No worries at all, I just replied right above you at the same time. I still tested anyway and still get pops with the SMPS powering the Rendu.
NAA is version 3.5.3 also.
Colour of wallpaper perhaps?
This is akin to voodoo !

Ha. Are you able to see loading of each individual core on your machine? I saw earlier, that overall usage is low when youāre getting pops, but what about individual cores?
Is this the sort of thing you mean?
This is playing Crisalide with poly-sinc-short. (No pops -at the moment).

Yep something like that.
Well arenāt you lucky! I donāt want to jinx you.
Well, thatās sorted my listening before I head off to work

You have quite heavy filter selected for high DSD rates, so itāll need fast machine. The delay between tracks happen if the sampling rate changes from track to another, HQPlayer needs to reinitialize the DSP pipeline for new input rate, especially in the case in your screenshots, where output rate is 44.1k-base and input rate is 48k-base. That will take time with those filters. Some clicking between the tracks in that case is possible because the DSD stream restarts and mutes the DAC for a moment (depending on particular DAC, but in your case it is Oppo, so ESS Sabre which will auto-mute in this case). This is completely different case from any clicking during a track playback.
Good explanation thank you.
My processor speed in Roon is typically at 1.8x so that shouldnāt be an issue.
I donāt know what that is, but it has nothing to do with HQPlayerā¦
I believe it has to do with How well the host computer handles all the calcs associated with whatever dsd is in the chain eg hqp.
Hi George, I think Jussi means since that āprocessing rateā applies only to Roon up-sampling, it doesnāt have anything to do with HQPlayer.
In your screenshot there, that is Roon doing the DSD up-sampling, not HQplayer.
Aha , user error? If Iām using HQPlayer to do the upsampling do I disable the sample rate conversion in the Roon DSP module?
Thankks,
George
Hi George, yes thatās correct. You definitely donāt want both Roon AND HQPlayer doing up-sampling at the same time.
Donāt worry about user error - weāre all always learning in this fun hobby.

So, removing the redundant upsamping in Roon, along with limiting the bit rate in HQP to the max that my dac will accept, seems to have done well for the sound. Quick listen of Bill Evans had no clicks. Hereās hoping it solved the issue long term.

Great news George. Just a refresher, which DAC do you have again and what are you up-sampling to with HQP? And which filter? Can you provide a screenshot of your HQP settings, probably easier than typing it all out.
I was a little confused by an earlier comment āI actually prefer the higher setting of dsd 512,(at least in Roon playing HQP) even though my Dac doesnāt support more than 256.ā
Iām trying to follow everyoneās system here, that has had pops.
Cheers in advance.
George is using an Oppo 205.
There are multiple sufficient causes for pops. I think Georgeās resulted from double upsampling and feeding his DAC a higher resolution signal than itās spec.
@jussi_laako has been able to reproduce the issue at his end, with pops at DSD512 with his microRendu NAAā¦
Heās in discussions with @agillis .
Both of those guys are very very clever and nice guys and Iām confident they will figure it out.

Well thatās good news, do you know this from personal correspondence or is there a thread elsewhere?

Offline emails with them this past week.
I was pulling my hair out, especially in my other thread, but now can relax as they work to fix it. Iām confident those smart chaps will sort it out.
Their customer service is first class.
