Combo384 Amanero firmware upgrade for DSD256 Lampizator Lite 7

[seatrope]

Hi bodiebill, I’ve been experimenting with the new firmware quite a bit. Google “GitHub amanero Linux DSD” and you can get more info from that thread. 

 

The answer to your question is that a new driver for Windows is needed, per Domenico of Amanero, due to the new DSD handling method in the new firmware.

Hi guys. The high pitched whine has NOT been fixed. 

 

I think Domenico said he had completed the windows driver but i wasn’t paying attention as I am Linux only thru mrendu. 

 

Might be best to ask him at github. He was extremely responsive for a while and has now dropped off the map. Having dealt with him it’s understand why L and company are frustrated!

Could you please explain the pitched whine, and difficulties with AMANERO from your point of view ? 

I've heard Lampizator upgraded some DACs with new firmware (from AMANERO) at RMAF isn't it ?

 

Hi @volpone, the high pitched whine is a bug in the latest firmware (and so far the best one supporting DSD512 in Linux, using native DSD not DoP). After you stop playback, maybe 50% of the time there is a soft but annoying high pitched whining sound about 5 seconds after you hit stop. sometimes after about 10 seconds it goes away by itself. It is probably an issue with MUTE assertion in the DAC. Jussi has confirmed the same bug with his DAC as have some others on that github thread. more info there.

 

Upgrading the firmware is very easy, if you have ok from your distributor that popping the lid doesn't void warranty. I am not sure what version Lampi was placing on DACs in RMAF... let me ask Fred. They are equally frustrated with Amanero, as Amanero's promises have led to premature announcements that the Linux DSD issue was "fixed"... I now understand having dealt with Amanero directly. He's great when he replies, but when he goes off contact....

Hi @bodiebill, yes indeed. I just heard back from Domenico of Amanero that the final windows driver is just about done. Windows certification took longer than expected. I’ll post a link here soon when he sends it out.

+1. A few months ago, I thought native DSD512 by Amanero on Linux would be never achieved but the successful release of recent firmware by Domenico taught me how superficially I'd been seeing things.

 

 

First of all, I'd like to apologize for not being a Lampizator owner but as a user of Amanero board on Linux, I'd like to address that I've never experienced this kind of "high pitched whine" when playing upsampled DSD512 sources via HQ player (with or without Roon) running on Ubuntu 16.04.1 LTS (GNU/Linux 4.9.43-jl+ x86_64) since I updated the board firmware to the latest 2003be_71A almost two months ago. The board has been also working well with playing DSD512 sources, though quite limited in number, by MPD (native, not upsampled) on an Arch Linux kernel (4.13.7-1-ARCH, non-rt) running on a Beaglebone Black. On both examples, there has been no inter-track noise when playing DSD512.

 

BTW, my Amanero is i2s/dsd-connected to a Buffalo 3SE via Teleporter, all from TPA (Twisted Pear Audio). Sorry for cutting into this thread.

 

Regards,

Hi Luke, glad to see you here as a transplant from that thread.

 

i guess it might be how Amanero interacts with our DACs differently then, makes sense as it is a mute assertion. I know Jussi said he reproduced the high pitched whine on his unit.

 

@bodiebill do you get this high pitched whine at all with your setup using wtfplay in Linux? Perhaps your F0-1,2,3 setting is what did it.. do you know what that does? I have not been doing that.
