Description of Issue

Bumping this for visibility. This exact issue has been happening to me for the past few weeks as well. A few times/day music will stop, I’ll receive the same progression of messages as the OP, and will be asked to select a different core. 50% of the time I can select the same core (and it says it’s available) and life continues until the next round of "uh oh"s, the other 50% I have to restart the core.

I’ve seen this issue on both of my cores, one on a Synology and one on a MBP, so it’s not isolated to any one platform.

Best I can tell it started happening with the last update to 970. I just upgraded to the latest release today, 987, and will share if the issue goes away.

I just tracked down the cause of this in my environment: I was running two cores as I was migrating from one core (NAS) to a new core (MacBookPro). I wasn’t trying to use two cores at once, and only one was Authorized, but I had both running as I was bouncing back and forth for backups and restores. It wasn’t 100% repeatable – sometimes the playing core would stay up and play for days, sometimes it would “Uh oh” every track. I was able to track it down during one of the “Uh ohs” per track by looking at the logs and seeing two things:

  1. Chromecast endpoints were constantly going up and down. I was seeing this in the UI (Settings → Audio) as they would be listed as available for a few seconds, then go away, then come back, etc. The log entries looked like this:

  1. I caught the following in the logs of my MBP core, which I thought was odd b/c the Synology isn’t doing anything except running a core.

I shut down the core on the NAS and the MBP core has been playing solid for a few hours w/o issue.

As long as the Roon binaries are running, you can look at the logs to get the version. It’s not ideal, and I didn’t see a way to ask the actual binary for a version, but this works:

% grep -i "_version" ~/Library/RoonServer/Logs/RoonServer_log.txt | head
07/12 15:01:12 Trace: [roonapi] [apiclient] COMPLETE Success {"core_id":"<UID>","display_name":"RoonMac","display_version":"1.8 (build 988) stable"}

100% agree. I estimate that I spend ~4 hours per week fighting with Roon to either fix issues, ask for support on the forums, doing my own troubleshooting, etc, which is literally insane for a piece of software that I pay for. Imagine if you had to spend 4 hours per week keeping Netflix up and running? No one would stand for that, no idea why the Roon community tolerates it.

Before 1.8, Roon was amazing. Since 1.8, Roon has been so unstable it’s basically become unusable, which is crazy sad b/c they basically own this market.

I renew in about 10 months and will be spending that 10 months looking for an alternative that supports streaming to the endpoints I invested in before 1.8. If I’m going to spend this much time on keeping music streaming up and running I’d prefer to use OSS software where I know what I’m getting and/or have the ability to fix things for the broader community rather than my own env.
