Got today the AK4113 digital receiver to I2S-output/ still at 96khz/24bit..

Kommentar hinterlassen

so, 😉

got today this little “gem”, the mentioned AK4113 Digital Receiver Board + LCD1602 Screen SPDIF Optical/Coaxial/I2S To I2S Converter”(LINK)

thought first i have to solder the pinheader for the LCD1602 by myself; but it was already soldered->

“powered” it by a simple usb to 5V “converter” but all i got at the end was 96khz/24bit via the hdmi-audio-extractor and also via the coax/toslink-output of the Sony BDP-S7200 and the Philips BDP9700/12->

tried all different settings in the system-menus from the both player (auto,bitstream,pcm etc.,etc.)->no success..also via the hdmi-extractor the max was 96/24..

but don´t know if the AK4113 detects (and displays) it accordingly; but the 3 manual settings on the extractor were “pass”,”2ch stereo” and “5.1”..with the “pass” and “2ch stereo” i got only 48/24 max..has to “evaluate” it more..

UPDATE 1: seems like these special 4k-hdmi-switch/audio-extractor only supports audio up to 96/24..so, be careful in choosing the right one !!

another thing was that i wanted originally connect the AK4113 via I2S (to bypass the spdif-conversion) to an ES9038Q2M, but absolutely no “lock”-light..thought about it a lot and i guess (at the moment) the I2S-line (-cables) are too long (ca.30cm)..(read it sometimes ago->”the i2s-line(-cables) has to be short as possible (5-10cm)..”

UPDATE 2: curiously, i´ve got the “lock”-light (and its playing) with the “blue” ES9038Q2M; so, again, there is often a compability-problem with different devices..

greets for now + much more to come.. 😉

“Shame on me”->very nice “Burr Brown” (uargh) implementation on a Philips BDP9700..

Kommentar hinterlassen

so, 😉

“shame on me” 😉 , but got today by chance a “Philips Fidelio” (uargh, hell 😉 ) Blurayplayer BDP9700 “in” and as u know, i HATE this “Burr Brown”-sound, for me its the sound u have to avoid by any chance, its exactly the opposite of this “airy”/”open-sounding” of the later ES-Sabre-chips, i must say its the finest implementation of any Burr Brown-“gear” i´ve ever had (okay, this thing/player costs originally above 500€ !!)..

but so “honor where honor is due“->very nice “craftsmanship” (and thats the point by the later “Burr Brown”-implementations)..

the “sound” is absolutely superb (FLACs till 24/192 over “internal” stage/chinch), best BB i´ve ever had (as said), rock-solid, but misses these unbelievable ES-Sabre-advanced-bitstream-thing (the fabulous/enormous “soundstage”/”positioning”/”airy attitude”)..

but as u see (they used for example 2 toroidal transformer (one just for audio)) its absolutely made on a highest level of “craftsmanship” and so u got a result which has also to be achieved..

picture-wise these player is worser than the other Sony BDP-S7200 which i also have here; by that the firmware is too old + buggy->the Sony (and the newer Sony UBP 4K-Player) are absolutely better IMO..

(these have btw. and as u surely know 2 x HDMI-out (1x for audio only) (absolutely “common usage” nowadays)..(these Philips has also 2 x HDMI but u cant get DSD (via DLNA) over HDMI out)..

so, clear and rock-solid BB-sound here now (but not for long !!), in this sense, greets for now, more to come (especially about this HDMI->I2S-thing) !! 😉

SFB2

(eventually) “Lock”-problems (coaxial/optical)-line on ES9038Q2M-boards..

Kommentar hinterlassen

so folks 😉 ,

as slighty feared, i´ve got a new hdmi-switch with an audio-extractor-function (also for DSD) (19€/Aliexpress)->

but got “massive” lock-problems, means its “stuttering” over the coaxial and optical line on our ES9038Q2M-boards (the “lock”-LED is constantly “working/blinking”); no constantly bitstream..(had it also often, when the soldering on pi-boards/es9038q2m i2s-line was not so optimal)..

checked the coax-cable, used toslink too: same problem..

thought first the switch couldnt deliver a constantly bitstream but connected it then to our mini-dac (Ünnlink 192Khz Digital to Analog Audio Converter  (http://essabre-90xx-rpi.sfb2.com/?p=2384)) and voilá, no stuttering/problems anymore..

okay, but i had not such lock-problems with my Sony CD-changer, nor Blurayplayer, nor Telekom-Mediareceiver over coax/toslink..

so it seems its only on some audio-devices (spdif transmitter/receiver-chips problems/incompatible) and as we had it here in discussion a thousand times (->”.. and as we know „our“ early chinese ES9038Q2M-boards had not such a good „coax/toslink/spdif-line“ (the first onboard spdif-receiver-chips were not soo good (hashtag #SRC4192/AK4113/4118) ->http://essabre-90xx-rpi.sfb2.com/?p=2211 ->“..First, on the new, blue SMPCB they use some „DS9281“ for „better coaxial conversion, less jitter, less „lock“-„problems, „better coaxial line..“),

i/we have to make/find a workaround and for this i´ve found this little nice gem->

“AK4113 Digital Receiver Board + LCD1602 Screen SPDIF Optical/Coaxial/I2S To I2S“, 25$ Ebay/->LINK

has a lot of other advantages too !! first, we got finally our “digital format/sampling frequency/digits”-display !! got besides the 2 spdif-lines also an I2S-in (will be passed through) to whom we can connect for example another hdmi-extractor (link/description at the bottom) and can easily switch between the input-channels via some simple button switch and have in any case some beautiful digital-format/sample-rate display !! 

by that it uses the AK4113 which should result in less jitter etc. too..

so, great (i´m waiting for it now) and yet to the last point today, these “Digital Interface Board HDMI / MHL to I2S / Coaxial / Optical”-device;->

had it mentioned in some articles before and because its above the 26€ duty-edge, i thought to buy it from https://audiophonics.fr/en -> https://www.audiophonics.fr/en/diy-interfaces/digital-interface-board-hdmi-mhl-to-i2s-coaxial-optical-p-15388.html ;

it cost “double the price” (same device) 50€, but its in the EU; faster shipping times + no duty problems..(and there are a lot (all) other nice things u need to have (i2s-cable,XH 2.54mm Male Socket 5 Channels connector,  toroidal-transformer, cases, all u wish)

greets for now + more to come !! 😉

I’m really satisfied with the results indeed, superior to anything I’ve got till now.
In addition I have some SACDs that cannot be played by my Yamaha cds-s2000 anymore. I can play them again with a blu ray player with even better results.
During all my tests I’ve found the result with the i2s hdmi always better than any other input (also for red book CDs)”

HDMI (4K)-audio-extractor / HDMI to I2S

Kommentar hinterlassen

so, 😉

as i yesterday connected my (Sony) blurayplayer via coax to the Sanskrit i saw only “44 or 48” at the display, means the player downsample all content to this rate (to coax/spdif) because of copyright issues/or technical limits in other cases.. (uargh..) ; you get only 192/176khz or 96/88khz via HDMI..

(btw. nice description of this “case” is here->”The extractor overcomes the restriction the visual media puts on its audio – namely restricting it to HDMI – by liberating it from its HDMI cell and forwarding it in a freed state…”->https://community.naimaudio.com/t/hi-res-audio-from-visual-media-sources/10673)

okay, and so we need a “HDMI (4K)-audio-extractor” (see other post before->http://essabre-90xx-rpi.sfb2.com/?p=2477) (i originally wanted this extractor for the “I2S-line”, see at the bottom)

there are a ot of them around, beginning at 20$ (up to 60$ or more)(this for example)->https://www.lindy.de/HDMI-4K-Audio-Extractor.htm?websale8=ld0101&pi=38167

very important seems also the “ARC”-function + EDID-support/settings (will post maybe then more about it)..

obviously its better to buy directly a HDMI-extractor with I2S output to “bypass” the spdif-conversion (and as we know “our” early chinese ES9038Q2M-boards had not such a good “coax/toslink/spdif-line” (the first onboard spdif-receiver-chips were not soo good (hashtag #SRC4192/AK4113/4118) ->http://essabre-90xx-rpi.sfb2.com/?p=2211 ->”..First, on the new, blue SMPCB they use some „DS9281“ for „better coaxial conversion, less jitter, less „lock“-“problems, „better coaxial line..”)->

i guess i´ll start with a “cheap” one from aliexpress (Link is coming..) ..

Task: with a cheap bluray/SACD-player over hdmi to I2S->ES9038Q2M

Kommentar hinterlassen

so, in short: 😉

idea is to buy a cheap bluray-player (Sony BDPS570 for example) with SACD-capability and then sending the DSD-information over hdmi to a hdmi -> I2S converter and then via I2S to an ES9038Q2M for example..(btw. absolutely “common practice” in the “hi-fi”-world).

we had such a hdmi-i2s-converter-discussion some time ago->http://essabre-90xx-rpi.sfb2.com/?s=hdmi..->

(and beware: there are lot of different hdmi->I2S sender/receiver-boards: ones are only for transmitting the I2S-signal between them and the other “extract” the audio-signals/I2S from the HDMI-stream ! (had made a new category”->”HDMI to I2S”; will explain it in a later post)

there are also complete “solutions” for that, and also i´ve read just now that u can burn your own SACDs with Nero for example..

unfortunately nothing new here in “modding” the ES9038Q2M; still on the search for the right transformer->there are some on Ebay+Aliexpress+Audiophonics but didnt make a choice till now:(15V-0V-15V)

Moode is now at V5.0-> (http://moodeaudio.org/)

and as also said in their description->
“Most USB audio devices work with moOde via the Linux kernel USB audio driver but some devices with high speed UAC2 chipsets may require the USB (UAC2) work around in System Config”
“the way-to-go” (and to get “real” DoP/DSD) is nowadays (IMO) via some XMOS-USB-device->I2S->ES90XX..
we had it here in discussion, and with the new USB2.0(3.0) linux-kernel-driver u can achieve real DoP/DSD with the ES9038Q2M; and only then..
by that, as also said, with USB3.0, + a wonderful xmos-bridge (see some posts before) + ES9038Q2M u already have a superb “tune”, really near to the “unbeaten” raspberry pi-I2S-ES9038Q2M-connection..(and its absolutely more comfortable)..
by that in speaking of a wonderful XMOS-usb-bridge we have now here a “SMSL X-USB II Digital Interface USB XMOS U208 to I2S LVDS HDMI ” (70€) with I2S->over HDMI which also said in some posts before, is the most “handiest “-possibilty to connect to an ES9038Q2M (with some I2S->LVDS converter directly connected to the dac-board)->

in visiting this great,great, diyaudio.com-forum (as said a million times before and link also in the “sidebar”)->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-338.html we have now here first a new “Dual ES9038Q2M-DAC/board“; it has also “a lot of shit” as a bluetooth-receiver and such on board, but has also an HDMI-I2S-input, see post before..(the board itself is also from “SMP CB” (like “our” green-ones))


160-200$ roundabout->Aliexpress-Link..

by that, and thats most important, someone over at the diyaudio.com-forum “DID IT” 😉 , means software-control on some internal register, HW-Vol, DPLL-settings and so on / unbelievable !!..

i dont want to write here too much about it (NDA and such), just head over to the forum->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-338.html and u will be absolutely fascinated !!

also i found just now by chance a github-repository for a driver/.dtbo for the AK-4137 on a ES9028Q2M (hifibunny-driver) or ES9038Q2M->also just discussed in the forum..->Github/TuziUsagi->https://github.com/TuziUsagi/ak4137

more to come, merry christmas and many greets for now !! 😉
