I’m using MacBook Pro (macOS High Sierra 10.13)>Roon v1.3>ultraRendu v1.1.21 w/Sonic Orbiter v2.5 using a KTE Holo Audio Spring DAC and I’m intermittently hearing soft, as well as very loud clicks/pops when initially pressing play and skipping forward/backwards. Also, when switching sample rates or from PCM to DSD (and vise-versa) I’m hearing very loud clicks/pops.
I’m new to Roon as I’ve mentioned before, so any help with this issue would be very much appreciated.
Thank you for the reply and suggestions. Prior to my post I did some research and increased did increase the re-sync, but unfortunately this didn’t solve my issue. I haven’t tried setting the sample/bit rates as you recommended, though. I’ll try doing both at the same time and see if this solves my issue.
Hi @Joseph ---- Touching base with you to see how things were going and if any new progress or observations have been made since your initial report. My apologies for the slow response.
Please let us know how things are holding up and if further assistance is required, drop a flag for “support” (i.e @support) in your response so the team is notified of your feedback, and we’ll be glad to lend a hand.
Ive changed the setting according to Andrews advice, but still had the popping/clicking issues when changing the Resync sample/bit rates, but to less of a degree. I still need to play around with these setting before giving my final results, I just had a busy weekend and haven’t had the time, but I will keep you informed. Thank you for the reply.
I’ve powered my Spring DAC/SU-1 on/off for a good 1/2hr and I’m still getting the clicking noise while changing sample rates. I’ve set my Max Sample Rate (PCM) up to 768kHz (being my DAC/SU-1) supports this) and my Resync Delay is set to 100ms (from 50ms) and the Max Bit Sample is set to 24. Tonight I’m going to increase the Resync Delay to 500ms and report back.
Just a quick thought, would it possibly help if I re-installed Roon? I ask this because I’ve noticed when I swipe to the Roon window from other open windows (e.g. Safari/Mail) with the touch pad on my MacBook Pro I’m getting a quick flash (like a camera flash) from the Roon window which I’m not getting when swiping to any other open windows.
Hi @Joseph ---- Just touching base with you to verify that I have seen your PM update to me, thanks!
Moving forward, I think your idea of testing with the Holo Spring DAC mounted directly to the core machine is a very good next step here. Please let me know the outcome of this test and we can continue narrowing down some variables.
Lastly, did you get a chance to test with music being played out of the internal speakers on the core device?
Previous post: “Confirmed if you experience the same behavior via the system output on the MacBook Pro?”
I haven’t had the chance to continue my process of elimination due to being too busy lately. Tonight I just felt like enjoying some music without testing and launched Roon and was experiencing clicking/popping between tracks on the same album from a Tidal FLAC file 44.1/16 which was the first time this ever occurred.
I quit Roon and re-launched and the issue totally disappeared. Don’t understand what’s going on, very strange behavior. Anyway, I’ll report back on my initial issue with the popping/clicking noise while switching between sample/bit rates when I get the time. For tonight, I just want to enjoy the music.
Tonight when I launched Roon and started listening, there were pops/clicks before and after the tracks playing tracks, so I quit Roon and re-launched and all is good? This is the second time I’ve done this and it has solved this issue. Would you know why this would be? Has anyone ever experienced this same thing?
Yes, I’m sorry, I’ve done the tests with the same results. The only way for this to be solved is by re-launchning Roon, then I don’t have any issues with popping/clicking at the beginning/end of playback, but still have it while switching sample/bitrtes…this I can’t seem to solve even with the re-launch.
It would be nice if your techs have the Holo Spring DAC, I would like to hear about their finding when switching sample/bitrates, as well as why I need to re-launch Roon when I have the popping/clicking issue at the beginning/end of tracks, but after a re-launch, It’s fine?
Thanks for verifying this information for me @Joseph, very appreciated!
So based on your follow up, you experience the clicks/pops via the internal speaker of the core machine as well as with the DAC mounted directly to the unit? I just want to make sure I have all of your observations right before I ask for feedback from our techs.
Lastly, when you have a chance Joseph, can you also provide me with a screenshot of the signal path leaving Roon when you hear these pops/clicks?
I re-tested before replying, this time with different findings.
(1st screen shot)-Output “OS Mixer” initially I had the issue, but then it went away without re-launching?
(2nd screen shot)-Output “CoreAudio Exclusive Mode” I also experienced the same issue, but again, it went away without re-launching?
Also, in “Exclusive Mode” switching sample/bitrates went seamlessly without issue, which by the way, could only be done in “Exclusive Mode” which automatically switches the MBP’s sample/bitrate in the “MIDI Set Up”. Otherwise, in “OS mixer mode” I would need to go into the MIDI Set UP and manually select/match the sample/bitrate.
