Hi Alan,

 

Are you still using your SE as your server or have you booted that with AL too?

 

Got to say that I just find AL stupidly good whether on the NUC or your old Prestige 2. All the hard work I have done on my system has snapped into place ...find myself listening for hours ...and absolutely no trace of upgradeitus.

Hi Martin,

 

Yup, I got the NUC running as endpoint but with my SE still running as Core. So whilst it sounded amazing its hard to tell how much is the AL ramboot NUC versus how much is the SE and just using Roon in its supposedly optimal config of separating server and player duties.

 

But it's early days and I intend to find out ?

 

I did play around a little comparing SE direct to DAC, SE to NUC to DAC, and both via my TX-USBultra and the results were very promising.

 

Need to get the NUC working on my LPS1.2 next. And also need to listen with Core duties elsewhere in order to better compare the NUC to the SE.

 

Plenty fun ahead.

 

Still impressed that you took the Prestige to such heights!

 

Cheers,

Alan

Thanks to a lot of help from Piero, I was able to get my NUC8i7BEH running headless Al with 8 GB of RAM (diskless - running Al and Roon DB in RAM). But even sitting idle, I am getting a message that reads "Core temperature above threshold, cpu clock throttled (total events = 1). Then a series of lines, then NOHZ: local_softirq_pending 80. 

 

Anyone have any suggestions of a possible mis-configuration I've made?

 

Here's a screenshot:

If you running in extreme mode, you are likely to get it even when doing nothing. If not, then are you running Roonserver which is scanning a newly configured library ? If yes, then you will likely get the throttling message as well.

Type: sensors

 

This will let you monitor the cpu temps, my nuc7i7bnh has hit 92° (extreme mode dsd512 +convolution) but hasn't throttled once so I'm guessing you're cpu temps are sky high which, as suggested above, might be down to a new Roon library scan being performed in extreme mode. 

 

Type: top

 

This command gives a task manager type view of running processes and cpu usage. 

 

Type: - 1 (once you've typed top) 

 

This will list cpu usage for each core. 

 

Useful as you might see cpu usage as being over 100 %, which is misleading as in reality each core has its own '100%' allowance. 

 

I was worried because mine was at 120% but as it turns out my dual core i7 was running at about 60% on each core. 

 

Much less worrying.

Try use the standard mode when the headless is idle. 

 

If you're using the headless as a Room server, I guess it's very taxing and the temperature will rise.  Probably much lower if it is used an Roon bridge (end point without Roon certification).

Hi Alan,

 

TBH it was a zero risk play. By disconnecting the SSD from the power I reverse the change in about five minutes.

 

When I first got the box it had Vortexbox's newest version of the OS ....but, I could only connect to one USB at a time, and I have 4x512GB. I ended up loading up their latest open source version, which is years old. This allowed to me mount the four USB sticks, but also degraded the sound quality very slightly; still a LOT better than vanilla Ubuntu which I tried first.

 

AL more than recovered that lost quality, and saved me buying a second NUC.

I am running headless Extreme for:

 

1. Squeezelite - my NUC is barely warm. CPU temp = 43 C

2. LMS - Server is warmer to the touch. CPU temp = 80 C

 

The former is still in its supplied case with the fan.

My first attempt to install AL headless on my Acer laptop.

I burned the image on a USB flash using Rufus but when I boot the laptop I am getting this error message

"Security Boot Fail"

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.

Mozes,

 

In the UEFI,

 

Switch off the security boot.  Choose Linux as the boot OS if necessary.

 

tapatrick has done brilliant screenshots.  Don't waste it.

Thanks @dev @greenleo @devrettib2001 for the reply. It is a new library, so maybe that is the cause of it.

 

I haven't switched to extreme mode yet, so this is happening in standard mode.

I am running in ramroot. I would like to try Extreme Boot but when I choose it in alconf I get an error "Boot default is not set to Extreme".

 

I figure that I missed a step?

Sorry, it is a typo in 0.5. Not instead of now.... It will be corrected soon.

 

You can check status... rebooting

Ok guys, I managed to boot AL from the USB flash. Thanks fr your help. It worked after I switched off secure boot from BIOS.

Then I chose extreme mode, but when I type the command "alconf" I got the message that command is not recognized. I tried another mode called Audiolinux BFG and still got the error that "alconf" is not recognized.
