I have a similar but possibly separate issue. I have a PS Audio PerfectWave II DAC connected to a Parasound Halo AC21 Amp. I have a Mac Mini connected directly to the DAC via USB, running Roon, which I use in client/server mode (the Mac Mini is the server, my Mac laptop is the client that I use to choose the music). The DAC is set to run at “native” sample rate. When using Roon, if I manually switch between songs (i.e., I start playing a song, find a new song, then start playing it instead), there is a “click” noise that comes from my DAC. If I change the sample rate to “nativeX” there is both a “click” and a short moment of static from the speakers. After that the song starts and sounds great. None of this occurs if I play an album and simply allow the songs to progress normally from one to the next. If it matters, I generally operate in Core Audio Exclusive Mode, although switching to other modes does not change this phenomenon. I also check the “Use Integer Mode If Supported” box but, again, unchecking it does not fix this issue. This is a PCM DAC (no DSD).
When I perform the same tests on the same setup in Tidal or iTunes, there is no clicking noise. I can literally start a song in Tidal, switch to a new song, and not hear the click, whereas if I do exactly the same test in Roon, with the same songs, I hear a click. Any thoughts on how to make the noise go away? I doubt it’s the case but I’m afraid I’m damaging something.
Thank you,
Ben
PS - I love the Roon product and am so grateful for all the thought and effort you’ve put into creating it and supporting it. Thank you so much for creating this excellent and excellent sounding mechanism for managing music and remotely controlling music servers.
