It is possible to implement these drivers in Sankeoil?

The tools are already available - i'm guessing perhaps you used the wrong mode? Most likely you need to select

Setup the DSD mode. Try DSD 32 big BE first, and make sure you're using the correct USB ID and ALTSET.



Once you have make your changes. To do a quick test, unplug and re-connect your USB DAC. Use MPD v21 and set streaming to native mode. If you set this up, the player section will always display the native DSD bitstream when you're playing a DFF/DSF file. This means it is bitstreaming in DSD format out that USB port identified by the USB ID.

Now if that is the bitstream your DAC can decode, then you'll hear beautiful almost analog music coming out your DAC .

But if you are using a Amanero board, depending on the firmware the USB receiver is using, you'll get mixed results. Microsoft and Linux uses the USB data transfer in different works (e.g. ASIO is different from Linux USB audio), and it appears Amanero is designed for Windows/Mac users in mind, and less for Linux.

XMOS works better in Linux, for Linux players it's probably ideal to look for this receiver. Or just use DoP - that's what my DAC uses as the receiver is incapble of native DSD input. Honestly don't feel like I'm missing out on anything, yet.

Edit: Forgot to mention, you only need to configure this DAC once. The settings will "stick" on reboot. Just remember to update this setting if /when you switch DACs. I can make this support > 1 DAC if there is a demand for this feature.

Could you configure these Asio drivers for Ubuntu?
Would you recognize my DAC like this?

They are different things unfortunately..

In Linux, libasio is a network library - modem, networking, etc (basically anything to do with Asychronous Input/Output ).

In Windows, ASIO means Audio Stream Input/Output.

Do you know what USB receiver your DAC is using? THe specifications page you provided didn't shed any light on that unfortunately.

I send you an option with the same chip in a raspberry.

Those chips are not the USB receiver. And the Pi version uses I2S... Can you go to the Snakeoil menu, and under Native DSD setup, click on the magnifying glass in "USB ID", and let me know what ID your DAC is?

I'm almost certain that's the Bravo chipset (coz it's the same chip I'm using inside my Accuphase DC-37). I'm afraid in Liunx this receiver only works with DoP. Sorry.

Edit: You can try DSD_U32_BE and see how it goes, that's the format this chip is supposed to support. Make sure you either reboot the PC (or disconnect and reconnect the DAC) after you have made this change. WHen you are in MPD v21, play a DSD file. the output stream will be sent as DSD bitstream, but whether your DAC will decode that properly or not is the question (I'm not hopeful to be honest).

Almost ... the DAC has changed the color led now is 88.2kHz / 96kHz. This is with DSD_U32_BE and Altset 3.

Also try ALTSET_1.

If still getting high frequency noises,then it's not going to work. For Linux playback your best bet is to get a USB receiver that uses the XMOS chip.

I have already tried in altset1 and it doesn't work
It makes no noise, it sounds great, I would say even better than the Foobar that I have, which works in native DSD.
The sound is much more elegant and precise, with a sweetness that seems to have a valve amplifier.

I will use it then as a PCM, is this the best option?
Or as DoP?
