Android phones and USB DACs - Page 278

post #4156 of 5444

If you are at home, you can at least power the DAC through a powered hub. I just confirmed that the DragonFly and the Fiio E17 both works when connected through a powered hub (a 15 year old "MacSense" USB hub, no less). The DragonFly lights up even when the phone is not connected, and the Fiio shows its charging light.

 

Now, of course this "should" work, but you never know.... but it does not seem to charge the phone, which I also think is expected - a USB host is not supposed to draw power from a client device (or hub). It is possible that you can fool the phone, but can you fool the hub to supply power?

success! found the usb power off switch, on the E17 and things have definitely improved, not perfect as there still appears to be some power drainage from the DAC as SV_huMMer suggested but a worthwhile improvement......I think I'm gonna buy a spare phone battery and OTG Y cable to cover my bases.... Can anyone point me towards an inexpensive mini-micro-standard OTG Y cable?
Once again, a really big thanks for the help given guys, It's much appreciated : )

Thanks for the help guys. I can still return the dragonfly so we are all good.

When I bought the dragonfly it was between that and the microstreamer. Now that I am looking back at getting the microstreamer, does anyone have experience with that?

I am using a Dragonfly with my Xperia Z without problems...(with USBAPP)

I meant natively. USB audio player pro uses the special driver to communicate with dacs so it works with tas1020 also. So your nexus 5 and dragonfly doesn't work with USBAPP also?

Just because Google and the Android folk have not decided to support music lovers with proper digital outs (or decent hi-Rez DAC's) does not mean one has to suffer. The USB Audio Player folk have freed us from crappy sound. They opened the door, it is up to users to walk through it.

galaxy S4 + OTG + HiFimeDIY Sabre

 

Is there´s any idea for simultaneous DAC + charging phone - I would be so grateful. :bigsmile_face:

 

May be it´s posible with an 100K Ohm resistor across the ID/Sense (pin / pin 4) and Ground (pin 5) ? Any experience?

Okay guys, I have some pretty exciting news to share: it looks like there's a way to share external hard drives with an Android device and have the files stored on the hard drive play through USBPP and output to a USB DAC!!! I just got it working and wanted to share! (If someone has already done this before, then please excuse my excitement-- but this seems to me to be a method of getting access to vast quantities of music at high quality while on the go, and unless I've missed it this hasn't been accomplished yet). 

 

Current Setup: FLAC files on a WD 1TB external HD >>[standard USB]>> Ravpower FileHub >>[WiFi connection]>> Nexus 7 Tablet (USBPP & MobileFun) >>[micro-to-mini USB OTG cable]>> iBasso D-Zero DAC/amp >> ASG-2 IEMs

 

Basically, the Ravpower FileHub allows you to plug an external hard drive into its USB port and it will both power the drive and read its contents. The MobileFun app then allows you to access any files that are stored on the hard drive wirelessly-- which is critical for our purposes, as the USB port will be used by your DAC. At that point, after you've set up and connected the Ravpower (which takes a few minutes and isn't dead-stupid simple, but isn't super difficult), you can browse the files on the hard drive, select USBPP as the default application, and (assuming you've already plugged in and connected your USB DAC), you can play the files stored on the hard drive through your external USB DAC. 

 

As I'm a bit excited and somewhat scatterbrained at the moment, I'm going to try to break everything down into steps to make it easier: 

 

Things You'll Need

Android device compatible with USBPP

Ravpower FileHub (Amazon link)

External USB hard drive (and USB cable to connect to FileHub; I'm using a WD 1TB external HD [model WDBABM0010BBK-00], although I believe you could use any number of USB hard drives, not just this model)

External USBPP-compatible DAC

USB OTG cable for connecting DAC to Android device

USB Player Pro Android App (Play Store)

MobileFun Android App (Ravpower Site)

 

Steps

Download and install USBPP on your Android device

-Connect it to your USB DAC and ensure it can play local files from your device

Download and install MobileFun on your Android device

-Connect your FileHub to your Android device via WiFi (there is a manual that comes with the FileHub that walks you through most of it)

-Complete the setup process and make sure you're able to browse files stored on your hard drive via the MobileFun app

Open up the files you want to play in MobileFun, choose "USB Player Pro" as the media player you want to use, and voila!

 

We now have the ability to use our Android devices as media renderers and sources for terabytes of externally-stored high-resolution music while on the go, and can listen to music via pretty much any damn DAC or amp we want!!! 

 

Again, please excuse my excitement and the disorganized nature of my post-- I've just been wanting to try this for almost a month, finally got a chance to do so, and am just STOKED that it's working!! 

 

I'm going to cross-post this in the USBPP thread as well. Looking forward to seeing how it works for others!!!!

I picked one up on ebay ( UK ) from here :

 

http://www.ebay.co.uk/itm/300976195373?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

 

It took quite a while coming from Hongkong, but I've just tried it with a 320gb portable external drive attached to my tablet and it works fine. Only cost £1.35 including postage !

Hello, i bought this:

 

http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=400548410241&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

 

and i connect it my Fiio e7 (in order) then to the galaxy note 2, and when i try to listen to music, the sound come out from the phone speaker.

 

Why ?

It doesn't seems to be a USB OTG cable. You will need a OTG cable not just a standard USB cable.

damn i tought the "5pin" cable meant OTG

Thanks a lot. Relief to know that it works both dac and amp on my galaxy s3. Since people say galaxy s3 has to be rooted or something like that to enable usb audio. Now things have been clear, I guess they enabled it in the jellybean update.
