December 1, 2021, 12:10pm

Have look into the log file. If you use the all-in-one Roon installation on your MBP then it is expected that you can’t connect from your phone when Roon doesn’t run on the MBP (nothing to connect to).

Michael_Harris · December 1, 2021, 12:12pm

Is it crashing out while editing again?
Or just starting and crashing?

Snowdog · December 1, 2021, 12:13pm

Just starting & crashing.

Michael_Harris · December 1, 2021, 12:15pm

Ok what @BlackJack says makes total sense. Have a look at the logs.
Have you only recently added the music folder?
You might have corrupted filenames or Metadata causing it to crash

Snowdog · December 1, 2021, 12:18pm

Yes, I’m about 2 days old in Roon Years.

Here are the logs, as instructed:

Snowdog · December 1, 2021, 12:23pm

The thing I was specifically doing, even though I can’t remember the exact wording…

I was playing a soundtrack.

I’ve noticed that in some cases, the first track is almost like a heading & all the tracks below it are indented, almost like track one is a folder or some kind of group node.

I went in to edit the album & clicked on what I think may have been the very last entry in the editing options & clicked on a “no entry” symbol to disable some kind of grouping or something.

This seemed to cause it to bomb but of course, I don’t know if that was a coincidence. I have spent the morning going through adding release dates to the Genesis & Peter Gabriel albums in order to solve the other things I’ve been posting about, so I’ve been giving it lots of new data.

That zone is maybe unstable on your network?

That also points at that specific zone.

Can’t tell you more from the error in the log. Maybe official @support is able to read more out of it.

Snowdog · December 1, 2021, 12:45pm

Thanks. I’ve restarted my router but that didn’t help. Fingers crossed The Support team may be able to shed more light.

Michael_Harris · December 1, 2021, 12:48pm

Del I’m standing in a queue to check in for a flight.
Based on what Blackjack said, try turning off your endpoints and restart Roon

It seems a little suspect if you were editing a file, maybe if that doesn’t work try moving the album to a different folder and see if that does anything. Roon doesn’t touch the file, but anything is possible

Snowdog · December 1, 2021, 12:56pm

Okay, I seem to have sorted it. Roon launched fine with the Pi unplugged & when I restarted the Pi after that, it seemed to be fine.

Thanks for all the help, both of you.

Have a good flight, Michael.

Snowdog · December 1, 2021, 1:04pm

So, having given that the thumbs up, I found that it played fine through my laptop speakers but bombed out again as soon as I switched back to the Pi.

I found the “offending” album & this is the setting I was referring to…

As soon as I switched it back to the Roon default, it all started working again!

So, it now looks like this in the main window…

What the heck is that all about?

BlackJack · December 1, 2021, 1:14pm

Maybe clear the Queue for the failing zone, make the change and then re-queue the album again?

As you can read in the editor window, its about multi-part composition grouping (when files for example contain WORK , PART and/or SECTION tags or such information is retrieved from Roon’s meatdata cloud).

Snowdog · December 1, 2021, 1:27pm

Thanks. Yes, I get that & I’m looking forward to getting deep into it with all my classical music. However, this is a soundtrack album with no multi-part works in it, so I’m just wondering exactly what file tags Roon is seeing to get that information.

I think I’ve learned not to try & change it while it’s playing! I shall investigate further. Thanks again.

BlackJack · December 1, 2021, 1:35pm

File tags are listed above. For unidentified albums information may be retrieved from track titles also. But the main source is Roon’s metadata cloud.

Snowdog · December 1, 2021, 1:53pm

The thing is, when I look at this album using my tag editing software with every available tag column switched on, they are all blank except for the stuff I’ve put in there, so Roon is finding this information from somewhere else & adding it in. It’s fine, though. I’ve switched it off on this occasion & I’m sure it will be useful for other things further down the line.

The next thing is figuring out how to get Roon to display my soundtracks how I like them displayed.
