AudioLinux and NUC Troubleshooting and Tuning

@hifi25nl Piero,

 

Wondering if you could help with this. I've been enjoying Audiolinux on my NUC7i7DNBE greatly, and have been using Roon Bridge which always connects without any issues, 100% reliable.

 

I used to love using HQplayer before I moved to Audiolinux. With audiolinux, switching to the NAA service, I keep getting dropped connections with my HQplayer computer which is connected to the same Brocade ICX6650 switch. It takes a while before the HQPlayer desktop program can recognize the AL NAA.

 

I assumed this was a problem with HQP, so I posted in the HQP forum, and Jussi suggested using his NAA image to boot. Using that, it's 100% reliable with the same exact hardware, so I think in my case it is some Audiolinux setting which is off.

 

Any suggestions? I have 4GB RAM on my NUC which should be enough for NAA. Not sure why the connection is so flaky.

 

Thanks!

Yeang

I am running your same config and it is working just fine, as a matter of fact my system is "multihomed" which poses other issues with connectivity and it is just fine. Let me ask you are using HQP Desktop or Embedded HQPe? I'm on HQPe but the discovery engine it is the same I believe, Jussi can confirm that.

1. Be sure you are not "blacklisting" any modules in /etc/modprobe.d/blacklist.conf

2. In console mode send the output of "networkctl" and "ip addr show"

Could well be the blacklisting. @luisma @AnotherSpin @hifi25nl thanks so much for the tips.

 

I'll go back to a vanilla install and see if it works.

 

How much RAM do you guys have on the NAA machine? I have only 4GB, wonder if enough for NAA (it is enough for roonbridge for sure).

 

I use HQP desktop 3.25 not the embedded version.

 

@luisma I had a multihomed setup for a while, Miska yelled at me for that. It was too much trouble so i quit using that and went back to waiting for EtherRegen lol.

I have 4 GB on mine, Miska yelled at me too but reality is multihomed with AL works and lately Miska's NAA image was giving me issues, his image is great but cannot be change

True, but Piero had OK'd 4GB of ram for headless Roonbridge with Ramroot... this could be an issue with NAA i guess.

 

@hifi25nl Piero, do you know if 4GB ram is enough for NAA, with ramroot, using AL headless? 

 

It is enough 4 GB, send me the output of the commands I sent you before

By some reason I like Jussi's NAA image a lot, even with comparison with both AL and Euphony.

 

He optimized his image for NAA usage so I guess it could sound better, as of now I have no comparison point, last time I tried the image it failed because of the multi homed and tried many things on the server side but could not get it to work.

Looks about right. It is configured as DHCP right?

IPv6 and multicast enabled

 

Just for testing would you like to configure it as static?

 

edit as root the file

nano /etc/systemd/network/eno1.network

 

[Match]
Name=eno1

[Network]
Address=192.168.1.20/24
Gateway=192.168.1.1

 

You can select a different IP that doesn't conflict with your dHCP pool and configure the gateway which I'm assuming is 1.1

MAybe you did this already

That's encouraging. Time to take a closer look at my network... I have a feeling it could take some time to figure out. 

 

Thanks for the reply 

The content you are upsampling is it streamed, local or both? Is the source content always Redbook or hires? And do you have multihomed systems with wireless? Sometimes you think you are using a wired connection but the pc might be by means of gateway, routes, interface preference selecting wireless instead of wired.

Still struggling to get  Audiolinux on the NUC to recognise the directly connected server worked fine with Ubuntu. I can share the internet from the server  but no network? Are there any network tips? 

Piero has been helping, he is on holiday at the moment, so dont want to pester him too much. 

You running multihomed? wireless to the internet and then network to an NAA? sorry not much info, I am running that config I just mentioned

cat /proc/asound/cards

Hi Gavin, this specific file is empty in my case

cat /proc/asound/cards

[root@alsvr audiolinux]# cat /proc/asound/cards
--- no soundcards ---

 

Maybe has been moved to alternate path need to look

 

[luisma]

I'm having a weird issue with the latest version, downloaded today 2.1.1 and updating the menu is fine however updating the system I'm getting errors (see below) so the process ends but when I do an update again it starts again and fails.

 

There is space on the disk

[root@audiolinux audiolinux]# df -H
Filesystem      Size  Used Avail Use% Mounted on
dev             2.1G     0  2.1G   0% /dev
run             2.1G  730k  2.1G   1% /run
/dev/sdb2        15G  2.4G   12G  17% /
tmpfs           2.1G     0  2.1G   0% /dev/shm

tmpfs           402M     0  402M   0% /run/user/1000

 

So I don't know if it fails because the packages are not available for some temporary problem or something else

 

@hifi25nl can you please take a look Piero?

My impression was that a great linear PSU paired with a wisely tweaked NUC7 was sort of state of the art. Now I'm curious :)

Like dctom stated every system is different,
I started with the high powered nuc powered by an LPs 12V, then added an endpoint (Allo bridge) powered also by the LPS (7V) there was an improvement, Allo stopped supporting some DACs on their old kernel so replaced the endpoint by a Celeron Nuc (12 V) sounded subjectively like the Allo, maybe not as good, replaced the whole system by a single high powered computer and sounded like the Allo maybe a little better, this PC without the LPS but the HDplex Atx power supply so that's what I'm running now, I think the USB shielding quality on a good motherboard surpasses the USB on the Nuc and IMO that makes more of a difference, I was planning to power the PC with an SR7DR but still waiting on that.

Let me say this, in my system and IMO the change I made that makes most of a difference keeping of course speakers Dac and Amp the same, it is HQPlayer, that have made more difference than power supplies and nucs, with the high powered computer I have access to "better" resampling. YMMV

Hi Piero:

Have you experienced (or someone) that after configuring and getting ready AL 2.9, enabling RAMROOT, booting successfully, all the sudden you cannot longer boot from the USB flash drive, if I mount /dev/sdb2 on some other Linux box it shows the contents as normal but if I mount /dev/sdb1 there is nothing there, it just stopped booting, I can of course redo the install but don't want to fail again, could it be related to the RAMROOT config? just curious

 

[luisma]

I'll send you the fdisk output from the other system, there is no boot at all, just that the device is not bootable, I am using UEFI of course, and it worked initially even after enabling ramroot but just suddenly went into that, I just build another system but would like to troubleshoot the failing one

If you have the same output as above

Same output but like I said there is no boot error or message, just no boot at all

[luisma]

Piero for prioritizing the enp1s0 adapter before the file to be edited was rtirq.conf adding the adapter on the RTIRQ_NAME_LIST, is this still the case?

or should the rtnet.conf file be used adding INTERFACE="enp1s0"

 

RTIRQ_NON_THREADED has "rtc snd" this basically instructs these processes to use all cores but not threads or does it limit the rtc and snd apps to be single core?

I would check first http://www.audio-linux.com/html/boot.html

Piero I was able to boot initially, update menu, update kernel, update system, then customize a few things like realtime processes and such, then ramroot, after ramroot I was able to boot, did a clean up, saved the system and then I wasn't able to boot anymore, I think you are assuming I cannot boot the image, of course I could, it is just after that for no apparent reason the system stopped booting

Now there is the option 1 "REALTIME MANUAL ASSIGNMENT configuration" in Expert menu where you can set priority without manually edit the files that are

/etc/rtirq.conf

/etc/rtnet.conf

/etc/rtapp/rtapp.conf

Thank you for the detailed explanation, now I get it ...

You should check the content of mkinitcpio.conf as suggested

1. Update Menu

2. Update to later RT 5.11 kernel

3. Update system

4. I have COMPRESSION="gzip"

 

That was not the issue something else was, if you are interested I still have the USB flash and it is accessible, but I'm already running another install so I'm fine
