Android phones and USB DACs - Page 177

post #2641 of 5288

Please, tell me how can I make Fiio E17 work with Xperia Neo via USB audio recorder pro. When I turn the recorder on in claims: "Failed to initialize USB device. The device was opened, but the USB stack did not configure it. This usually happens when the device consumes too much power". I turned the USB charge on Fiio off, but it still doesn't work. Can I make it work without using a powered USB-host?

According to phonearena.com, the XPeria Neo does not have USB host mode. The information on their site is not always 100% correct, so you should check again, but that can be the cause.

I actually like the form factor of the D-Zero best of all because it's so tiny, but since the Glacier was roughly the same size as my Galaxy S3, I think I liked it a touch better overall (gave me more space to rubberband to the phone without being too thick). Personally, I liked the sound of the Meier amp better, but found its ergonomics to be wanting for a mobile device (I did a review in a different thread on the comparison of the two). I haven't directly compared the Meier to the Leckerton, but I generally find them to be in the same tier in terms of audio quality and think the Leck has a shape and size that's more conducive to use with a phone than the Meier. There are more options out there to be sure, but hopefully this will give you something to research ;). 

 

@Raenmor: Anything that gets us even a half-step closer to universal compatibility between Android devices and USB DACs is a win in my book-- thanks for the work, man!! If you end up finding a way to create a service that would allow any s/w player to utilize a USB DAC, it looks like that would be pretty easy to monetize that with all the interest around this. There are a few people already working on it (most notably eXtream, who wrote the USB Audio Recorder Pro app), and whoever gets a functional version to market first stands to make a bit of money, I would imagine. Hope you keep up the work ;)

 

I would think an app that did nothing more than allow the phone to output a digital signal through  the USB port wile using any music app would be very popular. I'd pay for it.

Xperia Neo has USB host mode. It can run USB flash, mouse, keyboard etc. so it's supposed to be able to drive a USB DAC too.

Anyone else having issues with USB Audio & their Galaxy S3 in the last couple of days? My Verizon Galaxy S3 is stock (running TouchWiz). USB Audio with my ODAC has worked flawlessly for the past number of months. Updated to JB 4.1.2 (TouchWiz) a couple of weeks ago and was still working fine afterwards. In the last couple of days, when I plug in the ODAC, it states "USB device connected".. then a couple of seconds later, it says, "USB device disconnected." Very strange.

The Xperia Neo can’t probably supply the MaxPower required by the FiiO E17.

 

Configuration Descriptor:

wTotalLength:       0x00EF

bNumInterfaces:       0x03

bConfigurationValue:  0x01

iConfiguration:       0x00

bmAttributes:         0x80 (Bus Powered )

MaxPower:             0xFA (500 Ma)

 

If it is the case, you have to use a powered USB hub.

I am wondering why the  FiiO E18 is the world's first portable USB digital to analog converter / headphone amplifier for Android devices.

Is is the first Android Jelly Bean-specific USB DAC?

 

Jelly Bean-powered Android phone acting as USB peripheral > Android-specific digital USB audio out >> USB cable >> FiiO E18 acting as USB host >> headphones ?

 

 

 

 

An Android Jelly Bean-powered smartphone/tablet can have:

. an Android-specific USB audio out capability (or USB audio accessory capability), or/and
. a standard USB audio out capability (or USB audio host capability)
 
 
An Android Jelly Bean-specific USB DAC acts as a USB host, and an Android Jelly Bean smartphone/tablet acts as a USB peripheral.
The Android-specific USB DAC acts as a USB host, and provides power to the Android Jelly Bean smartphone/tablet.
 
 
A standard USB DAC compatible with PC / Mac acts as a USB peripheral, and a PC / Mac / OTG-capable Android smartphone/tablet acts as a USB host.
The USB host provides power to a bus-powered USB DAC.
The USB host doesn’t provide power to a self-powered USB DAC.
A standard ACA-capable USB DAC or an external power supply can provide power to an ACA-capable Android USB host.

Nothing to be surprise about, that's just things wearing out. Most likely your USB cable pins wearing down after multiple insertions and not making proper contact or misaligned. Try changing cables. Hopefully it's not the phone port that's worn out.

Working on it, although the music apps must specifically support it. There is no way around it on non-rooted devices.

anyone tried usb audio through xperia SP??

Also, if anyone knows, does it need micro-A or micro-B otg?

 

By Danba's gracious posts and threads i have figured out that it must be micro-B while am sure that Xperia S has micro-A or micro-AB port which in case of xperia SP is different.

 

Anywho, i have ordered otg cable from ebay, though the pin looks like micro-B but am not sure though. As soon as i get it, i 'll post here.

 

kudos to danba for everything he did for this commmunity. (The amount of work and deliberation i could only think, from head-fi to sony websites to xda all i could find is his awesome posts everywhere, almost every website that i went through for usb audio)

 

Thank you very much Daniel

 

Regards

I'd definitely be the wrong guy to ask but I remember one of the FIIO Reps named James talking about it in another thread around here somewhere.

Good suggestion.. I've used three different OTG cables (two of which are practically brand new/never used) and the issue still persists. I'm 99% positive it isn't the pins/contacts degrading since charging the phone with a USB cable works just fine. I've swabbed some deoxit onto the contacts anyways.

As far as I know, some OTG-capable smartphones, like Xperia Z, have a Micro-AB receptable; and others; like Galaxy S4 have a Micro-B receptacle.

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/2190#post_9386676

 

As Micro B receptacle accepts Micro-B plug and NOT Micro-A plug, and Micro-AB receptacle accepts both Micro-A and Micro-B plugs; a "Micro-B plugged" USB OTG cable is universal.

More precisely, a "Micro-B plug" should be a functional Micro-A plug where the ID pin is grounded.
