OK, So I cannot get any playback at DSD512, on any Mac system with any modulator - it plays for a few seconds, then drops out for half a second. Rinse & repeat. This is on a gigabit wired network, and have tried with the following HQP hosts:
M1 Mac Mini 8/256/MacOS 13.3.1. We knew this wouldn’t work, but this machine hosts Roon
the above Roon server feeding HQP5 on:
a) Macbook Pro M1 Max (32GB, 10 Core (8 performance), 32GPU cores)/MacOS 13.4;
b) iMac 27"/2015, 40.GHz i7/MacOS 11.7.7
That doesn’t fit with your statements about being able to run on what sounds like the same spec MBP that I use. Thoughts?
please see @jussi_laako previous comments about what will run. Now can anyone remind me HTF to install HQP 5 Desktop under Gnome on Ubuntu 22.04? And a plea to PLEASE include installation instruction links for each platform from the downloads page! [Edit: found my previous playbook on installation, but the need for a link/documentation remains].
Bottom line is that the only system I have that will run any DSD512, is an X470/AMD3900XT system running Ubuntu 22.04LTS. Even that won’t run ASDM7EC-super 512+fs. It also generates noise - assorted pops and clicks, so not actually usable as an HQP system.
@jussi_laako You state (as per previous comments) that an M1 Max MBP should run at least some of the DSD512 Shapers. Not that I can find, and these are ridiculously fast systems.
Interesting - what spec of M1 Mini? Thanks for sharing your settings - the only thing I was doing different was that I didn’t have the 20kHz filter on. Would that make any difference. Anyway, that combo is now working fine!
poly-sinc-gauss-long/poly-sinc-gauss-hires-lp through ASDM7EC-light 512f+fs at DSD512 works fine on my MacBook Pro (M1Max with 8 performance cores and 2 efficiency cores)
Software installation on each OS is typical way for the platform in question. I just consider basic Linux HOWTO document about package management outside of my scope. Internet is full of documentation on these topics already.
I’m working my way through the various combinations. Wouldn’t use my MBP as host, but it lets me test what does and doesn’t work. I even set up a new user specifically to ensure that other processes don’t interfere. On my basic M1 Mini, I’m now finding (HQP5) that DSD512 works with a range of filters and shapers (e…g Sinc MGa + AMS-DM7 512+fs). However, any DSD512 playout, whilst I don’t get the dropouts, I get popping and clicking in the stream - sounds a little like bad tracking on vinyl! Reverting to 44.1/DSD256 cures that.
Yeah, not something you would buy for running HQPlayer, unless you travel. When I travel, this MacBook Pro + iFi xDSD Gryphon is good combination.
For stationary HQPlayer use, Mac Mini with the new M2Pro, or Mac Studio with M1Max/M1Ultra is better fit.
Ahh, yes, my Mac Mini M1 with 16 GB of RAM is too weak. It is good for DSD256 with some basic operations. OTOH, it has only 1/4th of the memory bandwidth of M1Max and half the performance cores.
Dealing with OS package management is outside of HQPlayer scope, those are generic operations not related to HQPlayer. Different Linux distributions use different package managers (Ubuntu vs Fedora). Mac has it’s own way with DMG’s and Applications -folder. And Windows it’s own with installers.
My baseline assumption is that people know their way around the OS they are using. And generic topics are well covered on the internet anyway. For me to repeat same thing all over would draw my time to redundant non-related work, away from answering these questions or developing the software. Given that I have limited hours in a day, I need to have clear boundaries on what I do and what I don’t do.
Useful advice, thanks - I think I see an M2 Mac Mini in my near future. As for the software scope/UX stuff, I entirely appreciate (as do we all) and benefit your immense expertise in signal processing. After that, it is, as you say, a matter of priorities and background. In my case, I come from decades of focussing on making complex tasks and systems accessible to end users, be they experts in their own field or non-experts trying to make sense of what they’re trying to achieve. So we’re just coming to the same problem from slightly different places.
And, one more thing… …I’m trying out sinc-MGa+ASDM7EC-super at DSD256. This works fine with 44.1/16-bit Flac/44.1 MQA. It however doesn’t work with 48/24-bit Flac/48 MQA. Looking at the playout chain, MQA doesn’t show authentication for the latter. Any idea what’s happening here?
I should have explained further: MQA decoding works fine for most MQA settings (as per the first screen shot) - it’s just that with this combination of source encoding and HQP settings, it doesn’t appear to authenticate the MQA stream, and nothing plays out. If I take HQP out of the loop and drive the DAC (Gustard A26) directly from Roon, it works fine.
[Update]. I suspect that this may just be my Mac Mini M1 (basic spec) running out of steam. If I switch off MQA decoding and rendering in Roon (just leaving the core decoder on in advanced settings), then it plays out any MQA, downsampled to 96KHz, before HQP’s upsamplers kick in.
Your DAC is likely not capable of DSD playback at multiples of 48k? So this filter cannot used for 48k family sources when output is restricted to multiples of 44.1k. You would need to choose a filter that can convert to 44.1k family regardless of source (please refer to the table in manual).
That is MQA stuff and totally unrelated to any HQPlayer things. You can safely ignore such things. If possible, try to choose non-MQA (lossless) source, such as Qobuz.

From earlier posts, on Mar 17, it looks like you previously had an i7-12700 and it was already able to do ASDM7ECv2 @ DSD512? And so you upgraded the deskmini to a i9-13900 and of course can also do ASDM7ECv3 @ DSD512.
What additional HQP capabilities has the upgrade provided? Just trying to figure out what CPU to buy.
[Edit: the deskmini doesn’t have the power to run the 13900 at full speed so not sure what the point is - thinking about an i7-13700]
