ESP32 – Bodmer TFT_espi / autoconnect github / Picoreplayer 4.1.0 / Dietpi V6.18

so, 😉
nothing particular new; „audio“-wise its a little bit on „hold“ (had first to buy some +-15V toroidal transformer and so on) but i made a little progress/effort „usability-wise“..
i´m now able to get something in the spiffs-fs (ESP32), read it out 😉 and display it via „drawJpeg“ from the famous Bodmer TFT-eSPI-library->Link

(!! sorry for the still absolutely „shitty“ layout, but i was only happy to get something on the display at all 😉 !! (will change/edit it then; only some „ideas“ (for not doing it in this way 😉 ) for u maybe)
was a little bit difficult because u (i) really need the absolutely newest libraries (jpegdecoder.h for example too) from the bodmer-github-repository (some older example jpgs are unreadable by their own decoder-library and so on..)..
have still some problems/the first third of a decoded jpeg is corrupt, but i can now upload some jpegs in the spiffs, list and display them..(and understood how)
the whole sketch (web-gui for filter-selection, HW-volume control via digi-poti, display jpgs etc..) is here->Link and i maybe make a post in the forum->Link..(could be very interesting for some who also want to understand the ESP32 „better“)..


by that it was all build on top of the absolutely fabulous „Autoconnect-library“ by Hieromon -> https://github.com/Hieromon/AutoConnect; absolutely super great webserver/wlan access library->absolutely to recommend !!
Picoreplayer is now at V4.1.0 (24.Nov 2018)->https://www.picoreplayer.org/main_downloads.shtml(Pi-Kernel-bump to 4.14.81, squeezelite-update, support for Rpi 3B+ and so on->Link
Dietpi is now also at V6.18 (26/11/18)(some bugfixes+improvements)->https://github.com/Fourdee/DietPi/blob/master/CHANGELOG.txt
that was it for now, more to come, stay tuned, greets 😉

The OPA627AU arrived – very „warm“- not so much „digital-room/-soundstage“/ Volumio now at V2.502 / dimdim.gr

so 😉 ,
finally the OPA627AU (as dual on one DIP-8) arrived..
and indeed, absolutely more „analogue/tube-sound“ (in comparison to the AD797ANZ + LME47910-20s) here..
very „warm“, but with a lot of „body“, more „natural“, not so digitally „harsh“ as the AD797ANZ (or the LME47910 of course) by example..


better for high-volumes->thought first „more right/true“->more hi-fi..(but also maybe a little bit „fatiguing/boring“ due to the analogue „timbre“)
not so much „digitally room/3D“ what i liked the most on the ES Sabre-Chips; very „sweet“..
The OPA627AU and the AD797ANZ are absolutely on a very similar „level“; u absolutely dont go wrong in using the OPA627AU..
but for me, i think i stuck with the AD797ANZ; more „room/clinical“, but thats really an absolutely personal impression/affection/taste..)
i think the speciality on these Sabre-Chips is this digitally room/3D-feeling + also with the great soundstage..
so i stay, as said, with the AD797ANZ (all on this „Blue“ ES9038Q2M; the „Green“ have a slightly different characteristic as mentioned in an earlier post..)
(Update 2hrs later: i will definitively stuck with the AD797ANZ; for me absolutely the better choice !!)

by that Volumio is now at V2.502, some minor bugfixes + Pi Kernel-bump to 4.14.71; couldnt determine any differences in the overall tune..


by that i want to suggest/introduce you to http://www.dimdim.gr again..
absolutely great site; inventor of the famous „Hifiduino-project“; a lot of very interesting infos/tips there; take a look over there !!


more to come !! 😉

New Moode V4.3 out – now as an image (.img) / ESP32S factory-reset/flash

so, 😉
a new „Moode“ V4.3 is out; now as an image (.img); u dont have to set it up/compile it for yourself anymore->Moodeaudio.org
first impressions: (all in relation to „our“ ES9038Q2M-„chinese-boards“):

choose first the „I2S-generic“-settings; runs okay, no problems..

used then the „Audiophonics ES9028Q2M“ setting->for me better, not so „harsh“, got the feel it has more room, more „exact“, think its maybe about the specialized register-adressing of the ESS-chips (but don´t know for sure if they „fine-tune“ it for the chip, guess so)…used then to cross-check the „hifiberry-dac“ settings; the same there; for me absolutely to „harsh“, too much treble (not such a „fine resolution“ as the AudiophonicsES9028-setting..)
(the „Allo Katana“-setting (at contrary to Volumio) works also NOT !! (on the ES9038Q2M (chinese)))

stayed with the ES9028Q2M-setting, then tested for DSD(DoP): works, Moode said „Encoded to DoP 352.800khz“, but the DSD-Led on the ES9038Q2M was NOT lit !!

disabled the software-mixer, resampling-options, but still no DSD-light..

i´ve mentioned it in this post/article before-> http://essabre-90xx-rpi.sfb2.com/2018/09/volumio-now-at-v2-452-did-it-dsd-lock-light-on-es9038q2m-alsamixer-archphile-xmos-usb-audio-etc/

the first time i´ve got the feel of real DSD/DoP (and the DSD-Led was lit of course) was in/with „Volumio“; foobar2000 also said ASIO-active (pcm-mode) 352.800khz and so on, but the DSD-Led was also not lit !!

conclusion for now (for „our“ lovely chinese-ES9038Q2Ms 😉 ):

true/real DSD/DoP (DSD-Led lit) only on Volumio (V2.452 and up) (and meanwhile i think thats the point: with the „Allo Katana“-settings !!so far !!

by that, in listening here Moode is very very close to Volumio (maybe a little better at present IMO) (but as said, this is an absolutely personal/subjective impression).

also my ESP32S Geekcreit (Doit.am 36 pin) was not functional anymore, couldnt run/upload a sketch, tried everything, found now a way (and mainly with the right hex-adresses for the espressif-flashtool) to made it functional again->long Tut here (at the forum/at the end of the post)->LINK

greets for now 😉

Volumio at V2.457 / Dietpi V.6.16 / mympd / upgraded ES9038Q2M decoder board I2S

so, 😉
after searching today for some new ES9038Q2M-boards/-infos, i´ve found also this „Upgraded version of ES9038Q2M decoder board I2S input OPA1612+AD8397ADRZ“ (it was also mentioned in these diyaudio.com-forum)->Link

it costs only about 42$ (incl.shipping), and interesting is (besides all the disadvantages like the 5V-9Vplug, the only-headphone 3,5mm jack and so on) that they use „OPA1612“ for the AVCC-section and some „AD8397ADRZ“ for the „output“-section..

i´ve googled immediately for „AD8397ADRZ“ and according to this post/article->https://www.head-fi.org/threads/audio-gd-discrete-op-amps-reviewed-opa-earth-opa-moon-opa-sun-v-2.397691/ its only in the „Category 2 – nice but incomplete sound“ 😉  (posted the link+excerpts also in the forum here->Link)

the author there also said, that for him (and thats interesting for me) the AD797BRZ (i have the AD797ANZ here) are the only ones in the „Category 5 – complete sound traveling in the clean air“ 
„..roughly, it’s like the AD79ANZ with all advantages of the OPA627BP added“ and as u know, i just wanted to buy lately an OPA627 (the „Bugatti Veyron“ on the OP-Amps) to „finalize“ my op-amp-experiences..
so i guess i have to check-out these AD797BRZ some time too 😉

another thing is that they are now at Volumio V2.457 (PI Kernel bump to 4.14.69 and some fixes), i´ve tested it immediately with the ES9038Q2M and the „Allo-Katana“-setting, and it was, as said in an earlier post, „massive“ (ES9038Q2M+2*AD797) again !!

 

this time had the chance to test it before with the ES9028Q2M-option (in Volumio) and some minutes before also with the i-sabre-k2m option in Dietpi V6.16..

last time i thought it could also be by the changed footprint/pi-kernel-bump but today i would say the „Allo Katana“-overlay is more specialized on the ES9038Q2M-core->

finally, at present, i must really say that i have the best sound (on all distros) with the newer Volumio (V2.452 and up) + „Allo Katana“-settings on an ES9038Q2M+2*AD797 !! (okay, its really tight between them but Volumio is absolutely easy to handle at present)

DietPi is now at V6.16, i just wanted to set up the new „mympd“-(fork of ympd), ran into trouble, theres a workaround now and its fixed in DietPi V6.17..(„Allo Katana“ works NOT on DietPi (with the ES9038Q2M) but with the „i-sabre-k2m“ overlay i got 32/384..)

more to come, greets for now 😉

 

Volumio (now at V2.452) did it->DSD/Lock light on ES9038Q2M / Alsamixer Archphile XMOS USB Audio etc..

so, 😉
after i tested „Archphile“ with the Skysong-Xmos-USB-interface and still don´t know to limit the DSD-rate to the DAC/-combo (it uses 705600 but the ES9038Q2M doesnt support it, i got only a heavy white noise), tried everything in the /etc/mpd.conf; i used again „Volumio“ as it said in one of their forums something about their DSD-native/DoP-compatibilty..
so let it run and hooray, the DSD-Led on the ES9038Q2M + the DSD-indication on the skysong-bridge were lit !!

(hadn´t got the DSD-indication before afaik).

wonderful, true DSD/DoP-sound !! 😉

had used foobar2000 with the Asio-driver/DSD-processor, the singxer audio-panel said:“Asio active(PCM-mode)-352800khz sample-rate“, see 2 posts before, but meanwhile i think it was converted !! to PCM- (with soxr by example) >because i hadnt got the DSD-led on and it wasnt not such a great improvement to „normal“ PCM..
now with volumio it sounds absolutely fantastic, absolutely real DSD-„sound“ !! („real“ DoP)

by that i´ve think meanwhile „Archphile“ is for the really high-end USB-DACS->384khz,768KHz (and above); think its about the „Arch-linux ARM“-kernel/core..
also u got a wonderful „Alsamixer-volume and master-clock“-mixer for the XMOS-USB-audio interface (with the command „alsamixer“)->

also interesting in Volumio is that if use the „resample-option“ in the settings it affects also the „DoP-chain“->set at 384khz resample/sox/very high, got my red light (PCM) on the bridge on and no DSD-light on the ES9038Q2M..
interesting II. is that u can resample up to 768khz (in Volumio) and u can hear something (but heavy white-noised) on the ES9038Q2M although somebody posted it can only play/(is capable of) up to 384khz in „asynchron-mode“; but i heard here something..->


greets for and more to come !! 😉

„Archphile 0.99.73 Alpha“ + XMOS USB-Bridge (Skysong)->768 khz !!..

so, 😉
in trying to play finally some real/Native DSD on some (our „lovely“ 😉 ) chinese ES-Sabre-boards i came by chance about the „Archphile“-distro->https://archphile.org/ (knew about it , but hadnt got the time to test it till now)

it uses mainly the mpd-subsystem and i´ve read some days ago that it also could be a driver problem/xmos-usb-driver thing on linux to get DSD-native to work..!!
so and today after imaging the archphile-archive, and first i must say its really hard/difficult to „understand this archphile-distro“, because u got only a MPD-user interface with almost no settings (for the DAC for example and so on), u have absolutely to work over SSH in first place..
so but the really interesting thing is this->
first picture is the output of the „alsacap“-command (its Arch-linux)->
absolutely super fantastic !!! it says that the XMOS-USB-device (Skysong) can handle up to 768khz (via linux usb-driver)!!!

(a problem could (may) be that it didn´t show the „DSD_U32_BE“ sample-format which is normally a clear point/-„ means that this DAC supports Native DSD in Linux.)
but anyway absolutely fabulous !!
and much more fantastic is that it sends 705600 !! to the xmos-usb !!!->(with the „perfcheck“-command)

by that, „Archphile“ has a very good/clean sound; sounds better than the picoreplayer for example (IMO), really,really clear !!

but got a really „destroyed/white noise“-tune with these 705600 on the ES9018K2M(and didn´t find a way here right now to lower it down to 352000 for example); have it really hard  to work it out here at present; (the ES9018K2M has lower capabilities DSD-wise than the ES9028Q2M or the ES9038Q2M for example).

flacs (all up to 24/192) are playing very,very well..but anyway as said, really,really great news !!

more to come !! -> greets for now !! 😉

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->https://www.picoreplayer.org

its almost the same; like in this phenomenal 😉 , earlier post-> http://essabre-90xx-rpi.sfb2.com/2018/04/new-picoreplayer-is-out-v3-5-24-march-2018/

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..

second:

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 😉
