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->http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-129.html, 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..
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 😉
see at the top line..
must be out for a few days now..
http://www.moodeaudio.org Forum:-> Link
(little installation reminder debian-stretch-lite: user pi pass raspberry..for ssh enabling ->sudo raspi-config)
many thx to „Blackbear“ over at the Diyaudio.com-forum http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-10.html
and because of min. 80% !! of the visitors here on the blog a searching for ES9038Q2M-related info, here are some results on his „research“:
In MoodeV4Beta on Dietpi he uses the „Audiophonics ES9028Q2M„-audio-settings..(for the ES9038Q2M)
„..Hello, in dietpi i had selected no driver = just left rpi-2835 (I left it without change after installation…), but in moode driver selection i choosed audiophonics 9028q2m, so it is strange that Moode takes control over dietpi driver (now I am thinking about it…) ? but it works, also tried to switch in dietpi config onto i-sabre-2km driver then restart and no sound so then i had to go into moode driver and to select audiophoincs 9028q2m, tehn reboot and it works again…strange..“
greets for now..
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:
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/)
because there are here so many searches concerning „Moode Audio“-image here´s a „install-script“ for an almost automated install->moode-automatic-install
its from the „official“ Moode-/supportforum->http://www.diyaudio.com/forums/pc-based/271811-moode-audio-player-raspberry-pi-1160.html
and there´s also a new „driver“-package for the Audiophonics ES9028Q2M linux-kernel 4.9.51..it came across via the „Volumio“-forum because the hardware-volume wasnt working for the new Volumio-releases..(but this is absolute „Audiophonics ES9028Q2M-related because they implemented this „HW-Volume-control“)..->Q2M_kernel_4-9-51
but another thing is, if i look in the archive there are such „i-sabre-codec.co and i-sabre-k2m.dtbo“ files which can be used for the Q2Ms too, and so somebody have to/could try to use them/modify to take the full advantages (and higher sampling-rates) out of these ES9028Q2M/ES9018K2M-chips..
any experiences/results->please leave a comment here..
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 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)
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))
absolute fabulous !!
Moode-Audio Ver.4 Beta 6 is now available via:
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)
(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..
