How is the Pi 4?

Thanks for sharing. I have tried this version - I actually am unable to connect to the PCP web GUI or ssh into it (although I do see the IP appear on my network). Do you happen to know why there are issues getting into the web GUI/sshing in?

Someone also experienced a similar a problem, then the author recommended trying another SD card instead of USB drive here

He mentioned that Raspberry Pi 4 might be somewhat picky about USB storage devices due to different CPU frequencies / voltages etc. As a result, not everything would work partially if specific components of piCorePlayer were becoming dysfunctional.

After trying sd card instead  of usb drive  still could not able to boot up?  i wonder  why?

The author posted another update several hours ago, basically he's able to ping the IP address successfully but somehow it ain't getting any further afterwards. Then he simply tried a better USB drive and that did the trick.

 

Not sure why that's happening, I guess that maybe the read speed of USB drives could make a difference if we're running the CPU at a specific frequency for the sake of achieving better SQ. The author said that editing the file config.txt could solve the problem if the vaule of the line arm_freq were changed to this

 

https://docs.picoreplayer.org/how-to/edit_config_txt/

arm_freq=1600

 

Though it's supposed to be detrimental to the SQ according to the author.

Next generation low latency & low noise ASM3142 USB 3.1 host controller generates a clear USB Audio datastream.

 

In general, hardware support really depends on the kernel of whatever Linux distro we're running.

 

More specifically, the latest releases seemed to include support for USB cards with ASM1142 / ASM2142 / ASM3142 etc.

 

https://github.com/torvalds/linux/blob/master/drivers/usb/host/xhci-pci.c

https://github.com/raspberrypi/linux/blob/rpi-5.4.y/drivers/usb/host/xhci-pci.c

https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/usb/host/xhci-pci.c

 

Maybe take a look at the list of USB cards here? Though all of them looked more like 5Gbps (Gen 1) cards instead of ASM3142 @ 10Gbps (Gen 2)

Hello! Yes I saw these links. I’m just wondering if I use Volumio or Moode (and I don’t know if they are Linux based), if I use the new Pi 4 module with the PCIe and a JCAT USB XE (powered by its own LPSU), would it be recognized like an Allo USB bridge HAT would? If yes that would be incredible.! I’m looking right now online but can’t seem to find an answer...

Thanksgiving Edition with further SQ improvements

Noël Edition with the best SQ in 2020 so far

CPU will be overclocked to 2.205 GHz by default, Raspberry Pi 4 Rev 1.2 or above is required and adequate cooling is essential for achieving positive results

Another requirement for booting off USB drive is adequate reading speed in order to ensure that OS could start successfully.

 

Someone already compared Noël Edition to previous releases, the latest one seemed to be the champion

Merry Christmas to everyone and please stay safe.

Downloaded the files. put them together with 7zip, flashed the SD card.... it does not boot on my pi4...

"flashed the SD card" - I assume you mean: extacted it and wrote it to the card with something like Win32 Disk Imager  or Etcher that writes images to the card?

 

Main listening (small home office):

Main setup: Surge protector +_iFi  AC iPurifiers >Isol-8 Mini sub Axis Power Conditioning+Isolation>QuietPC Low Noise Server>Roon (Audiolense DRC)>Stack Audio Link II>Kii Control>Kii Three >GIK Room Treatments.

Secondary Listening: Server with Audiolense RC>RPi4 or analog>Matrix Element i Streamer/DAC (XLR)+Schiit Freya>Kii Three .

Bedroom: SBTouch to Cambridge Soundworks Desktop Setup.
Living Room/Kitchen: RPi 3B+ running RoPieee to a pair of Morel Hogtalare. 

All absolute statements about audio are false :)

Thank you so much! This is truly amazing and sounds so good.

 

What specific settings did you use on the Squeezelite page of piCorePlayer?

I use a DAC/Amp on the USB output of my Pi4 (8GB) and i am not sure what settings are the best in terms of ALSA buffer and so on. I would really appreciate your help :-)

Overall the NOEL piCorePlayer Version in combination with the Squeezelite version by soundcheck sounds absolutely amazing. I've overclocked the CPU to 2.2 GHz as well with no serious problems as long as you got a good case for the pi. I a passive case from Miuzei:

This setup can easily compared to a lot more expensive streaming solutions.

 

I also made some good experience with USB reclockers like the Oehlbach XXL MasterClock or the UpTone USB Regen. I personally use the Oehlbach MasterClock:

And very important is a good power solution. For the Pi and the MasterClock i use TeraDak DC 30 PowerSupplies:

Overall not the cheapest solution but it sounds so damn good!

Thanks for the interesting feedback! I briefly tested the November release and couldn't get the Noel one working. I discovered the reason I think. The Pi I was using was a revision 1.1. I do have a second Pi and this one is 1.2 so can try and get this to work. couple of questions:

 

- Were you actually able to compare your setup with a properly setup X86 system?

- You have two Teradak DC 30? one for the pi and one for the reclocker?

Correct - i have one TeraDak DC 30 with 5V for the Pi and one TeraDak DC30 7V for the USB Reclocker.

 

I can only compare it to my X86 Desktop-Setup with Audirvana and my "old" Allo USBridge. And the Pi combo definately sounds better than both of them.
