When it was 4.1.2 was using USB Recorder Pro. When I connect the unit it will say "usb device initialized" something like that..

Thank you, that's a sum of infos !

I get that my stock Android (4.1.2) phone should play the music with my DAC ! It is unfortunately not listed (UCALL). I will work on it.

I'm curious as to whether it's feasible to expect the following solution to work :

attach an unpowered USB hub, with both my flash drive and UD110 DAC plugged into it, then attach the hub to the phone via OTG Y cable, with the power connection of the OTG Y attached to mains or computer (to power/charge the phone), and manage to playback files from the flash drive in UAPP on the phone while outputting the audio to the UD110 ?

I have already tried and failed to get the USB hub (linked below) to work with a standard (unpowered) OTG cable, both with the hub plugged into its own mains adaptor, and with the hub drawing power directly from the phone itself...

I see there was much discussion way back on this thread relating to how some phones would only route audio through USB when using a hub connected to the phone (or some such). If anybody has any advice as to a USB hub (powered or unpowered) that might allow this type of functionality (give or take the OTG Y supplying current to the phone) or has any knowledge of such a setup working successfully then I'd be delighted if they could share their experiences with us, before I randomly start shelling out money on hubs right left and centre etc.

Cheers,
swab

 

As a reminder, you don't have to use a USB hub in order to connect external storage to an Android device while using a USB DAC. You can use a Ravpower FileHub as mentioned here. HTH!

But yeah, cRoid Simple is probably my next rom/kernel combo of choice.

 

I flashed cRoid Simple and had some weirdness with ring/notification tones not showing up. Rather than reflash it I flashed HellKat just for a look and it's really good. I'm not keen on the red UI and some of the English in the menu options is pretty bad, but I can live with that. My FiiO E07K works fine and the battery life is epic. LTE, WiFi, Bluetooth, GPS, and everything else is enabled, running for 7 hours and only gone down to 87%, and that's including 45 minutes of bluetooth audio on my commute.

 

Daily builds as well :)

DanBa - many thanks for the great resource list you've put together.

 

I've been searching without much luck for a right angled USB Mini to Micro OTG cable for use with my C5D, as the straight one that I got with the C5D isn't really practical for pocket use (adds 2" length and very prone to cutting out if nudged).

 

One of your links lead me to the Treeo one which looks perfect. Only £4 ish too which is much less than getting one custom made but the The only downside is the shipping costs which bring the total up to around £20!!!

 

http://store.treoo.com/main/nocturnal-audio-right-angle-mini-usb-to-right-angle-micro-usb-otg-interconnect-cable.html

 

I'm going to order one anyway but wondered if any of the UK guys in a similar predicament were interested in a small 'group buy'? Adding another 1 or 2 to the basket only increases shipping by £3 or so, so I'm thinking that a 2 or 3 way split would make the unit price a bit more wallet friendly even after a small allowance of 60p for a first class stamp to forward them on. Each cable would work out at £14 delivered if buying 2 or £11.50 delivered if buying 3.

 

If anyone's interested let me know and I'll stick in an order. Wouldn't need any cash upfront and once they were to hand I'd create a thread in trading to keep things above board :)

 

(mods - hope I'm not breaking any rules by posting this, but if I am please feel free to delete/edit as appropriate. Thanks!)

Hi folks. Seeing as the Galaxy S3 is compatible with otg dac use, is the S3 mini good too? It appeals for its size, weight, sd card slot, removable battery and price, although will wait for better deals.

You're S3 does not have a card slot or removable battery?

Not in stock form.  Neither the S3 Mini nor S4 Mini support USB OTG (or host mode).  Apparently the S3 Mini can get sort of OTG support if you root it, modify some stuff, and use a powered USB OTG Y-cable.  Just google "galaxy s3 mini usb otg" for some links to the xda-developers forum.  I wanted to downsize from my current S3 to something physically smaller and looked at both the S3 mini & S4 mini but neither will do USB OTG.  My next phone may be a Sony Xperia Z1 Compact since it does have USB OTG and microSD slot.  I can live with a non-removable battery, but I need USB OTG and microSD slot.

Hey Guys, was at Costco today and saw a Galaxy Tab 3 8.0 (wi-fi only) for $240. Anybody have any experience with this chained to OTG + Dragonfly thru UAPP? I really love love love the sound quality out of my GS4 with the same set up and would like to recreate it with the Tab 3 8.0. Just wish it had dual microSD slots.

I currently have the Galaxy Tab 2 7.0 but does not sound nearly as good as my thru my GS4. I attribute that to the OTG cable for the Tab 2, which is not as good a quality as for my GS4. Since the Tab 3 8.0 has the same micro USB as my GS4, I can use the good OTG cable with it.

Thanks for the info and shame about that. 

 

The sony looks a contender but way too expensive for the time being.  Call me a cheapskate but I'm not willing to spend more than £200 on any phone- tops.  They just ain't worth it imho..:regular_smile :

No experience with the Dragonfly but have recently bought a Tab 3.8.0 and have a cheap OTG cable on the way.  Will hook it up to a Hifimediy Sabre U2 async via USB audio player PRO once it arrives.

Just bought my first ever phone(always been supplied phones through work) in the very impressive Sony xperia Ray,little dynamo of a phone,works with USBaudio player pro,even though it says its not supported in there data sheet,plays 24bit 96k downsampled to 48k,it doesnt sound great not enough power but it works!

The Ray also plays these HD tracks straight out the headphone jack which was very suprising!

 

 

 

Just an update on this set up,i tried this again tonight and the sound was excellent playing muse the 2nd law 24bit 96k,its as if the player was getting used to the new output,although the fiio e7 downsamples to 16/48,need to get a small 24/96 dac that will piggyback onto the Ray!thinking about the audioquest dragonfly,has anyone connected one up to there phone?Any other suggestions?cheers.

 

Tried it with mdac,still needs a usb hub for the 24bit stuff,but it plays 24/96 ok with a £1.00 usb hub,£2.00 otg cable and a £5.00 app, not bad for a cheap two year old phone!!

Sorry I'm a bit late to this but I have just been playing with various connectors, adapters, hubs etc with a tablet so I thought I would have a go with my Moto G after reading this.

I presume you ( swab ) are updated to the update to 4.4.2 ! ( Originally the Moto G worked with OTG attached drives but this was lost with the original 4.4.2 update. However, that has now been more or less sorted by a further update ).

 

I had confirmed that this new update was working but had not tried with a hub. I have a micro USB OTG Y adapter which allows further power to be supplied, but the first thing to realise is that this does not power the phone - it only powers the hub and items attached to the hub. I can confirm this is the case with a couple of hubs I tried with dac and drive attached. I played some tracks through the dac from the phone OK, but the drive was NOT recognised on the hub ( although it is recognised and can be accessed when attached directly to the OTG adapter ). So, it looks as though Motorola/Google have only partially solved the problem. ( My Samsung Note 8 can access the drive and dac and a mouse/keyboard all attached to the hub at the same time although the hub does need to be powered ). So this agrees with your findings with your hub experiments and it is unlikely to work unless there are further relevant updates.

 

It would seem that your best bet is some kind of wireless access to external files such as that suggested by Theogenes, above, and plug your phone directly into the dac via OTG.
