I2S over HDMI->short compendium TX/RX_C1 (PS-audio-standard) vs _C2 (newer) / pinout

so, 😉

as i bought some HDMI->I2S receiver-board, connected it via some hdmi-cable to my audiophonics-hdmi-extraction-board and got no sound at all 😉 , i just had to get more “in depth” with the different hdmi-pinouts (namely C1 (PS-audio-standard) and C2..)

on my hdmi-extraction-board i have these description->

TX_C1“, means the “old” PS-audio-standard” with (in short) “Data-” on Pin 1 (vs. “Data+” on pin1 in TX_C2)->

so, and as i got a “TX_C1” (hdmi-sender/transmitter) i just need a “RX_C1” (hdmi-receiver)->easy as this 😉 

needless to say that i bought a “RX_C2” for my “TX_C1” 😉

(LINK Aliexpress (14$))

hope that helps a little bit (and i hope i got it right !!) and so we can get a little further in this great “DSD over I2S/HDMI-journey” 😉 ..

many greets for now !! 😉

SACD_extract 0.3.9.3-099/-GUI / difference between Philips and Sony .dsf/.dsdiff-files

so, 😉

as i wanted to play finally my .dsf/.dff-files on the Sony BDP-S7200 (via USB, not to mention over DLNA) i´ve got always a file is corrupt or wrong media-format“ (->http://essabre-90xx-rpi.sfb2.com/?p=2618)..

found then by chance an article in which is written that the files has to be “flagged” (more or less) as a Sony or Philips .dsf-file..

on www.sacdr.net they say:”Sony SACD-Format is DSF, Philips SACD-Format is DFF” , don´t know if this is true/right but this leads me to the “sacd-extract.exe” + GUI in which u can checkbox “Output as Philips dsdiff-file” or “Output as Sony .dsf-file”..->

did it, and voilá:->it works !!” 😉

u can get the “sacd_extract.exe” (-0.3.9.3-99) from here->https://www.videohelp.com/software/sacd-extract

(direct-link Win64->https://www.videohelp.com/download/sacd_extract-0.3.9.3-99-win64.zip or here->http://essabre-90xx-rpi.sfb2.com/driver/sacd_extract-0.3.9.3-99-win64.zip)

the according GUI is here->https://sourceforge.net/projects/sacd-extract-gui/

(now in V1.5.0.1; they changed the gui a little bit)->

(also here->http://essabre-90xx-rpi.sfb2.com/driver/sacd_extract-gui-winforms-dotnet-1.5.0.1.zip)

okay, listen now to the .dsf-files but heavy white noised because of now little connection problems over I2S between the hdmi-extractor + ES9038Q2M, but will solder new I2S-sockets on it, we´ll see..

so many greets for now + much more to come !! 😉

Raspbi HAT ES9038Q2M / Ustars R38

so, 😉

found by chance this ES9038Q2M-HAT (38€, Aliexpress->LINK)..

interesting is that they use an “OPA1612” (i´ve just ordered one too, because i´ve often seen ES9038Q2M with this op-amp and will test them against the other op-amps i have here (Burson V5i-D, AD797, OPA627AU , Muses8920 etc,etc..))

by that they say in the description:”..Professional IIS verarbeitung chip realisiert PCM/DSD ausgang. 2. unterstützung 32BIT/44,1-384KHZ DSD64-DSD128 ausgang”, means they found apparently another way (“..professional I2S processing..” to output DSD over I2S (which i, we hadn´t got solved here (we used then a usb-bridge (or “new” now via HDMI))

u can also use an oled-display (+10$) directly connected (see pictures)..

else nothing new from here, greets for now !! 😉

Raspberry Pi 4 ->DSD(.dsf/.dff)-files over HDMI / HDMI to I2S-extractor arrived..

so folks 😉 ,

hooray, today the hdmi to i2s extractor (from audiophonics) arrived ! 😉 (more later)..

but first, these “Raspberry Pi 4 DSD over HDMI”-thing:

i´ve read the days that openelec, Volumio, Moode + picoreplayer are also capable to sent dsf/dff(DSD)-files via hdmi-out on the Pi-4..

thats also a very nice “alternative” because u didnt have to use an usb-bridge (which is absolutely + in every way necessary) to play DSD-files from a Pi-(X) to an “chinese” ES90XX-board..(we didnt get it to work only over I2S)..

the Pi-4 should now be capable of streaming (also multichannel-DSD) via HDMI (was not (or less) possible with the Pi´s before)..

i´m reading just now a lot of it and will post then more about it..

so, and yet to the (long awaited) “HDMI-I2S-extractor” 😉 ..

“rock-solid” (not soo heavy as the before mentioned Burr-Brown-implementation in the Philips Fidelio BDP9700), but very “steady”..

in first using and setting it up, it has 2 red LEDs flashing/blinking) and no picture/sound and i´ve read elsewhere before that u have to use a 5V external power-source (although its not necessary as per “description”)..

okay, feeded it with 5V,2A and had problems (again) with the I2S-line from the extractor to the “green” (SMPCB) ES9038Q2M, not soo with the JY “Blue” ES9038Q2M..

ended it up now with a coax-line from the extractor directly to the coax on the ES9038Q2M..(but only for now, for DSD(native) u need the I2S-line)

and got finally my lovely 192/24 😉

as said, very “solid”-sounding, almost like the Burr-Brown-Gear in the BDP-9700; very exact, another step in the “hi-fi”-direction..

so, the problem is now that my Sony BDP-S7200 should play .dsf/.dff-files (SACD in anyway) via usb/network, but don´t do 😉 

got/always say “file is corrupt or wrong media-format”, + i havent got a single !! SACD here, so i couldnt test the DSD-functionality (and that is/was originally the reason for all these devices lately !!) right now..(but i´m on it !!)..

and so, these Raspberry Pi-4 playing DSD-files via hdmi came to my mind..

(i do play here with volumio->usb-bridge->es9038q2m .dsf/.dff-files “in native” but for test here the hdmi-i2s-extractor)..

(will post a lot more about it)..

so, many greets for now, hope u enjoy the pictures, much more to come 

and stay tuned !! 😉

Little update: ordered the hdmi to i2s extractor from Audiophonics..

so folks 😉 ,

a little update concerning the hdmi to i2s extractor->

bought/ordered it right now from audiophonics->https://www.audiophonics.fr/en/diy-interfaces/digital-interface-board-hdmi-mhl-to-i2s-coaxial-optical-p-15388.html

->we´ll have to see how it works out here..

but according to another user @aliexpress (he bought it with a black plastic case) it seems to work (toi,toi,toi (german phrase) 😉 ) also with a sony blurayplayer (guess he played a SACD)->

(don´t know the excact Topping-model/series he had there)

so, much more to come, many greets from here !! 😉

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

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..

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..

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 !! 😉
