Debugging USB DAC (if crashing or not recognized)

Post by dmitrykos » Thu Oct 22, 2015 8:30 am

Since 1.68.0 version on Android platform Neutron provides ability to output to USB DAC directly if corresponding option is switched on.

That option is named [Direct USB Driver] and is located in [Audio Hardware] section of Neutron's settings. By default [Direct USB Driver] is switched off and the audio routing is done via OS with standard Android's format limitation.

If you switch on [Direct USB Driver], attach USB DAC (or it was attached) and Neutron crashes or nothing happens in Audio Hardware dialog (device name not changed, Frequency section shows just one frequency) then most probably your USB DAC has non-standard USB descriptor which has bug (majority of Fiio devices has buggy USB descriptor). Neutron is trying to be fault tolerant but it is impossible to foresee all possible situations, thus your help is really appreciated.

To help in debugging please provide the USB descriptors dump which can be obtained by several Windows tools. It would be great if 3 dumps are provided:

1) By USB View Microsoft's utility which comes with Windows SDK (here is latest version from Windows 10 SDK: http://neutronmp.com/download/tools/usbview.exe). Point to your DAC in the list -> navigate to File -> Save Current View... -> you will get TXT file with dump.

2) By Thesycon's USB utility (http://www.thesycon.de/eng/usb_descriptordumper.shtml, download: http://www.thesycon.de/tdd/tdd.exe). Choose your DAC from the list -> File -> Save to file ... -> you will get TXT file with dump. It can be useful to have HEX version as well, for that: Options -> Show Hex Dump -> -> Save to file ... -> you will get TXT file with dump.

Please post here your txt descriptors along with device (USB DAC) model. You can use quotes CODE

Code: Select all

  to post them in a separate area for easier reading.
Or if you do not want to post on forum, please e-mail to neutronmp@gmail.com.

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

Post by DarBur » Sun Oct 25, 2015 10:59 am

Hello. I like Neutron player a lot, its quality, functionality and the looks (especially spectrum analyzer, that one is awesome ;] ) But I have a problem using Neutron with my USB DAC. I'm using Fiio's X3 2nd gen audio player, it works fine (in DAC mode) on a PC, it work fine on Android with USB Audio Player PRO, but when I'm using Neutron my X3 is playing only at 44.1kHz 24bit no matter what I set in Audio Hardware settings (Direct USB Driver setting doesn't seem to change anything), no other options in Frequency setting. So I can't play 192kHz audio properly.

My specs:
Phone: LG G3 Android 5.0 stock, no root.
USB DAC: Fiio X3 2nd gen, lates FW 1.3.
Neutron: v1.86.2, ARM7, NEON.

My dump info:

FiiO USB Audio Class 2.0 DAC (VID=0x2972 PID=0x0003)

Brought to you by TDD v1.83.0, Mar  7 2014, 14:22:05
Hope this info will help to find the problem and solve it, would be very grateful and happy ;]
If I missed some important info point it out please.

EDIT: Tried v1.86.3 - the problem still persists.

EDIT: Tried v1.86.4 - the problem still persists.

EDIT: Tried v1.88.1 - LG G3 (6.0) + Fiio X3II (FW v1.4) now works, but X3II allways recognizes audio as 32 kHz, if I set other frequency in Neutrons settings then music gets distorted. Tried different combinations in Neutron's settings, no success.

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

Post by TYA » Fri Dec 18, 2015 5:34 am

I am lucky with iBasso D14 on 1.87 works fine.
On 1.86, it wasn't working any time.
However one tip for connecting : try at time you have full ycharge your dac and switch off charging togle of the dac

Hi, hoping you can help. Vodafone Smart Prime 6 phone (should have OTG capability) is not recognising my Fiio E17K. Fiio works fine from laptop. Between phone and DAC I'm using micro usb to micro usb OTG cable from Hakshop. I tried two in case of faulty cable. DAC charging off. Just posting the tdd.exe dump, hope this is enough. May be able to get the Windows USBView later. Thanks.

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

Post by octie1968 » Tue Feb 23, 2016 2:33 pm

Hello, I am using a Fiio K1 DAC with a Blackview Alife P1 Pro. Everything OK (except of DAC volume control through phone buttons not working, selecting option in Neutron settings crashes playback). The only remarkable issue is that since latest Neutron update the default Android 'Music' app launches every time I attach my DAC, so it's running together to Neutron in a very annoying way. Never happened previously. Any help appreciate. Thanks in advance for your cooperation.
