Hello, I am using Fedora and Topping d90SE DAC from USB.

PCM plays like a charm.

No matter wjhat i try DSD doesn't show, converts to PCM. I have checked the checkbox to output DSD.

Enable DSD bitstreaming, don't use DSP Studio > Output Format > Output Encoding to do it.

Hello, and thank you for replying.

These instructions are for Windows. I don't have ASIO or WASAPI. In Linux it works with ALSA.

So there is a checkbox in Options in audio device that says "Send native DSD" but seems to do nothing.

If I enable the output process everything is working, enforcing DSD from 128 to 512 and DAC recognizes the output just fine. So I understand that it doesn't send native DSD to output.

[Awesome Donkey]

The DSD bitstreaming option is the same regardless of OS. Native DSD support on Linux depends on if the Linux kernel has support for your DAC. As you've discovered already you can try enabling native DSD in MC'S Options > Audio > Audio Device > Device options and see if it works for you, but it sounds like maybe the Linux kernel doesn't support your DAC? Or maybe you're using the wrong audio output. Make sure you're using the hw: output for your DAC, using the default Pulse it won't work too well (plus everything is resampled by default).

Hmm in case no kernel driver, wouldn't that mean that setting manually to DSD wotuldn't work either (it works)?. lsusb correctly shows the device.

However what worries me is that ALSA shows as default device pipewire media server. I am not sure this is good. I have to check more on this.

The list I choose for hardware device shows me a big list and in 3-4 cases shows D90SE. I remember an IEC978:D90SE (or something). More details and tests on Monday

[alexopth1512]

OK I am on the D90SE now.
Here we go

Code: [Select]

aplay -L |grep D90
sysdefault:CARD=D90SE
    D90SE, USB Audio
front:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround21:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround40:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround41:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround50:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround51:CARD=D90SE,DEV=0
    D90SE, USB Audio
surround71:CARD=D90SE,DEV=0
    D90SE, USB Audio
iec958:CARD=D90SE,DEV=0
    D90SE, USB Audio
The above list is also the list that Media Center Shows. I choose "front" or "IEC978" since sysdefault doesn't work correctly
Now

 Format: SPECIAL DSD_U32_BE means on both cases that it is recognized as DSD capable?

Again, if I choose in DSP "enable format" and output "Native DSD n 8x format" works fine, both on SMSL and D90SE!

Kernel is 5.13.12-200.fc34.x86_64

[alexopth1512]

Update: It works in Windows, however upto DSD128. DSD512 doesn't work it makes "hickups".

[Awesome Donkey]

If you're using the DSP Studio > Output Format > Output encoding set to "Native DSD in 8x format" or one of the other settings, that's probably why as it's doing on-the-fly DSD conversions. Usually hiccups and stops in audio playback mean the machine you're doing the conversion on isn't fast or powerful enough to handle the conversion on-the-fly. DSD on-the-fly conversions are one of the most resource intensive operations Media Center can do. That's why it's generally recommended to avoid using DSP Studio > Output Format > Output encoding and instead use DSD bitstreaming.

If you want to find out the exact formats it supports, run the included alsacap program from a terminal.

/usr/lib/jriver/Media\ Center\ 28/alsacap

Post the result of that here.

That looks fine.
If your D90SE has analog outputs use the front: device.
If it's s/pdif use the iec958 device.

Make sure you have DSP studio output format DISABLED.
Turn on bitstreaming DSD under Tools->Options->Audio->Bitstreaming.

If the device supports NATIVE DSD enable that checkbox under Audio Device Settings. Otherwise, uncheck it and MC will send DoP.

[alexopth1512]

Me bad, me very bad boy 

I didn't pay close attention to enable Bitstreaming

Everything good now. Excellent! Happy I bought the product

I can play now 512 DSD, it sounds soooo nice...
