Oscarhuge Posted September 1, 2020 Share Posted September 1, 2020 Hi Piero @hifi25nl in version 2.6.1, does enabling the "Realtime Expert Configuration" and the "ALSA system wide configuration" still benefit the sound quality? If it still does, could you please give us a reference setting? Cheers.😉 Link to comment
hifi25nl Posted September 1, 2020 Share Posted September 1, 2020 ALSA system wide configuration is there only for special needs. I wouldn't add anything I think that enabling Realtime Expert Configuration could give a substantial improvement. You can check the configuration file /opt/configuration/realtime_custom.sh and eventually edit it as root Remove # in front of each line if you want to enable the corresponding configuration I would enable all (in last Audiolinux versions the # is already removed in front of all options) The option with cpumask should be enabled only if you have isolated some core.

cat6man Posted September 2, 2020 Share Posted September 2, 2020 hi folks, i've just moved from a single NUC solution (LMS & squeezelite running in ramroot) to a two PC solution where the LMS server is running on a separate ubuntu machine which is also my sageTV server/DVR. moving to two machines made a noticeable improvement in sound quality. note that for now, the LMS server is not running under AL or in ramroot, just plain old ubuntu. my configuration is LMS (on ubuntu)==>edgerouterX==>etherRegen(opt out)==>opticalModule==>AL(squeezelite)==>slimrunUSB==>totalDAC while doing some testing/comparisons with some other software, i turned on hyperthreading and turbo boost and turned off low power in Bios. i don't know if that is optimum for AL though as I was running my previous single NUC solution with HT and turbo off and low power on. since i'm running headless, it's a pain to change bios settings and will probably wait a bit before i do that. has anyone here done comparisons with those bios settings on/off for AL recently? @Pierro: do you have any recommendation? has anyone compared a two nuc solution with AL on both server and endpoint, versus just on the endpoint? (i.e. should i get a 3rd nuc for just the LMS server?) thanks Link to comment

Just updated! @cat6man If I ever have a Ferrari I would not lower the power to pay less taxes... A good system (from electronic point of view) does not have limitations if power supply is of high quality. There is no evil in high power... I guess that some people are forced to lower power lowering CPU frequency because of absolutely inadequate linear power supply. Those power supply would have high ripple if used near maximum capability, much more than powerful SMPS. People should read the CPU documentation to see the minimum power requested. Moreover on Audiolinux, if you want a very good latency, a good power is necessary. Audiolinux configuration should follow the hardware capability. Do you have a PC with weak CPU? Don't ever think to extreme configurations, the sound will be congested, aggressive and sterile. On the other hand if you have an AMD Ryzen Threadripper feel free to go up to the most demanding settings.

Popular Post frederick184 Posted September 15, 2020 Popular Post Share Posted September 15, 2020 Big thumbs up to @lmitche for the latest remote AL update to my server, plus his own software configuration changes. I can honestly say this latest change has made the biggest difference to my system in the 2+ years we have been working together. A big increase in depth, space around performers and instruments. Everything is much easier to follow. This man knows how to get the best out of AL. I use Roon only. Colin lmitche and Superdad 1 1 Link to comment
sig8 Posted September 16, 2020 Share Posted September 16, 2020 I have been using AL for couple of years now. I was using RAMROOT, but at this point it does not fit on 8gb RAM, and Miska from HQP suggest it is not best to use HQP in RAM mode. So my question is if AL can be installed on an internal Optane drive. Link to comment

For a headless installation, AL fits into 8gb using ramroot with RoonServer and Hqplayer embedded without issue. Headless will also fit into a 16 or 32GB Optane NVME drive configured as an SSD. I recommend the larger of the two as the extra space can be useful for other things like the Roon DB. I haven't booted AL with the GUI for many years and can't speak to that. I am sorry I can't be more helpful. Larry Pareto Audio aka nuckleheadaudio Link to comment

I can add RAM to both or install on Optane. How you install on Optane? Thanks. Link to comment

Here is a reference that explains how to use DD: https://wiki.archlinux.org/index.php/Dd#Disk_cloning_and_restore Also, Piero has some copy commands on the headless AL menu that may work as well. Are you saying that headless doesn't ram boot on a 4gb RAM machine? If so, another ram stick is the easiest solution. Headless definitely boots on a 8gb machine. I don't know about the GUI version. Maybe Piero can chime in? Pareto Audio aka nuckleheadaudio Link to comment
hifi25nl Posted September 16, 2020 Share Posted September 16, 2020 With 4GB RAM an option is to remove some packages, at the cost of not being able to install extra kernel modules or compile some applications: yay -R gcc linux-rt-headers or yay -R gcc linux-rt-bfq-dev-headers (if you are using linux bfq) Also the ramroot configuration file /etc/ramroot.conf should be edited to different values. Default is # minimum MiB free ram: ram_min=500 # minimum MiB free zram: zram_min=250 # preferred MiB free ram: ram_pref=4000 # maximum MiB free ram: zram_max=1000 After disable ramroot ramroot -D and re-enable it ramroot -E AudioLinux --> https://www.audio-linux.com developer of AudioLinux realtime OS Link to comment

hifi25nl Posted September 16, 2020 Share Posted September 16, 2020 No, that should be the max free zram. Zram is a virtual hard disk and that line define the max free space you want to leave on it. You can go down to 250, if needed. AudioLinux --> https://www.audio-linux.com developer of AudioLinux realtime OS Link to comment

hifi25nl Posted September 16, 2020 Share Posted September 16, 2020 You can test the RAM with the command free: free --mega before enabling ramroot After you know what could be a good low value, maybe 400 is enough AudioLinux --> https://www.audio-linux.com developer of AudioLinux realtime OS Link to comment
