iMac Core updated to 1.7 Experiencing Skipping

I, too, am experiencing this issue since 1.7 update. Streaming Qobuz tracks randomly skip to next track when playing on 2 different endpoints from Roon Core on sonicTransporter-AP connected directly to Orbi router: 1) iMac (10.15.1) to Schitt Modi 3 USB DAC; 2) Sonore ultraRendu to Mytek Brooklyn USB DAC. Both endpoints connected to network via CAT 6. No DSP.

Hi @wkimbel87

Sorry to hear that you’re experiencing this behavior, can I please request the following information so that we can better understand the issue?

  1. How often are you seeing this behavior? Is it once an hour, once a day, more/less? Does it seem to happen with specific content? What was the exact time this last happened?
  2. What are the specifications on your iMac Roon Core (CPU/RAM)?
  3. What is your internet connection download/upload speed? You can check this on speedtest.net
  4. What is the exact failure state - Does Roon fail to complete the song mid-way? Does this issue ever occur at the start of the track?
  5. Does logging in and out of Qobuz/TIDAL have any effect?

Once again apologies for the frustrations here, please let me know the above details when possible for our investigation. Thank you.

Hi @nathan2.
Please note that my core is not on the iMac. As noted, it is on a SGC sonicTransporter-AP, where it has been for several years now.

I see this behavior on 1 or 2 tracks on each album I stream from Qobuz, and not (so far) on the same tracks when I play them again.

Typically it occurs more than half-way through the track (skipping to the next track).

I’ve got plenty of bandwidth (170 mbps download; 22 mbps upload).

I have logged out and back in into Qobuz but have not had a chance to check whether this makes a difference or not. I will report to you soon.

@nathan2 - Logged in and out of Qobuz but the skipping reoccurred after playing a whole album plus random tracks from different albums without any problem. On repeat play, the track did not skip a second time but played through to end and then on to next track. It seems to be a very random, occasional but persistent issue.

Here is what Roon Server Log shows:

Thanks for the update, @wkimbel87!

As a test, can you try lowering the quality of Qobuz in Roon temporarily? Is there any change when doing so?

@dylan–After limiting Qobuz to 16/44, I streamed several albums over about 90 minutes without any skipping.

NB. This was in Build 500. Now with Build 505 installed, we’ll see…
