I used the Piano from when it first became available as a used part (to reduce costs). It worked fine up to Volumio v2.389 (or some version later) also with Kali (even 24Bit) - and all options have been available (e.g. Dual Mono). Very impressive sound.
Some day - i don’t remember the exact version number of Volumio the Kali began to produce noise with 24 Bit. It has been reported that the kernel has changed and therefore it is not longer possible to use the Kali without resampling to 32Bit (never found an explanation for that kernel change).
Later things gone even worse since Volumio lost the DSP options in the GUI to do the settings for the Piano 2.1 (Dual Mono in my case).
That is not fixed properly until now.
I do have the impression that the communication between Allo and the Volumio team has broken or none of them is able to fix the problem - leaving the customers alone…
I tested with v3 beta and found very odd issues i already reported on the Beta RPI thread.
No one answered to that.
I really hope that this could be fixed in v3 - i guess both Allo + Volumio team will be required to take care of that.
And if only someone could explain that kernel change that made it impossible to use the Kali without resampling to 32 Bit.
Unfortunately i bought quite a couple of “Kali-Piano2.1” combinations. Now i am lost with ancious versions of Volumio to be able to use them. A sad thing.
I think Allo should not leave their customers lost with that - and it would be nice if some Volumio developer could take care on that…
That’s the sad story with Kali and Piano 2.1.
I wonder how Tim Curtis went around the issue ???
Isn’t it possible to work together with him ? ( I know he uses a completely other approach…)
I would love to be able some day (e.g. when Volumio 3 is ready) to use the Kali-Piano2.1 devices again together along with Volumio.
