That is why I ended up with a BBB with the Botic kernel (after 2 RPI3, and OrangePI and a NanoPi) and that handles at least 2 channel DSD512.
Thank you. Same here, albeit I'll have to rework the software seriously (if not move away from mpd+upmpdcli) in order to make dlna commands not THAT laggy on BB. Even a dualcore Pi with vanilla Volumio is way more responsive...

greetings all,

finally had time to test the pi isolator. At first I would like to feed a home made ess9023 dac. Has anyone had success with latest piCorePlayer and if so, what driver should I set the PCP I'm running on a pi zero W.

regards.

Hi,
is there a PCB layout (Eagle or Gerber) for the RaspberryPi I2S adapter or can this also be ordered online from github?

Kind regards

Does the isolatorpi do anything for bass? Punchier bass? My setup is lacking low end. Not sure if I should invest in the isolatorpi first or an external dac.

Correct me if Iím wrong here but isolation is all about removing external negative influences and maybe cleaning up the digital signal.
As such, the best possible result is a clean and correct signal at the output.
If your signal has somehow gotten corrupted in such a way as to cause issues with your bass, it might improve your bass. But ultimately itís all about cleaning up the interface and can help with any problem relating to that particular issue.

SUCCESS YAYYYYY after a longe fight(with volumio and moodeplayer) i tried the latetest picoreplayer 3.5 audio optimized version and now my soekris Dam1021 can play DSD128 HURRAYYY i everytime dance when i see the small led on ians board light up when it shows true DSD stream also the serial port of the spoekris says L05M which is DSD128 5.6mhz yay and i have to say the picoreplayer is overall very nice! the logitech media server works fine AND before my Soekris didnt like 16bit 44.1 files now they play like a boss D: i also have the ardam board from dimdim running and this also works fine
Settings i need to make in the picoreplayer to make it work:
for my Soekris DAM 1021 i used:
-on the main page scroll to the bottom and then check the beta tab
Squeezelite settings:
-Generic/simple ESS9023 DAC
-under the DAC is "card control" tick that and tick 384k
-on the bottom "Set Squeezelite Binary: Native/DoP DSD Squeezelite Squeezelite with DSD (DoP or native) patches."
-and finaly add Device supports DSD/DoP: 0:dop

this worked for me

hope that helps
cheers janosch

That is great but did you post this in the wrong thread - or perhaps it could be in both this and in "soekris dac" thread

Hi Janosch,

That's great, you did good job. Congratulations!

A lot of people are straggling with RPi 384KHz and DSD128 , and now, here we have the answer and solution.

I'll try this latetest picoreplayer 3.5 audio optimized version and I'll let you know if I have question.

Regards,
Ian
