DSD Direct (again)

Yes, this version has an outdated kernel, there is hardly any support for dsd direct.
We are working on it, but this can take a few months before we have a new x86 version.

Hi,
my USB DAC randomly disconnect, his display says “NO LOCK”, and the mpd restart. I think that it restart because the effect is that the musical library is cancelled and is restarted the entire scan.

Attached my log: http://logs.volumio.org/volumio/o02OoVB.html
This is the output of lsusb:

Is there anything I can do? Or anyone can help me find a solution?

Hi Michelangelo, I’m writing you to ask to include the support for the STAR DSC PURE DAC + Pi4 Music Server. This is a no-DAC chip D/A converter that integrates a Raspberry Pi4 as a Music Server, connected through direct i2S link.
Unfortunately, even if this is a DSD native only no-DAC chip D/A converter (upsampling every file comes inside it to DSD512, converting to analog through transformers) there is no way to set Volumio to stream direct DSD files. If you play a DSD file, no matter if it’s 64/128/256/512, Volumio converts it to PCM (from 192 to 352 kHz) in both i2S or USB (through an embedded Amanero 384 input card) outputs.
Considering that this converter is able to manage direct native DSD with support up to DSD512, there is no logic behind this conversion made by Volumio.
According to the converter manufacturer, if I select “HiFiBerry” from the i2S DAC list and Direct DSD option, everything should work. But it’s not like that…
Could you please help me?
Let me know if you need further details about this DAC.
Thanks in advance.

Dsd files sound pretty good in the opption DSD with dop(pcm) and the DAC show the correct values of DSD freq. in the display.
But sound choppy and display dac show PCM 384 khz when select direct DSD in Volumio.
Thanks for Advance in your work
Best Regards

Hello,
Same for me, topping e30, if I do not select dsd over dop, I have no sound…
Are you planning to add direct dsd suport?
Also what setting sgould I do in order to see kHz instead of pcm?

Later edit:

  1. I have set dsd direct and set mixer to none. Now I have Sound.
  2. If I select dsd direct and hw mixer, I have no sound.
  3. Since I do not listen dsd files why the option to select dsd has an influence on other files? I thought this option applies only to dsd files
  4. If I do not listen dsd files what will be the best option to set : dsd direct and mixer set to none or dsd over dop and mixer set to hw?

Thanks

Hi,
Strange,
Dsd direct and mixer is set to hw, dsd files plays ok on topping e30. On display I see dsd.
