Euphony OS w/Stylus player setup and issues thread

[Nenon]

Alternatively, if you don't want to wait for their support, download a new image from their web site and reinstall Euphony.  I had something similar happening to me once, and I think I created a new USB drive.

@lwr - according to the manual, it should be audiouser/euphony.

 

Wow! It works! It seems I have missed that or the manual at all.. lol 🤔

 

Thank you! 🙂

[lwr]

Got it.  Thanks

Thank you for that info. Very useful. I did not think that was there before, but I am not so sure anymore. 

I guess they protect the root password.

Yes, I can not edit the rtirq.conf file with audiouser/euphony.

I followed the instructions to make a euphony bootable usb stick. After the initial menu with Euphony as the first (and chosen) option, the boot gets stuck at:

 

ERROR device UUID=[.... long string] not found. Skipping fsck.

mount: /new_root: can't find UUID=[.... same string]

You are now being dropped into an emergency shell.

sh: can't access tty; job control turned off.

I normally use this PC to boot into Gentoo(Player) from a stick and load everything in RAM. There is no SATA disk in the PC. Is this a setup that would not work with Euphony?

I tried to scan the thread but I can’t seem to find how to load convolution filters to HQPlayerD. Can you point me to the guide please? Is this even possible with Euphony?

I fear there is no such guide. You don't have full access to the HQPe settings with Euphony. You could open a ticket and ask Zejlko to make the access to the HQPe web interface possible.

Ahh...the unobtonium SR7 comes into every other discussions 🙂 You lucky chaps!.

 

Can anyone tell if the differences from other good quality PSU is like splitting hairs or the improvements are massive ? How much in terms of % are we talking about ? I am trying to guesstimate how much I am missing 🙁

 

On the other hand (and playing devil's advocate), maybe all these money spent into motherboard, CPU, chassis, Network/USB audiophile card, unobtonium SR7, expensive DC cables and endless tweaking is not worth than getting a reference server like a Auralic G2 which will mostly cost about the same. Anybody compare yet ? 

 

I have just been reading the thread and saw this post. I had the G1  (a bit more than half the price of the G2) for a couple of weeks, it was a little more transparent than my fanless ITX build when I could run it directly connected to my usb HD library. However it stopped working in this mode, it kept losing the library.  Dealer said the best option was to use NAS, SQ went down hill when I had to stream via ethernet . I was not inclined to keep it, the significant improvement I was hoping for did not materialise.

 

Since then I have been treading the Novel improvement path, I use my ITX as a server to my NUi7 client with audiolinux running in RAM. Now I do have the massive improvement I was looking for, way ahead of the G1 for a similar outlay and plenty of options for further improvements.

 

I know the G2 is a step up from the G1, however from what I have read they are pretty close in performance and the nature of the sound produced.

 

Back to Euphony  - would it worthwhile putting it on my server to stream to the Audiolinux NUC?

Hi All

 

I have been playing around with Euphony running Roon and HQ Player. 

 

The interesting things here is I can run XTR filters and new ASDM7EC on my Windows Server 2019 using AO & Fidelizer, albeit my processor running at 90%. no buffer

 

The above filters simple will not on Euphony, even with buffer set in HQ player. Stutters and Stutters. Try hours trying to resolve. 

 

So here's my question, if Euphony is optimized just for music then why can't it do what Windows server is doing?

 

You think USB drive got something to do with it?

 

Unless anyone has any ideas I'll give up and go back to Windows

[davide256]

looking for instructions on how to make an  Optane M2 stick into an SSD for Euphony on i3 NUC, can't seem to find that posted. Anyone know where

I might find that?

[ASRMichael]

I’m planning on an  Optane too! sure it’s simple as connecting the Optane, then insert usb euphony, complete installation to hard disk, = your new Optane,

For folks who are using Euphony OS, you may be interested in this. Željko now has an experimental build where he has implemented ramroot support, which can be enabled/disabled from the Expert Settings area of the UI.

 

I've been trying it out for a couple of days, and my results so far have been promising. Just like in AL, enabling ramroot (loading the root partition into a RAM disk, and then booting from it) results in a definite uptick in sound quality.

 

Željko wants to get a few more proof points before releasing it, and asked me to convey this call for testers. If you're interested in testing it out, and reporting your results here in this thread, please reach out to him by opening a support ticket in the Euphony system.

So how can I  benefit from the ramroot option if I already run Euphony on an internal Optane drive?

Sorry if my question is a  bit dumb!

Not a dumb question, and no apology necessary! 

 

Loading the OS from an NVMe SSD (which is what your internal Optane drive is) is different from Ramroot:

• In normal mode, the boot loader will load the operating system (Euphony or AL, since both are based on Arch Linux) from the partition on the SSD that contains the root filesystem, i.e. that contains the / filesystem.
• In Ramroot mode, the boot loader proceeds with an extra step. Early in the boot process, it creates a RAM disk partition (/dev/zram0) in memory, copies the contents of the / partition from the SSD to this partition, and then completes the boot from this RAM disk partition. 

What this means is that the filesystem containing the kernel and the OS files is now completely in RAM.

 

Why exactly this sounds better is yet to be explained, although a lot of theories abound, having to do with reducing the latency of OS operations due to all OS files being in RAM.

But Euphony OS cannot run in RAMROOT correct ? I know AL can.

It was also once stated that the prime reason for using Optane was that the latency was comparable with RAM (and the noise comparable with USB).

I am in a process of trying ramroot with NAA endpoint Euphony. First impression is very good! With this I want to confirm a definite change with enabling ramroot.

Is this feature available on the Trial license. I can't seem to find the option for Ramroot in the Expert settings.
