After Ramboot Enable In Al Headless 0.6 with Putty then I need to reboot. But whats the reboot command and where should I be.

Thanks Monge

 

Reboot with the command:
sudo reboot

 

I now have a Word document with all of the commands and tips from Piero's web site and the two threads here on CA. Very useful.

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 +.

I will get the plato X7D. This must a very effective case if it gets it down to 42 °C passively.

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.

[afrancois]

if the date and or time are wrong in 0.5, type: timedatectl set-ntp true
Verify with: timedatectl status

A couple of the word docs have been created. Worth posting them minus any private details?

Basis for an AL command glossary?

Or these just settings for individual users and referenced from the AL web site?

My NUC7PJYH in Akasa Newton JC case reaches a stable temp of just 36C running Roon Bridge in Extreme2 mode (AL0.6). This is with speedstep disabled so no turbo’s and a fixed clock freq. of 1.5GHz for all four cores.

 

I used thermal paste I still had from an earlier build (Arctic Silver 5) between the CPU and the alu block in the case and also the alu block and the case it is screwed on to (after removing the original paste there first of course).

 

The build (or transfer of the innards of the NUC case into the Akasa) was very easy especially comparing with a complete regular (mATX/iTX) build into a Streacom fanless case. So don’t panic (for those to who this applies), just do it!

Thanks.

Now I could hear how my NUC7CJYH with ramboot enabled.

Wow...

Thanks to Roy, Larry, Piero and everyone Else here for all their hard work ?

 

I am using my Nuc as a Streamer for Tidal with MPD and UPnP enabled and installed with an Android Phone with Bubble UPnP App.

 

I ned another NUC for Roon core.

 

Cheers Monge

 

 

[austinpop]

FYI - Piero @hifi25nl is looking into making a true OS updater starting with 0.7! 

 

I too have a doc with my customizations, but I'm lazy to reapply.

[Monge]

I have a Strange thing going on here with my NUC7CJYH with 2x4GB ram running AL Headless 0.6 with Ramboot Enabled (rebooted) with enabled MPD and UPnP services and installed.

I start the Bubble App and choose a playlist In Tidal and start playing. Then I pull the   

AL USB stick and the music keep playing but the startnumber on my Android Phone like freeze and I cant change number or playlist. But the music on the playlist keep playing. Only that I can not do anything to control it.

 

Cheers

For those who are running headless and use a Windows machine.

I'm using Putty for remote login and WinSCP to navigate the AL filesystem.

 

WinSCP

 

I 

 

It allows you to navigate the file system of an AL headless.

 

For example, by simply double-clicking on alconf in the /usr/bin folder you get the content in a Windows.

 

the arrow left of alconf says it's a symbolic link to /opt/scripts/alconf.sh

 

As I'm still in 0.5 and some have been able to download 0.6, it would be nice to have the content of alconf.sh :-)

Brilliant @afrancois,

 

I use WINSCP at work but hadn't occurred to me to use it to SSH into the NUC.

 

Would this work for transferring music to an AL NUC server?

 

Thanks,

Alan

It has also been a while since I have used WinSCP. My previous linux endeavors are far back in the past.

 

No problem copying files from my NAS to the NUC's memory (running AL in ramboot)

 

 

Have also successfully mounted audiolinux/home/audiolinux/music in Roon.

Then I searched in Roon after Hells Bells and of course, I found two entries. Be right clicking on the icon right of the title you can query the file location. Take the one that's in memory and compare with the one coming from the NAS.

I haven't done the comparison yet. Perhaps put something more audiophile into the folder :-)

Another option for folks to use for personal use is MobaXterm, which you can use to start a SSH session but on the left side it also gives you the option of uploading/downloading files.

[afrancois]

I've copied a full album on my drive d:\music-memory and changed the artist to MEMORY-artist with mp3tag and copied the files using WinSCP to the NUC's memory. After that go to overview in Roon and you will see the album as newly added. You can play it from memory now.

Can you open a file, edit it and then save it back to AL?

Yes, very easily. Double-click to open the linux file, modify and save.

@hifi25nl,

 

Some questions after reading: http://www.audio-linux.com/html/realtime.html

 

I’m running just Roon Bridge on my AL headless (0.6) NUC (it’s the endpoint) and I’m seeing these related processes :

 

root       544     1  0 17:41 ?        00:00:00 /bin/sh /opt/RoonBridge/start.sh

root       549   544  0 17:41 ?        00:00:01 RoonBridge --debug --gc=sgen --server RoonBridge.exe

root       590   549  0 17:41 ?        00:00:10 RoonBridgeHelper --debug --gc=sgen --server RoonBridgeHelper.exe

root       595   549  0 17:41 ?        00:00:00 /opt/RoonBridge/Bridge/processreaper 590

root       601   549  0 17:41 ?        00:00:39 RAATServer --debug --gc=sgen --server RAATServer.exe

 

In the rtapp.conf file (below) I see RoonBridge is listed but not RoonBridgeHelper or RAATServer. Since these have used more CPU time, would it be beneficial if I/we added those processes to the applications list?

 

Also I see —debug in the process list? Is that necessary or better said would it be ‘leaner and meaner’ to not use those switches?

 

Thanks in advance. If you’d like me to email you instead please tell me. It’s just that I though this might be beneficial to other users as well.

Some scripting with WinSCP to automate your flac file copies to memory

 

script1.bat

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /log="D:\WinSCP-Script\WinSCP.log" /ini=nul /script="D:\WinSCP-Script\script1.txt

Good questions. I actually went ahead and added RAATServer (and squeezelite) to the list. Can't say it had an audible effect!

 

The --debug question is a very good one. I hadn't even noticed that.

@Dev if I recall, you have the NUC8i7BEH, which is the model I have. 

 

I am running mine as a Roon server headless with AL + the Roon db in ram. I have a monitor hooked up while I get it fully configured, but I'm finding that it almost always throttles (cup clock throttled) - and it's just sitting idle. I have it running in Standard mode as well. Does yours typically throttle? I wonder if it's because I have my Roon db loaded into RAM as well.

 

@lmitche @austinpop any ideas how to solve this issue? I'm thinking about getting Optane memory to store the Roon files on to see if that solves the problem.

 

 

 

When you say "throttled" what do you mean? What metric are you referring to, and how are you measuring?

 

If on the off chance you are referring to 100% CPU utilization, then perhaps it's just the initial scanning of the library and the building of the Roon DB.

On the monitor, it's showing rows of information that read "Core temperature above threshold, cpu clock throttled (total events = 1), then several rows saying "Package temperature above threshold, cpu clock throttled (total events = ?

Ahh - looks like a heat issue. Not had that myself. Hopefully others can elaborate.

 

Are you in a fanless case?

No it's the stock case until Akasa makes a case that will work with this model.

 

@Dev have you experienced this with yours?

what does the command "sensors" give you?
