By the for those interrested, I have a Raspberry Pi running Squeezelite Headless;, I'll report if it is working as soon as i get the board and the time to setup with a DAC (TDA 1543)
I have tried recently the Naim Dac-V1 on the Rasberry Pi (it uses Audiophilleo usb-spdif or i2s oem) and it worked like a charm but I only tested 16/44k1Hz materials.
Did you get your board and tested RPi with Amanero?

I'm interested if it can stream flawlessly/without cracks 384K FLAC.
Thx. Zsolt

no way, its not afaik UAC2 compliant, i'd be happy to be wrong about that, but that certainly has been the case.

It seems to be UAC2 compliant as it plays 192Khz.

From RaspberryPi piCoPlayer thread - link :
"Audiophileo ok upto 192KHz
Naim DAC-V1 (Audiophileo USB Asynchronous) ok upto 192KHz perfect sound quality
Amanero (Asynchronous USB) ok upto 192KHz

As Wifi, I use a TPLink Nano Router TL-WR702N USB Powered, perfect.
As DAC I'm currently use a twicked Teradak that is very good in SPDIF but not in par with the Naim DAC-V1 in USB."

well thats new, havent checked the Pi forums for about a month, as i'm more interested in beaglebone black, as hires USB audio has in general been unreliable on pi since release. I became disinterested some time ago.

from the link its clear thats with a custom coreplayer linux build as well aka piCorePlayer, that works with squeeze player/server

so i'm not sure you can say its UAC2 compliant, UAC2 can do up to 32bit/384khz multichannel

Regardless of what your idéas are Mr."qusp" - both DSD and 384k/32bit works with linux and OS X, also volume control (ES9018 internal) works from linux and OS X apps...

regardless of what your thoughts are..RayDreamDichotomy, I said nothing about linux limitations, rather the currently available rasberry pi hardware and pi linux builds.

gotta love your consistent communication problems, very good for causing conflict though... best read properly next time if you want to come off less of a (edited, insert your own word)

that being said, it seems at least with the build linked above that the Amanero is working up to 192khz PCM on pi (DSD?), which is excellent, but its certainly not enough to interest me in the pi. playing 2 channel 192khz PCM under some circumstances doesnt make it UAC2 compliant, to be UAC2 compliant it should comply with the spec, which is multichannel up to 384khz.

a brief search just now confirms consistent/persistent problems with the USB driver causing glitches and crashing; with no reports posted of multichannel UAC2 devices working that I have found. the pi spec and linux capability reads like it should work, but nobody has mentioned making it work yet and the fact the ethernet and USB share resources rules it out for me anyway.

the USB driver does not seem very robust for higher bandwidth operations and certainly is very limited for power (not such a concern if you are powering separately)

I didn't asked whether it's UAC2 compliant or not, I simply asked if it can stream stereo 32/384Khz through Amanero.
According to tests (link) USB can do 30MB/sec and ethernet ~50Mbps. The later is slow and will probably not live up to expectations but that's the question to be answered. I might get a Pi from a colleague next week and can answer this.

A wiki for amanero would be great, or a help page with all the tweak;
I want to feed the card with an external power supply,this procedure is good

and what are the supply voltages?
