I tried, but no crash for me. (1244 core on m1 mini with 13.3.0 and remote on a 14,3 iMac 10.15.7 os)

[ucchi]

P.S.
I have 26 MQA-CD albums in Roon library, with (MQA) as the album title.

[Traian_Boldea]

Oh, for me all are on tidal (added to library), dunno if any has (MQA) in the title

[ffk (Doctors Practice. Plumbers Perform.)]

Traian, your using focus, OP is using filter.

@ucchi

What if you filter just ( , does it crash?

Does focus on MQA work?
Now that I think about it, That probably work as it’s a MQA CD.

Does it have MQA encoding?

[Traian_Boldea]

Ups… thank you @ffk
But still not crashing

[ucchi]

thank you @ffk
No crash when filtered by (.
But it crashes when filtered by (M.
It also crashes when using Focus (OTHERS - MQA).
Albums are MQA encoded.

[Traian_Boldea]

(MQA MASTER) - not crashing

tried to copy paste (OTHERS - MQA) - not crashing

I would love to crash it but no luck. tried: MQA, (MQA), (M., etc

[ucchi]

thanks for the test @Traian_Boldea
A) MQA encoding albums in Roon library.
B) The album name contains (MQA).
It seems to crash when A or (A & B).

Hi @ucchi,

Thank you for your patience. The team has pulled diagnostics from Roon on the affected device and noticed two issues:

1. There were log traces indicating failures in Roon to load local content due to Time Machine activity on Watched Folders. Are you using Time Machine on your local library on this iMac as an alternate Roon library backup mechanism, by chance? If so, we recommend disabling Time Machine on any Watched Folders, as it often prevents Roon from accessing the drive.

2. The UI component of the app is responsible for crashing on Mac per the logs, but I suspect the underlying failure is related to local storage mounting of the drives containing the MQA content. However, just to dig further: do you get any crashing when you attempt to load any of these albums outside of the Browser? For instance, by searching for a track directly and then clicking on the version in your Library?

We’ll keep an eye out for your response. Thank you!

Hi @connor

1. TimeMachine
   The Roon libraries are located on the internal Storage of the Nucleus server.The folder is set as “Nucleus Internal Storage”.
   MQA CDs are ripped by XLD and then added to iTunes library. The file format is ALAC.
   I manually copy the ALAC files from my iTunes library to Nucleus Storage.The Nucleus Storage is smb mounted on a Mac to do this work. The folder is mounted on the Mac, but is excluded from TimeMachine.

2. MQA Content
   MQA files (ALAC) are registered in the iTunes library and can all be played. I can also view their properties.

3. Search function is available.
   The filter function for Search results also works.But when I filter with MQA in My Albums, Roon crashes.
   

   
   
   
   
   
   
   

Thanks.

MQA files (ALAC) are registered in the iTunes library and can all be played. I can also view their properties.

Not sure I’d matter, mqa can also be ripped to flac as long as the compression level is set to default. If you change compression setting it will damage the mqa signal. Still don’t think I’d matter though.

Hi, @connor
This issue was fixed in Roon 2.0 (build 1259).
Thanks.
