AudioLinux and NUC Troubleshooting and Tuning

Summary of useful findings and recommendations

 

This section will be a living repository of useful info from this thread. It's very similar to a wiki and will be maintained by a small group of thread moderators.

 

Before you get started please refer to the Audio-Linux website to ensure you have the latest info and the proper versions of the OS. Audio-Linux.com  

 

**** Updated for AL 1.30 menu 118 or later.

 

  "First Run" setup for headless.  

 

Setup your NUC with a keyboard, mouse, and monitor to the NUC BIOS settings.  From the menu note the IP address of the machine to SSH into.  From a MAC the macOS terminal program supports SSH:

Then it is simpler to cut and paste into the terminal session. After entering the password for the audiolinuxuser you will be presented with the AL headless menu:

Option 8 takes you to the command line for the following basic setup.  You will need to be the Root user for this setup and the su command first:

 

su

 

Fix the time zone:  (this is my timezone - look in directory /usr/share/zoneinfo)

 

timedatectl set-timezone America/Chicago
 

Setup and Start NTP daemon (to keep the system time in sync)

 

*** the config file is now properly filled in.

 

Now Start the daemon

 

timedatectl set-ntp true

 

 

NOTE: Sometimes the system takes a little while to get synced up.
 

Set hostname  (this provides a unique name for the machine on your network.  Replace <NAME> with your chosen name)

 

hostnamectl set-hostname <NAME> 
 

Once the above items are set up your machine is ready to be configured for say a Roon bridge/endpoint. That is done using the AL menu.  To return to the menu do the following commands.

 

exit

menu

 

----------------------------------

 

For most of us, the following basic settings are key.

From the configuration menu:

6. START and enable Roonbridge

15. SET Realtime Priority to extreme

16. ENABLE ramroot (reboot after)

 

Return to the main menu and reboot the NUC using 

 

11 Reboot

 

------------------

Roon Server setup is a bit more complex and we will cover it completely a bit later.  The key is where you are booting from and where the Roon database is stored.  In general; say a 32gb OPTANE "SSD".

 

  • You have to partition the SSD into a boot drive and a storage drive.  
  • The transfer the USB stick install to the boot partition.  
  • Reboot from the boot partition.  
  • Do the basic setup. Timezone and name
  • Transfer the Roon Database to the storage drive
  • Start the Roon Server
  • .....

 

----------------- 

The machine will reboot and from the display attached to the NUC you can watch it boot up and load into RAM.  Once the AudioLinux menu is showing the endpoint should be available in Roon.    This completes the basic startup sequence.  The system is ready to start testing.

Guys, did any of you’ll use a grounding strap or anti static gloves while fiddling with the NUC? Is it ok to not use either and just make sure you’re touching some metal and not working on a carpet, would that suffice?

 

In the endpoint NUC, would it matter where you install the 4gb ram, upper or lower slot?

 

Is your NUC compatible with a smart TV or do we need to connect a Computer monitor? Larry had concerns about making it work on a regular Home TV.

It's the NUC7CJYH

 

Interesting. I tried powerimg it with the LPS1.2 at 12v but the LPS1.2 light kept flashing red whenever connected to the NUC (even tho the NUC was off). I wondered if even in standby the NUC draws too much power?

 

Haven't disabled as much as you in the BIOS so might try that.

 

Cheers,

We need to rope in @Superdad, for his first post here...

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 ??

Someone mentioned hearing an uptick in SQ updating to AL 3.0 lxqt, but Piero said he's just trimmed it down and there should be no difference in SQ.

Returning After an 8 month hiatus from everything audio, I have downloaded the latest links (headless & lxqt) from Piero but I'm struggling to copy it on the USB stick. If anyone's posted a link on how to do this (Mac specific) please point me towards it. Anyone have success copying the img with Etcher?
 
I use a Mac book pro as a server and plan on using the Celeron NuC as headless endpoint.

I tried, Piero sent me that link yesterday. But somehow I’m dragging my feet on the first step itself :(.. I’ve done it before on the  early AL 220.img file successfully but being away for 8-9 months I seem to be doing something wrong...

 

I need to get the first step right and then everything will fall into place or so I believe (fings crossed :)

Thanks @AnotherSpin and @bobfafor replying, that would be very helpful Bob looking forward to it.

 

Btw, Piero was able to troubleshoot  the problem e.g. the original file was 

audiolinux_350.img not audiolinux_350.img.gz, this is because unfortunately mac had decompressed the file after downloading it.

 

In any case, the latest versions of headless 1.5.0 and lxqt 3.6.0 are to be released today, so I might as well wait a few hrs & get those.
