Description of Issue

I have multiple DACs for different rooms around the house, (Cayin, BluSound) and the Michi P5. All the other DACs work without issue. The Michi however, makes a popping sound between songs almost always. I have tried almost every combination of settings and can not get rid of the problem.

I just got the email (you know the Roon Mastery series) It mentions changing the resync setting. I went to the max and it did not resolve the problem.

3

I would appreciate some sort of response to the post I created

4

Is this occurrence when it’s a change of track resolution?

5

Try using a different USB cable, and different USB sockets on the Mac Mini.

6

Yes. It happens when changing tracks.

7

I did change the cable but haven’t tried a different usb port. I was also going to try a USB C to USB B

8

Every time? Or when bit depth or sample rate changes, e.g., 44.1 kHZ to 192 kHz?

10

It seems to happen all the time. However, I will need to look at the signal path from song to song to be sure. And I assume you mean the source levels, correct?

11

Not really.
What I meant by track resolution is the bit rate.
So say if one track is 16/44 then the pop occurs and next track is say 24/96 etc.
You will need to look at signal path for this

OK… the source format changes always seem to cause a problem… here is a sequence where there was a pop between song 1 and 2, then none between 2 and 3.

Here are more images… these are device settings for the Michi

This sounds unfortunately like a DAC resolution switching problem, not Roon…
You might need to contact the DAC manufacturer.

15

Question. Why is this set for dsp volume. Are you not controlling the volume at the integrated and not with the roon controller.

16

10 seconds Resync Delay, really? Is so much necessary? Maybe the DAC switches the input off and then on again which causes the pops?

17

I control the michi from a separate room.

18

I’ve tried every option on the list. There was an email from Roon recently that recognizes this problem and they suggest to increase the resync.

19

This would be very unfortunate. The P5 is supposed to be “high end”. I just did a firmware upgrade too. You got me thinking though… My S5 went back to the factory for repair. Maybe these Michi units aren’t want they’re hyped to be. Although when they work they do sound pretty amazing.

20

One other thing. This is my only DAC that is connected directly to my Mac Mini Core machine? Could the Mac be causing a problem? Also the only way to get the highest resoulotion out of the Michi is to use the USB-B connection. Specs:
Digital Inputs SPDIF LPCM
(up to 192kHz 24 bit)
PC-USB USB Audio Class 1.0
(up to 96kHz 24 bit)
USB Audio Class 2.0
(up to 384kHz 32bit)

Just bought another newer cable and switched ports on the Mac and the problem persists.
