Any suggestions for troubleshooting?

What @rickca said, plus some Acer laptops might need you to first create a password for bios, to be able to disable secure boot.

"alconf" is not recognized.

did you input alconf without the exlamation marks ?

1) does it matter which USB port is used for boot?

2) does it matter which port is used for asynch USB connection?

I'd use the rear ports for output (not sure if the front ports are connected via cables).

I would disconnect the fan, If no luck check if there's a low power setting in bios.

What do I need to be doing differently?    

Go into the console, type alconf there's a list of settings there.

I rebooted, but when I login, I still see 0.5 on the login screen. And, if I type alconf I still get the old menu. 

That's just to update the Kernel (engine) not the whole OS. I'm still on 0.3

Exactly, I tried to download the latest AL headless version but my credentials no longer seem valid.

Looks like Piero changed server or links, just email him for the new links/ passwords.

You can just leave it as NTFS with all your music pre loaded.

@greenleo made a guide no.4? To automount the drive so look at that first.

You will need to edit the etc/fstab file.

In lxqt you would use the root file editor (the pink one) in headless then it's nano.

There are many YouTube videos on basic nano use.

An easier way is to load lxqt desktop and then place your headless USB stick in the same machine. Then you can edit files from the headless USB. In a desktop environment.

However the file path will be different; run/media/audiolinux/audiolinux_mini/etc/fstab (same principle for other files)

Otherwise you will be editing the lxqt files.

For file transfers install WinSCP on your Windows machine and you can access your hard disc remotely which will now be located at /media/windows.

Lastly install Putty for console access which you can also open in WinSCP.

Yup. Using Roon.

You need to automount your hard disk (edit the fstab) Roon will not recognise the disk if its mounted after booting.

You need headless on both machines since that the best SQ and your controling roon remotely on your pc.

Enable roonserver on one and roonbridge on the other via alconf.

I like lmitche's idea of creating a document with all of your previous configuration changes listed so that you can quickly run through them...again.

and again.......and again.......and again...... etc.....etc.... thats why I'm stil on 0.3

In any event if you hear a difference between 0.3 and 0.6 its down to expectation bias ??

Do you know what the "high" and "critical" values represent? Are these bios settings for warning or are there historical values that have been previously reached... or none of the above?

The CPU is programmed to shut down at 100 degrees, to avoid damage.

I'm running 0.5 on a stock unit NUC7i7DNHE in RAM using extreme mode.  72 C° seems quite high.

 

That's probably the Tcase max temperature for a mobile CPU meaning once 72 C is reached the processor wil throttle ( reduce frequency) so that it doesn't go up any further. This will degrade the performance so ideally put it in a AKASA case to get it down to 42 C.

Clocks should be on all the time for best performance, it lessens the overall Crystals lifetime but we are talking 5 years +.

have both SPS500 and LPS 1.2. The SPS500 is a beast for quality current but it can't compete with LPS 1.2 device resolution when powering sensitive source electronics.

I have the sPS500 and lps1 both sound bright (I can't speak for the LPS 1.2) when compared to my Sean Jacobs 12v rail where I hear a much more natural, warm, spacious presentation.(in my particular set up) Your speakers remind me a bit of my audeze headphones, very sensitive to Hf distortion. Using a ISO Regen may fix that another option to explore is a different power supply.

Good power supplies behave much like the glass used for a telescope lens... the better the glass, the higher the performance that can be gotten out of the end product.

They also have a sonic signature, ultracapacitors don't sound the same as a toroid or  an smps, you will find in any review that an lps 1.2 has a brighter signature than the JS2 from the same manufacturer. They will also lose some of that clarity if they are struggling to provide the current required. The older HDPlex is not as transparent. A mundorf capacitor in a DC3 will impart a different sonic signature to a Nichicon or Elna in the sPS. With your speakers/ system  ( particularly your comments regarding the brightness of the NUC ) a Paul Hynes SR4, Sean Jacobs DC3 or uptone JS2 'may' be a better sonic match. To clarify I'm not stating that any of the power supplies mentioned are 'bright' it's about system synergy, the NUCPJYH is not at all bright here.

I"m using squeezelite-r2 with roon as control. Tried all the buffer settings both in roon & sl, but I also get the skipping and sometimes freezing. I'm wondering if the other version is a better match or is it only truly compatible with LMS?

I powered a 10W server plus a Mytek Brooklyn Dac/ headphone amp with a Y cable, with the sPS 500. On paper it's more than capable. A strange one.

Can someone help me configure the parted and mount commands needed here please?

you need to mount the data disc in the media directory eg. /media/windows ( doesn't have to be labelled windows)

you just need to edit the fstab with nano no need for all the mount commands then save and reboot.

add this line to the fstab:

UUID=xxxxxxxxxxxxxxx /media/windows ntfs-3g nofail,noatime,uid=audiolinux,gid=users 0 0

substitute the x's with your drives UUID

use the command: lsblk -f

His screenshot showed the disk is unformatted.

 

OK I assumed it was already ntfs.

I already had a formatted drive taken out of a windows machine with all my files on it. Easiest way is to plug it into a windows machine and format.

Parted is the only way I know  in command line, an alternative is to load lxqt and use gparted in a desktop environment there are simple sliders to resize the partitions.

for ext4 the fstab will differ:

UUID=xxxxxxxx /media/linux1 ext4 nofail,noatime,rw 0 2

[LTG2010]

You can also dowload Ubuntu live and burn the iso to bootable USB.

Launch and chose to try not install.

Go into the software centre and install gparted.

Then launch Gparted.

It was the bloody barrel connector! Figure it was a polarity inverter.

Glad it's sorted.

Thanks. Listening now on the SPS-500 and it's sounding great.

Zenith as server?

I should add that I cloned my USB drive from a USB2 to USB3 drive...

Did you clone a drive with ramroot already enabled? sounds like it's enabled.

Can someone explain how to do this?

You can use the dd tool.

@BigAlMc

To avoid confusion change the hostname of one of the machines so they are not both : audiolinux.

The file is located: /etc/hostname, just edit it (ramsave if youv'e booted in Ram)

or command:

su

hostnamectl set-hostname newhostname

 

Edit: Rajiv has listed this in his tips post 1st page.

Does it do the reverse? Create an image from a USB stick?

Its similar to Rufus 3, just load the image and burn to USB etc, I think the pro version might do the reverse, but you'll still need to save the current OS as an image first.

The easiest program I found to make USB-stick images or clone USB-sticks is the free "ImageUSB" :

https://www.osforensics.com/tools/write-usb-images.htm

With all these program they should recognise a DD image and burn it automatically. Sometimes (rarely) it does not happen also in etcher.

If that happens then try Rufus 2.18, which allows you to select the image type.
