Just picking up on this. On your S3 if you're using other apps (Spotify, Netflix, Google Play etc. etc.) can you adjust the volume fed to the Dragonfly using your phone's volume buttons or are you restricted to using USBAPP to adjust the levels (software volume control)?

 

I'm starting to think  if it's the latter the DF might not be a good match for the Moto G as I primarily use Spotify for listening. Space is also at a premium as I only have about 3gb useable space left after the OS and other apps.

 

Cheers!


The Dragonfly 1.2 only works for me through USBAPP.....so its restricted to the app's volume control.

Thanks - I appreciate the confirmation.

 

Suspected that was probably the case, but hoped it wasn't. Looks like I'll have to dip my toes into Fiio waters (E18 a probable candidate) as there doesn't seem much else around that price point that offering full volume control.

You should be able to go to Settings and under Volume Control, choose Hardware Volume Control.

Has anyone tested  AirStash.that seems to be a "magic" solution to our storage issues ?

Just that you know, you can also use most USB drive via the USB OTG cable you have for the DAC/amps and no need for something like that. Only MX player seems to support it.

 

At £80 + big SD, it ain't cheap or slick as larger internal storage.

 

Magic solution, I say would be 128+GB microSD cards... Unless you have a LG G2 and such without a slot.

Seems to be acting stubbornly for my tablet at the moment. Try toggling back and forth till it starts working.

Just go to the page linked with your PC, download the last version on one of the last pages. You need to run it on your PC while you're connected USB and follow screen instructions. Did you try? Where are you stucked?

I used the setup. and ran the prompt but it stopped at "waiting for device"  or "waiting for adb". I don't remeber exactly what it said but it didn't run. I have adb debbing set on on the phone, and it isn't set as a media device, so don't know what the problem was.

Hey Jellofund,

I too own a Moto G, and have been actively looking for a nice sounding Spotify extreme solution. After much reflection I finally ordered the Stoner Acoustics UD110 V2 DAC, and plan to use it with the only amp I got (Fiio E5) until I can upgrade to a better amp in the future.

The UD is said to be a great DAC for the money, and the V2 versions firmware is updated specifically to support Android USB Audio Control - and has proven to be plug and play happy (as in no reboot of hardware needed) with the Samsung Galaxy handsets running 4.x OS. It will also output any apps audio irrespective. I hope to have it delivered by the end of next week and will report back as to how well it functions with the Moto G. Fingers crossed I got me a winner as I find the G's onboard DAC to be mushy, bloated and dull sounding.

Thanks swab.

 

Would be interested to hear how you get on. I'd really prefer a dac/amp in the one case ideally but I guess the Stoner is so small it might be viable.

 

I currently have an Epiphany Acoustics E-DAC (ODAC) and whilst small it's just too big to carry around with a phone and amp. Works really well though and coupled with an O2 amp I find it gives a considerable improvement in SQ compared to pluggin my 'phones directly into the Moto G.

 

Another option I'm considering is the JDS Labs C5D. On paper I think it should (famous last words) work but at around £200 / $300 USD it's a bit of a gamble.....

Did you download the 1.2 version or something like that which is in one of the last pages of the thread? the version in the first page DOES NOT work, it gets stucked on "waiting for device".

I don't think hardware volume control is available on the SG S3 when using with USBAPP

Developers of some USB DAC and of some Android devices don't have the same understanding of the USB specification: an example

http://forum.xda-developers.com/showpost.php?p=48368893&postcount=333

 

"I was puzzled because another contributor to this thread (SetiroN) had basically the same setup that I did -- a Nexus 4, an AOSP-based Jellybean firmware (in his case, CM10.1), a ziddey OTG kernel, and this patch -- and it worked perfectly for him. I went so far as to wipe my phone, start from scratch with a CM10.1 install myself, apply the exact same ziddey kernel that he reported was working for him, plus this patch, and STILL I would have the same issue.

 

The only thing different was the DAC he was using. So I sourced for myself one of the same DACs (ELE DAC EL-D01, from Chinese-based eBay seller, ~$15USD), and whaddya know: worked perfectly.

 

It turns out that not all USB Class 1 Audio devices are created equally. And, as far as I have been able to figure out, the problem isn't that one device or another doesn't follow the spec, but rather that the spec allows for some variability. In my case, I eventually discovered that the DACport was reporting to the host that it supported sampling rates of 44.1/48/88.2/96kHz, but ONLY at a depth of 24-bits. In contrast, the EL-D01 reported that it would only accept 44.1/48kHz at 16-bits natively. (You can interrogate the DAC by looking at /proc/asound/card1/stream0) The DACport actually does support playback of 16-bit samples, but it expects the host to pad each sample that is narrower than 24-bits with zeroes. Apparently this is not all that unusual, and other OSes with native USB Class 1 Audio support know to do this (Windows, OS X, etc.).

 

I eventually discovered that CEntrance had actually written an alternative version of the DACport firmware a couple of years back that eliminates 24-bit playback support and causes the DAC to report only 44.1kHz and 48kHz rates at 16-bits; they apparently did this after it was discovered that the iPad Camera Connection Kit exposed a full-blown USB host controller in the iPad and that iOS apparently has USB audio support built-in, and some of their customers wanted to use DACport with an iPad. Apparently iOS at the time didn't support 24-bit DACs, similar to Android today. CEntrance would provide customers with a copy of this alternate firmware upon request, and after flashing it to your DAC, it would indeed work with an iPad (at the expense of support for 88.2/96kHz sampling and 24-bit-wide samples in the DAC). CEntrance eventually stopped publicly distributing this firmware build because iOS eventually started supporting 24-bit DACs, and so the standard firmware could be used with iPads out-of-the-box without difficulty.

 

I managed to get a copy of this old "iPad" firmware for the DACport, flashed it to my DACport LX, and voila, as they say: it, too, now works perfectly fine (with hot plug/unplug) with Android 4.2.2 on my Nexus 4 using the jacknorris patch."

The stock CEntrance DACport can work with the stock Samsung Galaxy S3 using USB Audio Recorder PRO:

Developers of the CEntrance DACport and of the USB Audio Recorder PRO (/ USB Audio Player PRO) app have the same understanding of the USB specification.

 

The stock Samsung Galaxy Note3 with native USB Audio can also work with the stock CEntrance DACport.

Samsung's developers of USB Audio have made progress.
