Post by sju8y7gtsb » Tue Apr 26, 2022 5:11 am

It works with other Hi-Res Music apps but not with the Neutron player?

Please help

Re: Debugging USB DAC (if crashing or not recognized)

I'm not an expert to help you, but please advise.
I bought a Mini PC (China, which does not make noise) to play music in Windows. I installed Neutron MP - trial. I have a Sabaj A30a amplifier with USB C input, digital amplifier (directly converts digital signal to PWM, no need DAC), uses XMOS XU208… (supports windows but not android). Unfortunately, the sound through USB did not go through, and the computer reports that there is no controller - driver, I doubt it because I provided Sabaj's XMOS But, I also have Footbar 2000 on the PC and it works without problems in that hardware combination.
I suspect I've misconfigured the Neutron MP's driver. Which settings should I change or how to arrange them - I also tried with the 'manual' (this forum), but I didn't succeed.

Do you see an option "Audio Hardware > Direct USB Access" ?
Could you provide a screenshot of the info section at the top of "Audio Hardware" ?

Addendum – Neutron MP gets better. I said, I'm not a technician or computer scientist.
1. While my Mini PC, Windows 11, was connected to the amplifier (described above) via USB-C, (I downloaded NMP for Windows from the Microsoft Store), control with NMP was difficult, slow, bordering on "freezing" ", if I changed the input to the amplifier or turned it off, the control returned to normal.
2. I said, as a rule, I didn't get sound through NMP (for Windows). Sometimes the sound appeared - I guess the Mini PC, Windows 11, turned off the sound output option. I found that windows does not find the launcher, driver, or sound output: it offered the TV or its built-in sound option. The sound chip in the amplifier (described above) is adapted to windows - anything but android) so the Mini PC left a message to that effect. In another attempt or some change in the connection, I managed to get the Mini PC to find the output for the sound - Sabaj, the amplifier to which the speakers were connected. Clearly – to the USB-C input. Then I also got the sound by manually selecting the sound output.
3. With sound output found (Sabaj) the effect was not stable. After a musical number (song) or two, - or halfway through a song - there was an interruption. Removing the first screen, I saw that the NMP was still working – an introductory look at the NMP and the oscillator, but no sound. In Windows, the sound output display has disappeared. I had to search for the Sabaj exit again. The sound passed again, but for a short time. Final: I checked everything up to DSD512. Obviously, there is no stability of NMP for windows in combination with Mini PC (Windows) when connected to USB-C. I did not check the other entrances. - I have tried all the possibilities of Direct USB Access!

I managed to find and consolidate Sabaj as a sound track, and I wiped out the competition. I think it works stable now! And I bought a Neutron MP!
I am sending the attachment! I don't have an app for processing the screen image on the Mini PC, so I took a mobile phone, I bought a variant without a fan, for music. So in the winter, PC will play a real role with its temperature expansion.

The Neutron works stably, but the DSD label is not running on the amplifier screen - only 192.0. On the performance view, there are three squares on the right. the first click initiates the display, and the second and third two descriptions of the characteristics of the recording - I don't know what that means - it sounds the same. One description shows what the screen (PCM) shows, and the other shows what I expect from the recording (for example DSD 64), but that is not on the screen. Can an explanation be given? Why isn't DSD transferred via USB-C (audio USB)

Neutron normally decodes DSD input into PCM, because only then its DSP can work and most DACs only ever take PCM as input.
There's an option "Audio Hardware > DSD, DSD over PCM (DoP)" which when activated tells Neutron to omit the decoding and transfer the DSD input unchanged to the DAC. Did you try to activate this option ?
