New Picoreplayer is out->V4.0.0 beta 5 + Moode 4.2 install instructions („moslog“)

hi there, 😉
a new picoreplayer is out->V4.0.0 beta 5->

its almost the same; like in this phenomenal 😉 , earlier post->

this time they have a rpi-kernel bump to Kernel 4.14.56, the DSD(Dop-)-„native patches“ are included, selectable..

tried to use the new „Allo Katana“-overlay here too on an ES9038Q2M->no success/didnt work/squeezelite refuses to start..

use now again (as described in the mentioned, earlier post) the „i-sabre-9023„-overlay, checked „384k“ and „bclk_ratio_int_div“ option, under „Card Control“..

got 32/384 without any problems, same with DSD-„material“->up to 32/352..(see also earlier post)..

but still a little bit „metallic“-sound; as described and still don´t know why..

Volumio“ for example has for my ears (IMO) a far far better sound/tune..


a few days ago, i tried to install Moode 4.2 on a fresh raspian-stretch-lite..i knew there were such commands like „mosbrief,moslog and moslast“ for monitoring the installation progress; but i didn´t know how to use it correctly..

started the installation anyway, but as you see absolutely nothing !! u don´t know if it hangs/or is finished or something and so i had an incomplete installation after all..

so today i had the time to re-test it; in short: place a „ssh“-file in the root of the card (after imaging the raspbian stretch-lite on it); u can now ssh on it..make the commands for the mosbuilding (absolutely fabulous !! article about it in english here->Link and in german here->Link (fabulous !!)

after rebooting the first time (u first have to make a „hard-reset“, means unplug and re-plug the power (else it didnt work !!) u can now ssh on the pi again (while still working/compiling etc..) with now (and thats important too) ssh-login: pi and pass (thats new): moodeaudio

now u can type „moslog“ and can watch the installation progress, wonderfulst !! 😉


by that i´ve „demolished“ my lovely raspberry zero w ;-( , wrong soldered and so on (but this „soldering“ was, as said, more difficult than on an arduino or esp32-board for example)..

i still want to buy a new ES9038Q2M Green V1.07 and finally some OPA627, but have a small „cash-flow“-problem, „distinguished said“ at present 😉

will post then maybe more again 😉

Volumio v2.444 out / „Allo Katana“-support -> works on „chinese“-ES9038Q2M too !! / massive.. ;-)

so, 😉
a new Volumio is out->V2.444 ; its here->
changelog says: „..Pi kernel bump to 4.14.56, Allo Katana support etc.“..
tested it here rightaway with the ES9038Q2M (2*AD797)->“massive“ 😉

but back to the Katana-overlay: at first „hear-out“ i´ve got the feel its more „massive“, more „accentuated“ (especially with the 2*AD797)..
don´t know at present if its the Katana-option, or the optimized Volumio-„footprint/improvements“ (see changelog)..
unfortunately i´ve got only 192khz/24bit with „audio resampling on“ (set it up for 384khz but got only 192/24)->

by that, there´s also a new „Volumio ESS9028QM„-option; works too (with the „Blue“ ES9038Q2M) (but didnt test if it reaches 384khz)..
but anyway there´s absolutely an improvement „sound-wise“ again !! „sounds“ again more „right“; really heavy, absolutely to recommend !! (RPI 3B-ES9038Q2M-2*AD797)

by that i´ve experimented a little bit more with „node-red“ and now with „MQTT-broker,-subscribe+publish“ and so on; really freaky, u can seamlessly connect an android app (->picture) with a pi zero as mqtt-broker and then via bluetooth (or websockets) to an arduino or said absolutely „whacky“ 😉

(„IoT MQTT Panel“->google/android-playstore->

(this is as said, all for (in favor) of our lovely „DIY-DAC„-project , display and usability-wise)..
(will post maybe then more..)
but as said, really a sound improvement with the new Volumio (+“Katana“-option)..
greets for now 😉

Raspberry Zero W V1.1 + Volumio / I2S-connection + Dietpi-Update V6.12

so, 😉
its a little bit silent here lately but it doesn´t matter->here some infos about a Raspberry Zero W V1.1..
because they´ve updated the Arduino-ESP32-core here on github->, and my self-made-noob-sketch didnt work since then on my Doit-ESP32S-V1 anymore, i thought also about to use my raspberry zero W V1.1 to control the ES9038Q2M via web or BT (for the I2C-control of the Digipoti MCP4131 for example, or the relais-control for the different-filter-settings and so on..)
for this (on a raspberry) „Node Red“ (a programming language/editor) looks like a very good attempt/ maybe then a little bit more..
anyway first i have to get the zero to work with any of these chinese-ess90xx-boards..
I´ve ordered the zero w without a pre-soldered header and without a „hammer header“; u can get them so at pimoroni for example of about 13,50€ !! (incl.shipping)->
(u can also get there a raspberry zero (without wlan) for 5,05€ !! (+3,50€ shipping)->

but this self-soldering is IMO on this little raspberry a bit more complicated than normal, it was difficult to get an I2S-DAC-board on this to work..
heres again a little picture how to connect the I2S-lines: (the pin-layout on my zero w V1.1 is exactly the same as before (on a RPI3B for example) (because someone said there are different pin-layouts on different zero´s)

so, i have to use Volumio first to check out where the problem was (the soldering 😉 ), and i took the fresh 2.413 (
works absolutely fantastic here now with an ES9028Q2M (+Muses8920); almost no horrible pops+clicks at changing volume/tracks/audio-formats..
I use here now the „hifiberry-dac“ settings; the „RPI-DAC“ settings are working too (but be careful while using the hifiberry-dac settings->u have to set the target-bitrate to „24bit“(audio resampling on); else u get a horrible noise (but this was clear if u have followed this blog/read a little)..

as said, fantastic here now (i´ve originally wanted to use my old ES9023 for this; but got no sound at all (was this soldering problem 😉 )..
and by that u can use the raspberry zero W V1.1 also with a normal usb-cable on a normal usb2.0-port (500mA)..for me here its enough; hadnt to use the original Pi-power supply (2,5A or something)..
also, Dietpi is now at V6.12 and i still want to buy some green ES9038Q2M V1.07 and some OPA627 😉
greets for now 😉

„allo-katana-dac-audio.dtbo“ available now in DietPi V6.10

so, 😉
the „allo-katana-dac-audio.dtbo“ is now available in DietPi V6.10; means u can select „“allo-katana-dac-audio“ in DietPi->DietPi-config->Audio..
i´ve tested it here with a „Blue“ ES9038Q2M->no success/sound..
(i use the „i-sabre-k2m“.dtbo in DietPi->works very well with the ES9038Q2M here.)

was to be expected because (as earlier posted) the .dtbo adresses the mcu on the katana-board and apparently not on our cheap and lovely chinese 9038Q2M-boards..
else nothing particular new, except i really want to test some „OPA627“ (the „Bugatti Veyron“ under the OP-AMPs) and want to buy some new, green ES9038Q2M V1.07 ..
greets from here !! 😉

Moode/Volumio on a raspberry pi vs. Samsung Bluray-player (spdif-coax) Impressions..+SRC4392 (+beta „Project 2“)

hi there, 😉
long time not seen..its a little bit silent here lately but absolutely no worry/problem..
i´have here some Samsung Bluray-Player (BD-H5500); not the worst; only with some spdif-coax output..
some days ago i thought the only, true,real good sound is via some very good CD-transporter/drive/device + directly via spdif into the ES9038Q2M and go 😉 ..
but as i heard today again the ES9038Q2M with the raspberry pi (Model 3B) and some flacs i felt its really a class of its own !!
1-2 level (soundwise) higher !!
(at present btw. i think Volumio (hated it a long time) has a very good sound/tune; a bit better than Moode 4.1 (then picoreplayer and so on)..DietPi (V6.8 now) is still „in the lead“ (IMO) but usability-wise Volumio is great..)
so, back to topic: i really don´t know why the flacs on a pi (and via I2S) had a such great sound/tune in comparison to some „normal“ CD-spdif-combos (IMO)..absolutely don´t know why; but it is (and this is said by really a lot of people in the „Hifi-world“ ;-)..(maybe its because of this delta-sigma-conversion and the „required preliminaries“)..
by that i think meanwhile the spdif-„conversion“ on the ES9038Q2M could be a problem; its not soo high-class/hi-fi as expected..(spdif-receiver-side)
in my praised DIY-audio-forum->, they are looking lately for some „SBC 4392“ asynchron frequency decoder boards for spdif/usb decoding with 144 db !! thd and ultra-low jitter too..

Link (60$-90$)
think absolutely the same here and because only of „hearing“ out the „distortion/jitter“ via the spdif-receive-unit/decoding on the ES9038Q2M..
(so to see u must use such a SRC4392 before your ES9038Q2M and then via I2S in it, bypassing the onboard-spdif..)..
so, by that i definitively want to try out some AD797 in future (have now some Muses8920 in it) and i also want to buy definitively a new, „Green“ ES9038Q2M V1.07 because i still think the „Blue“-ones (have one here) sound really not so hi-fi as they could/expected (we discussed it here a few weeks ago)..

by that i revive my „Project 2“ a little bit; means BT/Web-control for the different-filter+HW-Volume settings on an ES9038Q2M (u can meanwhile buy it as „set/package“ with display and rotary encoder/apple-remote but nevertheless)
this time i used some „Geekcreit ESP32S Devkit-V1„-board (links/first thoughts about also at the forum-> link-FORUM ) (first post)

(ESP32S connected to a PCF8754 via some 5-3.3V logic-level-converter, controlling a 4-port relay and then to the 4 jumper on the ES9038Q2M..HW-volume via some MCP4131 will come hopefully later..)

but as said earlier, i hear almost no differences between the filter settings on these ES9038Q2M, but when, i would prefer JP3+JP6=“linear phase fast roll-off

(as said, here now listening to it with this filter-setting on a pi with Moode 4.1; and so „dry„; absolutely low latencies, perfect (but as said, Volumio/DietPi sound a little bit better (IMO))
many greets for now 😉


ES9038Q2M: interesting facts + ES9038Q2M DAC HAT by „iancanada“..

so, 😉
came by chance about this facts/post in this very interesting forum->
iancanada“ posted:“..ES9018 and ES9028 need the small DoP daughter board (which can be plugged in the IsolatorPi) to convert the DoP stream into DSD. However ES9038Q2M has a built in DoP decoder, so, for ES9038Q2M, the DoP daughter board is not a must.“,
+“ESS9018/28/38 has internal 32bit digital volume control. Much better than any 24bit digital volume control, but still not as good as the analog one on my PASS XP-10. However according to my listening experience, the difference is not that huge.“..

by that his „ES9038Q2M DAC HAT“ looks very fine, neat and „sophisticated“ 😉 ; mail him..😉
(also very interesting other (DIY-Audio) projects there !! ->
