luisma Posted November 18, 2020 Share Posted November 18, 2020 @hifi25nl something happened yesterday, for some reason at boot AL is detecting the wireless adapter (Intel) as wlp6s0 instead of the initially detected at installation wlp7s0, any idea why all the sudden the OS decides to use a different device?

I added a rule, this is a PC with no video card, on a different part of the house and fixing it takes some time, relocating parts etc. so I just tested it and works In my case echo "SUBSYSTEM==\"net\", ACTION==\"add\", ATTR{address}==\"8c:c6:81:f0:eb:0a\", NAME=\"wlp6s0\"" > /etc/udev/rules.d/10-network.rules Does it Thanks Link to comment
Csaba Posted November 22, 2020 Share Posted November 22, 2020 Could you please advise if 16Gb Optane Card is sufficient for the following?: - Audiolinux headless, - Roon Rock (currently 1.500 albums, which will increase to 2.000-2.500 in the following 1-2 years), - HQPlayer (desktop or embedded, not sure which version). I would use 16 GB RAM and probably run Audiolinux in RAM root mode. Thank you for your advice. Link to comment

You may be able to squeeze everything into 16gb, but it is close to the edge. For the $30 price differential for the 32gb version, it doesn't seem worth the risk of running out of space.

cat6man Posted December 4, 2020 Share Posted December 4, 2020 hi folks, i'm thinking of an end of year project for a car-based audio music server to run AL on a raspberry pi 4 w/ 8GB of ram. i'd like to use usb out to a small high quality DAC (starting with usb to my current Fiio portable music player that currently provides music in my car)........maybe something like an iso-regen in between, good LPS to RPi and accessories. based on my home system optimization, i'm planning on using audio-linux wtih LMS/squeezelite using a large buffer and running in ramroot and a large attached usb HDD............another alternative is hqplayer embedded + NAA. control will be via squeezer app (or hqpd controller) via a wifi connection to the RPi. has anyone attempted something like this yet? i don't see anything on AS so links to elsewhere would also be appreciated.

cat6man Posted December 8, 2020 Share Posted December 8, 2020 progress report: i now have LMS and squeezelite running under A-L on a RPi-4 (w/8GB ram), output to a GeekOut DAC and music stored on a 8GB usb stick. RPi powered by standard ac wall wart. next steps: 1. add large 4-5GB usb HDD for music storage (can RPi power it?) 2. replace wall wart with portable battery backup capable of 5v @ 3A 3. listening and squeezelite buffer optimization (**) 5. run A-L in ramroot (more listening) 6. add iso-regen between RPi and DAC (more listening) ** i ran into a problem setting up. when selecting DAC and setting buffer for squeezelite setup, there was about 5+GB shown as free, so i set up the buffers with 2G each. then, even though both LMS and squeezelite were nominally working fine, LMS was unable to find the squeezelite client. when i changed the buffers to 1G each, LMS could see the squeezelite and, voila, music happened.

Funny, I have had a NUC running in my car. The center console has a container with 12 volt and USB power along with analog RCA inputs into the factory head-end. With a IFI Black label DAC, SDcard storage, and Roon remote on the phone all is good. SQ is crazy good. Costs of second Roon license sucks. Pareto Audio aka nuckleheadaudio Link to comment

Costs of second Roon license sucks. interesting........i hadn't thought of running a nuc with 12v in the car........may have to play with that too! (and compare it to the RPi) i've had a few versions over the years, including a first gen RPi, then an odroid based system, even a logitech touch based car music server, all with with GeekOut external dac. i've also had a few of those self contained wifi/hdd music players from seagate. i currently have a fiio m7, that is for use with air/train travel (not likely soon), as my current source to aux in of the car system. i've also used the fiio m7 to stream from 4TB western digital passport wireless pro (hdd + wifi) but that is sometimes iffy for some reason. i'd like to keep wifi out of this setup if possible. i plan to give the RPi a fixed IP address, and use squeezer app on an old android phone (fixed iP) with a usb<==>ethernet adapter to connect the two directly. by the way, i totally bypass my car's factory head-end and use the aux input on a mosconi controller. the high level audio output of the head-end unit also feeds into the mosconi so i can use built in radio, apps, etc. the mosconi is a great solution for getting great sound in the car without disabling or interfering with the head-end unit in the dash.

cat6man Posted December 12, 2020 Share Posted December 12, 2020 update: i'm going to put this on hold and see about using a nuc wth audio-linux in the car, which should bring enough horsepower and ram to eliminate the bottlenecks i've been seeing with the RPi. the RPi will be put aside and brought out for some other project next year. so the new issue will be supplying 12v to both a nuc and a 6-8TB hdd. Link to comment
cat6man Posted December 12, 2020 Share Posted December 12, 2020 and just to clarify, the RPi bottleneck is running the combination of LMS + squeezelite + large squeezelite buffers. RPi/audiolinux seemed to work fine without large buffers, but in my NUC home based system the large buffers offer a substantial boost in SQ Link to comment

AudioDoctor Posted January 9, 2021 Share Posted January 9, 2021 I have an Audiolinux question and I hope one of you has the answer. I have been trying to find verification on the website and have not been able to. Does the Audiolinux Raspberry Pi4 image have NAA functionality? No electron left behind. Link to comment
hifi25nl Posted January 10, 2021 Share Posted January 10, 2021 Yes, raspberry pi4 version has NAA, Roonbridge, Squeezelite and Shairport-sync (open source equivalent of AirPlay) already installed.

al2813 Posted January 16, 2021 Share Posted January 16, 2021 I recently have gone through some HW testing and finally when over, I am now concentrating on optimizing my AL installation. Am far from being super comfortable with Linux, but have been getting a bit better (and many thanks for the patience of Piero who answered all questions even when errors appeared due to silly mistakes made by me 🙂). My AL server runs Roon core and is also an end point. It is running in Ramroot as this is, at least in my case, bringing a massive improvement in SQ. I know that some people here have been doing much more tweaking to the config, and would like to attempt some tweaks in expert mode if other users can share what worked best for them? Link to comment
Popular Post Crom Posted January 25, 2021 Popular Post Share Posted January 25, 2021 I just wanted to thank Piero for some great support that I received, last week and over the weekend, whilst trying to update my systems recently (I've been too busy this past year). I bought unlimited upgrades to the various versions of audiolinux I use a while back and his availability to his customers is quite amazing - thank you! Incidentally, if anyone hasn't upgraded to the latest version of headless AL then I can report it is well worth doing. Best, Crom lmitche and Oscarhuge 1 1 Link to comment
