New Picoreplayer is out->V3.5 (24.March 2018)

hi there, 😉
a new picoreplayer is out->V3.5->https://sites.google.com/site/picoreplayer/home/news

new rpi-kernel/firmware, „..Updated to Squeezelite 1.8.7-1052, includes native DSD support.“, got it to work (ES9028Q2M) with the „I-Sabre-9023“ „card-control“, checked „384k“, Logitech Media Server is now at: V7.91->http://downloads.slimdevices.com/nightly/?ver=7.9
(nevertheless u have to activate the DSD-plugin under „plugins“))

sounds very „strong“, good, low latencies (thx to the new rpi-kernel+firmware and so on), got DoP with 352k and without any commandline-options like „-e dsd“ or „native DSD-patch“ and 384k PCM with „X“ (command-line-option)..

 

very „fast“ (low latencies) as said->absolutely the advantage of a very slim/less resources using system; no disruptive layer/driver..
(but as said, still with a little bit „metallic“-sound; don´t know why..)

ES-SABRE FORUM (Update) + HC-06 BT Rename + Dietpi 6.4 (+ES9028Q2M)

so, 😉
sorry, i´ve just seen that it was impossible for unregistered user/guests to see any content in the forum->forget to uncheck „Force Guests to register/login to access the full content„(it was, as i hardly remember, because of the f***** spam-attacks); its solved now..->FORUM
second i´ve made a new post how to change the „identifier/baudrate/pin“ of a HC-06-BT-module->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=34
third i´ve updated to „DietPi 6.4„->http://dietpi.com/ and it plays here soo very well with my „ES9028Q2M“->absolute wonderful..(just connected 2 DIP-buttons via a breadboard to the 8 pin HW-control on it..); soo nice..(i will also try in future to solve/control it via some BT/Arduino-control)
fourth i´ve installed/set up a „search„-widget in the upper right..thought it was already there but wasn´t 😉


Audio-Distros: Dietpi decided to revert to RPI-stock kernel..(very sad)

so, 😉
its very,very sad, but „Fourdee“ over at DietPi decided to go back to RPI-stock-kernel means no more enhancements/improvements in 384khz-playback in Linux/RPI-kernels (for our lovely chinese ES90xx-Boards via I2S) ;-(

thats really,really sad because in the earlier Versions of Dietpi (i guess till V1.54) it was the only RPI-audio-distro which sounds really good (Best !!) with at that time the ES9023 (dtoverlay=hifiberry-dac)+ES9018K2M at 384khz with no prob played via MPD..
u could change the sample-frequency via their wonderful „Dietpi-Boom“-Gui..;-(

Text on the Github-Page->Link:
„I’ve taken the decision to revert our DietPi RPi kernel to stock RPi kernel.
Currently the only difference in our kernel was:
DSD pop prevention on initial playback.
We simply do not have the man power and available time, to ensure this is updated regularly with requested patches. Time we can use to focus on supporting bug fixes and improvements for DietPi.
In future, all RPi kernel patch requests should be made directly to the RPi foundation, who have paid employees dedicated to that specific task:
https://github.com/raspberrypi/linux
This will ensure all RPi users will benefit from the requested fix, if accepted by the kernel maintainers.
I apologise if this effects audiophile users, however, I hope we have your understanding for this change.“

so, we have to look now for alternatives, cause as said DietPi has for me the best „sound“ of all (audio-)-distros for the RPI (guess it was because of the lightweight-design (less processes,less distortion))

1. Moode ->Link… now at V4.0Beta12..has also canceled their RT-/advanced-kernel thingy..(all concerning the support of our lovely chinese ES9023,ES9018K2M,ES9028Q2M and ES9038Q2M-boards via I2S)->hope they will invent it again..
2. Volumio ->Link (now at V2.348)… found it really horrible at the beginning but meanwhile its much better..absolute easy to use; almost no pops,clicks, and a very relaxed/easy use (try it again 😉 ) but now also not with full 384khz support for our boards via I2S..
3. Picoreplayer ->Link.. now at pCP3.22 (27.Sep.2017)->absolute 384khz-capable (look at the other posts), but not so comfortable..

these 3 were my choice after i tested a lot of other audio-distros for the RPI at the beginnung with our ES-Sabre-Boards(there were a lot more, Daphne, Rasp-something, Runeaudio etc..but the above were the best/most comfortable imo)

if u mean u know another good audio-distro (comfortable, easy to use, 384khz) please leave a comment here !! (and we can move it maybe to the forum->http://essabre-90xx-rpi.sfb2.com/forum/)

ES9028Q2M+ Volumio 2.323 (17.11.2017) + Hints about 384khz in general

so,
i normally „hate“ this Volumio->came back to it by chance..


(V-2.323)
https://volumio.org/get-started/
so, very smooth and clean..not so many pops,clicks and noise..relaxed..->try it !! 😉 (i wondered myself->relatively good alternative to the other rpi-audioplayer at present)

I used „Generic I2S DAC“ and then came „Hifiberry-DAC“ automatically..
tried to upsample it to 384khz but was not possible „ALSA-error“->and so we are back to the main problem with 384khz and this ES9028Q2M-Board (tried to recall it here, before i forgot it again):
Over I2S and the RPI3B its normally only up to 192khz->for more (384khz) u need a kernel patch..
In picoreplayer u can use the „es9023“ overlay and the the „384khz“-option then (as said some articles before); but picoreplayer is not so comfortable..
same at present with MoodeV4B9 and „hifiberry-dac“->because it has not now the advanced and realtime-kernel as before also no 384khz: same at present with Dietpi..
DoP seems possible; and so we come to the next article->DSD-LED (+Volume and FIR-Buttons) on these ES9028Q2M->http://essabre-90xx-rpi.sfb2.com/2017/11/dsd-led-volume-and-fir-buttons-on-these-es9028q2m-boards-diy/

Audio-Distros: DietPi + MoodeV4Beta9 (automated install-script)

so,
Fourdee over at Dietpi->https://github.com/Fourdee/DietPi made a script for an automated DietPi + MoodeAudioV4B9 install..
works here (RPI3B + I2S-ES9028Q2M) fabulous and with absolut no issues (install/compile about 35-45min)..
„Skript“/infos are here->https://github.com/Fourdee/DietPi/issues/1223

„Currently in testing, under RPi Stretch.
Steps to test the DietPi + moOde installation:

Download the DietPi Stretch image and write to SD card: http://dietpi.com/downloads/testing/DietPi_RPi-armv6-(Stretch).7z
Download the following automated installation file http://dietpi.com/downloads/conf/moode/dietpi.txt and save it to the SD card /boot/dietpi.txt. This will automatically install moOde on 1st run.
Connect Ethernet.
Connect HDMI if you want to see the installation process.
Eject SD card, pop into RPi and power on“

(PS.: its then „dietpi/“ in the browser-line and not „moode/“ and the ssh-login data is: user=root and pass= dietpi)

UPDATE: MoodeAudio V4 Beta9 + ES9028Q2M (chinese-board) (DoP)

okay,
got here after a few updates Beta9 to work..
tried a lot, but with at present only „Generic 2 I2S-hifiberry-dac“ settings available and without the advanced or realtime-kernel i got only max 192khz over the bus..(with this ES9028Q2M)
so i fiddled a lit bit around with the DSD-settings, and it was only „DoP“-possible (see pictures) (not native DSD !! afaik – but have no problem with that here) with this board + actual settings but u have to set „Sox resampling=enabled“ and „DoP=yes“..curiously with sox resampling disabled-> no DoP !! (just for info)
DoP -> „yes“:

(DoP „no“->then no native DSD also->only PCM):

(rem.: it displays „DSD“ anyway->its related to the file (extension)) 

(Update: Moode V4 Beta9 as 2.6GB compressed to 920MB image here->Link (Google-Drive))

MoodeAudio **FREE** !! (FOSS-license) Version 4 Beta 6 – RPI-3 (+ES9028Q2M)

absolute fabulous !!

Moode-Audio Ver.4 Beta 6 is now available via:
http://www.moodeaudio.org !!
problem is u have to compile/set it up more or less by yourself..
U only get some moode-audio-files (.zip) but has also to download debian-stretch-lite and make/bring it via a lot !! of shell-commands to work..
For me it took about 4 !! hours..
so for this reason, i decided it to upload the SD-Card-Image (about 2.5GB) to „Google-Drive“ (for other, not so „Linux-Enthusiasts“ 😉 )->use „Win32DiskImager“ or similar to write it to SD-Card..but be careful its under the GNU GPL-free license !!
Debian-Stretch-Lite->LINK (orig. Raspberry.org)
MoodeV4.0Beta6-files(+recipe)->LINK
(Update: thx to someone over at the MoodePlayer-Forum Link here is an Image of Beta9 at Google-Drive-> (2.4GB compressed to 918MB)-> Link (Google-Drive)
(rem.:this is the so called „BASIC/no extras“-Installation, without wiringpi,rotary-thing and without additional components (u can install them then by yourself)
so, Settings for the ES9028Q2M (for now):
got only „RPI-Dac“ to work; but limited to 192khz as said..“Hifiberry-DAC“ only works with mp3/: ->flacs->horrible noise..(if in 16bit->try to set min. 24bit in „MPD-Settings“)
try to check more options->post it then here..
Installed squeezelite too, and for the first time, NO loud clicks by switching from 16/44 flac par example to 24/96 or 24/192..
