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

Post by The_FNG » Tue May 03, 2016 12:49 pm

Hello Dimitry - Last time we spoke was in December of 2013. Android had not yet embraced advanced USB tech, including OTG. I'm still using Neutron - loving the advanced parametric equalizer choices to reduce unwanted resonances, etc.

Currently, I'm running an LG-V10. It's DAC sounds wonderful, but I prefer using one of my headphone amps, the Leckerton UHA-6S.MKII w/DAC. Problem is, when I enable Neutron's direct access to USB, and then into the Leckerton, the output is MONO. Weird.

LG-V10, Marshmallow
Neutron (latest from Store)
Leckerton UHA-6S.MKII
Noble Kaiser 10U

Here are the dumps. I connected the Leckerton to my PC, and this is the data I got from both utilities.

I don't see an option to select Direct USB in Audio Hardware dialog...I assume it's not seeing the DAC?

Thanx!

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

Hey Hey,

yeah I realized the Fiio problem.
Moto E 2nd Gen LTE (XT1524 Surnia) --> Fiio Q1 - no chance
Moto E 2nd Gen LTE (XT1524 Surnia) --> Fiio E17K Alpen 2 - strange random drops, rather often (but will see if reverting back to Motorola stock ROM will bring better stability) --> Edit: Motorola XT1524 Stock Android 6.0: direct USB driver of Neutron working really bad, switching direct access off working better, but not too good - working good for a whole album in FLAC then dropping once (because of touching volume buttons of moto or entering options on Fiio) and dropping again steadily within seconds or minutes until restarting phone. Actually I checked back on a Sony with Android 5.1 with some purchased whatever-player and standard Sony-Android-USB-DAC-support and connection was flawless, regardless of using phone volume buttons or entering the options on the Fiio.

Thanks,

Of course it was my fault. After doing a clean install of Neutron, the USB OTG works just fine!! Still the best player on the market!

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

Hello everybody,

after a lot of using Neutron as my standard player, I realized, that my LG G3 has a really crappy headphone jack. I heard lots of noises, which sounded like interferences...
But now, I got my Aqua DAC, which works pretty well but the sampling rate stays at 44.1kHz, even if I choose 48kHz or 96 kHz.
i reinstalled the current 1.89.4, but with no solution. Maybe this is an issue, which has to be fixed? I tested songs, that are sampled with 44.1, 48 an 192kHz.

I added the USBView.txt as an attachement.
EDIT: It seems, that the attachment isn't shown, so here the content

Another addional information: USB Audio Player pro is able to work with the higher sampling rates, but has difficulties with the play/pause and volume buttons...

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

Hi, Neutron.
I buy LG's HiFi Plus with B&O Play (http://www.lg.com/uk/lg-friends/lg-AFD-1200) which is a DAC for mobile smartphone.
Unfortunately but, this DAC is not working properly with my Neutron Player.
Would check the USB Description below?
