Hi,

   On New kernal 4.14.2x or above S24_LE (24 bit) not supported by KALI , to work need to enable resample 32 bit on volumio.

   Go to playback option you will get Audio Resembling option in bottom.

With Regards

Thank you for the quick response! It works, but Kali and Piano are still able to do that without software resampling?
Your colleague Michelangelo gives the advice in the Volumio: So I don't suggest to enable resampling with Piano:

It feels like a kind of trick to get playing hi-res samples with kali/piano

hi there,
I would upgrade my set from RPI2/Kali/Mamboberry to RPI2/Kali/Piano2.1.
Unfortunately only my "normal" 44.1/16 music files play in this configuration (dual mono and dual stereo).
All other formats (like 88,2/24 and 96/24) sounds like a hard continuous hiss. no music, only hiss.
I cleaned the 40 pin connectors, reconnected the parts en reflashed the software.
Latest version of Volumio. power via IFI 5 v power suply.
Piano2.1 without Kali plays great all formats and back to Mamboberry/Kali also no problems with formats >44.1/16
Reinstalled everything, tried all settings in Volumio, but nothing helps?
Please can you give me the golden key?
I look forward to the moment that I can use my Kali/Piano combo!!
regards, Jos

One month has passed. No decision, no reply. It''s not support.

Hi, As per your output "bus4 not listing",Means USBridge not plugged properly to sparky.
If it plugged properly you will get output like below
...

Hi, is that possible? The USB worked fine but suddenly stopped working. And I have never separated USBridge from Sparky, just opened the case to get to the memory for image writing, and change the jumper for separate power. After the USB stopped working I changed back to use shared power from the USBridge (jumper on) and since that works, the bridge and Sparky must be connected in some way.

Now I changed the file and rebooted. Got:

 lsusb

Now I burned the img-file to the bootcard, and rebooted. No difference.
