RME HSDPe AIO gets polluted by MoBo - any remedies?

Post by cupakm »

Hi all,

I've got an RME AIO (rev. 1.4) plugged into Asus PRIME H270-PLUS (rev. 1.02, BIOS 0808 x64, firmware 11.7.0.1229) with Intel i5-7600T and sadly, I can hear CPU load in earphones - for example opening / dragging windows, moving mouse pointer, encoding video, or compiling my DAW from source... total idling results in silence, on any action taken the noises reoccur.
This irregular high-pitched crackling is already present during the boot, in its very soft volume even before OS starts to boot up, just a little while after that one loud click when PC gets turned on.

I guess it is the motherboard, because on its factory settings the noise was quite heavy, but after I sort of desperately disabled all the power-saving and voltage-changing and whatever settings in BIOS, the noise got a lot quieter and somewhat more tolerable, but is still there!
Disabled settings are:
- ASPM (active state power management), PCH DMI ASPM, DMI link ASPM control, etc.
- Intel SpeedStep
- Intel Turbo mode
- CPU C-States
- CPU SVID support
- on-board audio
- MLC streamer prefetcher
- adjacent cache line prefetch
- SGX SW guard extensions
- TCC offset time window
- IOAPIC 24-119 entries
- CFG lock
- serial port
EPU & performance mode: set to Performance mode

I also don't think it has anything to do with my OS Ubuntu Studio 17.10, because I've already had flawless operation under this OS (with AsRock AM1H-ITX MoBo and AMD 5350 CPU in it, though).

What I could try changing are:
- CPU LLC (load-line calibration)
- CPU graphics LLC (I'm using integrated GPU)
- CPU power phase control

But I'm getting pretty skeptic. And otherwise out of ideas. I've tried swapping PCIe ports also and disconnecting CPU fan (I can go fan-less) - no noticeable changes.
Any suggestions?

PS: I also miss Out6 signal (that nice subwoofer rumble) in HDSPmixer - it just isn't there, although HDSP-mixer settings are loaded from the same file from my previous OS install and ALSA-mixer settings are also the same. But the noise is far bigger issue now.

System info (my previous install also used snd-hdspm, not snd-hdsp, and it was ok):

Re: RME HSDPe AIO gets polluted by MoBo - any remedies?

Post by Brynildsen »

My prefered setup is so minimalist that is looks worse than a windows machine from start 90's.. No DE, no icons, no menus, no network manager, no noting, mostly just scripts doing stuff I want it to.But I love it. I'm a terminal dude anyway, and don't like distraction.. And it is perfect as a studio environment.

But I also have a htpc in the living room with KDE running all kinda fancy composite stuff, bloat, animated this and that, shadow, transperancy and a bunch of weird widgets. I hate KDE, but my girlfriend can navigate it with a mouse without knowing anything about linux. I can hear noise in my speakers from all this bloat.. Especially stuff like system monitors, network speed graph monitors, wifi applets/network managers that is constantly running and scanning. I don't know how your desktop looks, but those processes are a bad combo with audiophile people.

So my suggestion would be, try out a simple lightwindow manager just to test it and open up your music software there.. Disable all unnecessary stuff. Look at it like building a race car. Strip it of all unnecessary weight, it is not meant to be pretty and comfortable, just reliable and fast as hell.

Re: RME HSDPe AIO gets polluted by MoBo - any remedies?

Post by cupakm »

I've started this thread https://www.forum.rme-audio.de/viewtopic.php?pid=127010 at RME's forum.

In the end, it was poor power supply:
The problem seems to be solved. It wasn't fault of motherboard or the BIOS settings. The power supply was to blame. I've tried Seasonic SS-400FL2, which whined a little - not under standby, but when the computer was on. And it did even under load, not only when CPU was idle. It was faint, but irritating enough to be returned. Same story for Silverstone SST-NJ520 Nightjar. Then I've tried Fortron Aurum Xilenser 400W, which is indeed totally quiet, and fed by Furman M-10x E power conditioner, strange noises went away.
I had to switch more PSUs and tried the above mentioned power conditioner, but now its done - totally quiet and noise-free.
