An audio file is loading slowly - usb connection

Here are the screenshots. As you can see Roon is the only process who is taking most of CPU. While it is still showing that is running but signal/audio is not coming out anymore.

Hi @Ashkan_Gholamzadeh,

Thank you for sharing those screenshots! John flagged us down regarding your case and we have been discussing it with our QA team today, I have some further feedback for you here:

  1. Can you please provide a sample of the Roon process when you are in this state and unable to paly to your McIntosh zone? If you open activity monitor, you can right-click on the Roon process, further instructions on how to do this can be found here.

  2. How long do you usually leave the Roon app running for? Does this issue only occur after the Roon app has been running for a certain amount of time? If you exit out of Roon and open it again, are you able to reproduce the issue within a few hours of a new session?

Please let us know when you have a chance, thanks!

Here is the sample. I can copy the full sample file because of size limit on body. Also I can’t attach a txt file. The issue happens when roon app is running for a certain amount of time. It’s vary from 2 hours to 5-6 hours. Usually I need to reboot computer to get it work and then the issue can happen if I leave it to run for a while.

Hi @Ashkan_Gholamzadeh,

Thanks for providing that snippet of the sample process.

It has been a while since we spoke, have you also updated to the newest Roon build (610) and can confirm the issue still exists there?

I can get the sample process over to QA, but they also had one other question - can you check to see if you are able to reproduce this behavior when using a RoonServer type of Core?

You would need to download RoonServer from our Downloads Page and then have the existing Roon app connect to the RoonServer instance by going to Roon Settings -> General -> Disconnect.

RoonServer is a Roon Core with no interface and needs to be controlled by remotes. It would be good to know if RoonServer exhibits this issue as well.
