I have TEAC NT-503 USB DAC, and I tried the native dsd mode.
Finaly I did it. (I confirmed the 2.8M, 5.6M, and 11.2M native mode.)

My Environment:
OS: Ubuntu-studio 16.04
kernel: 4.4.0-51-lowlatency (x86_64)
Player: mpd-0.19.19 + patch"mpd-dsd-019"
DAC: TEAC NT-503 (perhaps, UD-503 and UD-501 are also OK.)

Point:
Altsetting"3" is the native dsd mode on TEAC NT-503. -> modify kernel module.

XMOS U8 chip, it supports native mode up to DSD256 under windows. Should be able to support native dsd.
Checked the USB ID code it is different from XMOS code from lintweeaker's code, however it is still XMOS.
Tried the compiled MPD with native dsd support and it is not working. I suppose it is the ALSA part that's not picking it up?

Can you help add this support to the kernel or provide a way to patch it ?

I am currently running RPI 2 with debian based Volumio

updated to kernel
Linux volumio 4.1.4-v7+ #808 SMP PREEMPT

Thank you very much.

Hello,
I'm going to try out to listen to DSD on my ubuntu, but before I start patching my kernel I want to ask if these patches are compatible with the Debian/Uubuntu kernel sources?
I have Debian and Ubuntu machines for the test.
I'll use JLSounds XMOS board.
The question may be stupid, but as far as I see there are only RPMs in the repo, so I wanted to ask before I start.
Any ideas? Someone did this?

Is there any way to directly feed dsd data to hdmi?
So that AVR can decode it & play it

I’ve got Aune T1se (this is the third iteration of T1 that was released recently):

Let me know if you need something else. Thanks!

http://oppodigital.com/headphone-amplifier-ha-1/

Is Xmos based: http://www.xmos.com/blog/xmos/post/customer-focus-oppo-digital

What do I need to provide to get it supported? (DoP works OK)

Thanks!

Will really appreciate if anyone share the way to get 48 KHz out of Anamero combo 384. the default seeing is always providing 44.1 kHz with the clock prescalar of 1. Thanks in advance..

Oppo 105D seems to have the same XMos interface as HA-1, but the USB ID (22d9:0451) is different.

Could you add this USB-ID too xmos-native-dsd too?

Thank you much and Liebe Grüße

Hi! Can you crate global patch for all dsd dacs?

I have a TEAC-UD501 and am willing to do some testing. I looked for the 'archived' issue but couldn't find it.

Would it be possible to add support for the Moon Neo 230HAD?

from these message ,there is not interface which can support "S16_LE or S24_3LE",I want to know if there are some special setting at usb audio driver layer to compilcance with S16_LE/S24_3LE?
thanks !

Hi Lintweaker,

JLsounds converter boards supports DSD native up to DSD256.
Could you please include it to the list of supported converters if it's possible?
The USB ID of JLsounds is 20B1:2023

Kind regards
Lyuben

I have new DAC
(0x27f7, 0x1301): /* like Wyred DSD

if (fp->altsetting == 3)

break;
default:
break;

But allways S32_LE

Kernel realtime 4.4.3_rt9
Kernel standard 4.4.5
Alsa 1.1.0
Distribution: Archlinux

Is seems that DSD play is broken on these kernels (at least DoP, maybe also native)

In two different computers checked with MPD and HQPlayer
iFi micro iDSD led confirms receiving DSD signal, but right channel is muted.

Can we create packing PCM to DSD?

Hi, I'd like to mention that FiiO K3 is also based on XMOS U30881C10 (according to its amazon page) and supports native DSD on windows with ASIO driver.

The usb ID is 2972:0047

Thank you.

I am trying to patch quirks.c for DSD native output ONLY. Since this DAC is using the Gustard USB interface I have made this modification:

case USB_ID(0x20b1, 0x000a): /* Gustard DAC-X20U /
return SNDRV_PCM_FMTBIT_DSD_U32_BE;
break;
case USB_ID(0x20b1, 0x2009): / DIYINHK DSD DXD 384kHz USB to I2S/DSD /
case USB_ID(0x20b1, 0x2023): / JLsounds I2SoverUSB /
case USB_ID(0x20b1, 0x3023): / Aune X1S 32BIT/384 DSD DAC /
case USB_ID(0x2616, 0x0106): / PS Audio NuWave DAC */
if (fp->altsetting == 3)
return SNDRV_PCM_FMTBIT_DSD_U32_BE;
break;
default:
break;
}

Result: DoP is working, but native DSD output only noise
DAC is displaying PCM 176.4 when playing DSD 128 and PCM 384 when playing DSD 256 while this noise is happening

Some suggestions?

Hi!
My pleasure!
Can you some more expanded told about new method of dsd native support!
THANK YOU!

Maybe I am asking too much... but, since I have the last DIYINHK XMOS xu216 card capable of DSD1024, I would like to know how to enable it in linux. Thanks.

Hello! There is an idea to check the Native mode with this DAC. But unfortunately it locally, I can not do that. I can only prepare OS system in advance and send the person to be tested.
Maybe someone will tell USB_ID?
Maybe some like USB_ID(0x2616, 0x0106): /* PS Audio NuWave DAC */

ref.: http://www.amanero.com/drivers/nativeDSD.txt
It seems that with new firmware Amanero Card is supporting DSD native in linux. These are the data given by Amanero:

OEM Combo384 default VID=0x16d0 PID=0x71A

To enable/disable native DSD on Combo384 an USB Control request must be sent to endpoint 0. This procedure is supported on all firmware versions.
On firmware_1099rc1 an USB alternate settings "2" with a native DSD endpoint is supported.

The control request is of type Vendor to the Device.

bmRequestType=0x40,
bRequest=0xB1,
wLength=sizeof( struct VAD_DATA ),
Data is a variable of type struct VAD_DATA

struct VAD_DATA {

unsigned int command;
unsigned int length;
unsigned int buffer[64];

};

To enable native DSD
command=0x8000
length=0
buffer=undefined values

To disable native DSD
command=0x10000
length=0
buffer=undefined values

Possible to support? Thanks!

I really love your work! What do you think if we work together to integrate this in Volumio?

Some people are reporting some messages like this when this dac (in theory uac2 compliant) is connected to USB:

[ 246.137526] usb 3-1: Not enough bandwidth for altsetting 1
[ 246.137527] usb 3-1: 2:1: usb_set_interface failed (-22)
[ 246.141100] xhci_hcd 0000:02:00.0: ERROR: unexpected command completion code 0x11.

Do you think this is a driver problem?

The Armature Hecate interface is close to (maybe even identical to) the Singxer F-1.
It support up to native DSD 256 on its USB input. It has an I2S output which always produce a native DSD data flow. I'm using it with success up to DSD 128 with a NanoPI Neo or a RPI3 with DietPI and RoonBrdige. The Roon support team told me to look at this project, and it seems that here is a solution.
However the Armature Hecate is not in the supported list. The command lusb produce the following:
root@DietPi:~# lsusb -d 20b1:
Bus 001 Device 002: ID 20b1:3086 XMOS Ltd

I noticed that 20b1:3086 is neither 20b1:3008 nor 20b1:2009.

Not sure it is the correct place (by raising an issue here) to ask this update, correct me if I'm wrong, sorry in advance.

Is it possible to have an update of the lintweaker/xmos-native-dsd project that would support the Armature Hecate board ?

Thanks and congrats for this initiative 👍

It should have support for DSD native up to DSD512. The patch should use Altset3?

Hi,
this integrated amplifier:
https://www.mission.co.uk/778x/
advertises native DSD support up to DSD256 but I'm currently unable to take advantage of this with Linux because it's not recognized:
Its PRODUCT_ID:VENDOR_ID are:

# lsusb
...
Bus 001 Device 004: ID 2622:0011 MISSION  MISSION USB Audio 2.0

According to this review:
https://hxosplus.gr/reviews/amps/mission-778x-review-test/
it should have as XMOS USB interface chip and the ESS DAC.

Any suggestion how to add support for this device?
Vendor offers only a WIndows driver and is unresponsive to requests....

Has some figured out what is needed (and if possible at all) to support the D1100 of McIntosh? Playback right happens via PCM-convert through ffmpeg to 32bit/352.h kHz :-(
Thanks!

I have just checked kernel 4.4.3-rt9-1-rt, mpd-git, Alsa 1.1.0 and iFi micro iDSD DAC, playing a DSD 128 dsf file.

Both MPD and HQPlayer are working fine, led on iFi DAC is signalling DSD. Sound is right.

Alsa, strangely, is giving

access: RW_INTERLEAVED
format: S32_LE
subformat: STD
channels: 2
rate: 352800 (352800/1)
period_size: 32768
buffer_size: 131072

Mpd configuration is

audio_output {
type "alsa"
name "DSD"
device "hw:0,0" # optional
auto_resample "no"
auto_format "no"
mixer_type "disabled"
dsd_usb "yes"
}

But I am sure that only DSD is arriving to the DAC, since mpd cannot convert to PCM!
I have the same result using HQPlayer with the options DirectDSD, DoP, SDM

How do you explain this?

Hi,

Is this patch still necessary with Ubuntu 18.04 and ALSA 1.1.9?

Do we still need to compile Kernel to add native DSD support?

Thank you.

Hello Lintweaker,
I've followed your latest work on Linux, especially on Github and I tried to contact you on DIYaudio on 14th February 2016 but got no response till now. I came here to ask for a bit of your time and help me add WaveIO board in the list of devices that are supported in Linux OS as per this link:
https://github.com/lintweaker/xmos-native-dsd

This WaveIO board does not have same USB VID as XMOS like many other competing boards do because it does provide a fully featured driver in Windows and for that, I was forced to acquire a Microsoft Authenticode certificate along with different USB VIDs than those used by XMOS.

In case are needed:
WaveIO USB VID = 0x20A0
WaveIO USB PID for HS USB Buses = 0x4143

I'm assuming that you only need PID for USB High Speed bus still I have the other one for FS if needed!

As for testing, I'm only using Windows... -as the worse thing happened in my life- but I have a friend of mine who can run whatever tests we have to conduct to fulfill this request.

Thank you for your time and patience,
Lucian (Lorien on DIYaudio forum)

Brinkmann Audio Nyquist DAC is also XMOS based and supports up to DSD256 native.

VID: 0x20B1
PID: 0x3093

Can the Primare Prisma DAC be supported?

Hi,

I have an Aune S16. I'ts XMOS receiver appears to be the same as the Aune X1S which has support on the linux kernel:

lsusb gives the following:

lsusb -d 20b1:
Bus 001 Device 006: ID 20b1:3023 XMOS Ltd

If I have understood correctly, there should be DSD_U32_BE for this receiver too, however aplay -l output is:

Card 1, ID DAC', name S16 USB DAC'
Device 0, ID USB Audio', name USB Audio', 1 subdevices (1 available)
2 channels, sampling rate 44100..384000 Hz
Sample formats: S32_LE

BTW, I am also an owner of a DIYINHK XMOS based dac, where everything is fine:

Card 1, ID D20', name DIYINHK USB Audio 2.0'
Device 0, ID USB Audio', name USB Audio', 1 subdevices (1 available)
2 channels, sampling rate 44100..384000 Hz
Sample formats: S16_LE, S32_LE, SPECIAL, DSD_U32_BE.

I use latest odroid kernel which as far as I know has latest code backported with regards to the DSD format:

https://github.com/hardkernel/linux/blob/odroidc2-3.14.y/sound/usb/quirks.c

Regards,

Michael

I can not in any way get the lack of clicks on my DAC, even using DSD_Native mode.
my Ustars Audio XMOS AK4495 dsd DAC ( #8) work with your patch
format: DSD_U32_BE
subformat: STD
channels: 2
rate: 88200 (88200/1)
period_size: 11025
buffer_size: 44100

I read that in contrast to DoP mode, DSD Native does not have these problems.
I ask not to close this task!

I wrote to the developers MPD (and email to ALSA devs)
http://bugs.musicpd.org/view.php?id=4320#c9858
But no one even wants to take on this problem!
I am sure that this problem is also related to this issue by implementing support DSD_Native!
As one of the variants of the solution, I see
add delay to 500ms in

a) When start dsd files!
b) When rewinding dsd files!
c) When switching dsd -> dsd or pcm and stop!
Or add this variable in the configuration file!

I do not know who to contact! I have written to all of whom could have help , but nobody wants to deal with this problem. Thank you!

Did I understood correctly that each device has to be explicitly added to your patch?

I have:

I have your latest 0.19.10 patch for MPD (btw it doesn't compile because I have automake 1.15 and it expects 1.14 so I had to tweak this)

Playing the same file.

What should I do? Where to look next?
Is there a way to get alsa drivers detailed log to see why it insists on conversion?

Thanks for your work on the patch!

Hi, could you add native DSD support for FiiO K3? It is based on XMOS U30881C10. Under Linux, it only supports DoP up to DSD128. Under Windows, it supports native DSD up to DSD256. The usb ID is 2972:0047.

Thank you.
