Good news about Android phone supports digital audio output - Page 11

post #151 of 253

The point is a 1 Ghz processor, 512 MB RAM, Wolfson WM8740 DAC, 64GB memory for music, and an Analog devices op-amp, all in a very compact phone, with 720P video, and a 5MP camera, etc... IF that setup works.

Kiteki, I don't think usb receiver based on PCM2706 is worthwhile... unless it is buffered and asynchronously clocked before fed into the DAC... I own PCM2706 converter, and it make most of the upstream DACs that I tried sounded bad... maybe except my own Monica2 DAC, which is digitally buffered and asynchronously clocked before going to the DAC chip. (by design, not a choice, TDA1545 on Monica2 use japanese EIAJ format and thus standard I2S must be converted first)

That is useful info, makasih.

sama-sama... BTW I want to know your impression on FXD80 :) that leather case is very tempting... but Tenso don't ship to Indonesia...

what about Samsung Galaxy Player 4.0 and 5.0 which are exclusively for music listening?

 

Those should enable usb out as well :(

The USB Audio host mode is specified in Android specifications:

http://developer.android.com/guide/topics/connectivity/usb/index.html

http://developer.android.com/guide/topics/connectivity/usb/host.html

http://developer.android.com/reference/android/hardware/usb/UsbConstants.html

"int USB_CLASS_AUDIO USB class for audio devices."

The standard USB audio module is present in the kernel source code of the Android 4.0 Ice Cream Sandwich powered Galaxy Nexus. It is not included in the stock binary kernel of the 4.0 Galaxy Nexus.

Very likely, the standard USB audio module, including a new control request, is present in the kernel source code of the Android 4.1 Jelly Bean powered Galaxy Nexus; and it is included in the stock binary kernel of the 4.1 Galaxy Nexus.

 
"Android Open Accessory Protocol 2.0 includes optional support for audio output from an Android device to an accessory. This version of the protocol supports a standard USB audio class interface that is capable of 2 channel 16-bit PCM audio with a bit rate of 44100 Khz. AOA 2.0 is currently limited to this output mode, but additional audio modes may be added in the future.
To enable the audio support, the accessory must send a new USB control request: SET_AUDIO_MODE"
 
Hence, a 4.1 Android device can support the USB audio host mode and the USB audio client mode.

Hopefully, Google and Android device manufacturers will enable the USB audio host mode along with the USB audio client mode on their stock 4.1 Android devices. It should be available to everyone, and not only for a few ones hacking their Android device.

 

One of the ways to let them know that is to vote for the Google issue "Enable (standard) USB audio":

http://code.google.com/p/android/issues/detail?id=24614&sort=-stars&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

 

And please ask around.

I was looking for a way to output my Galaxy note with USB audio and came across this forum.

 

Very exciting news that Jellybean supports USB audio. 

 

I will have Fiio E17 by monday and install a test Jellybean SDK and see if it will do the magic.

The SDK is very bare bones Jelly bean. I doubt it includes the audio drivers. You'll need to install a proper jelly bean rom.

if it works with jelly bean or the new samsung galaxy players thaa a definite buy for me and win for android/fiio!

post #162 of 253

I can't believe we still don't have confirmation on whether Jelly Bean works with the Fiio E17. Is there not one person out there who owns either the Nexus 7 or Galaxy Nexus with JB and a Fiio E17?

its new.would take a while

post #164 of 253

I asked this question on anther thread but realize this might be a better place to ask this question.

 

I have an AT&T Galaxy SIII and I am looking for a portable DAC/AMP unit to use with it.

 

I read that most DAC's that use TI2706 USB receiver will work with the SIII and I just want to see if anyone here had successfully used the iBasso D-Zero (uses PCM2706) with the SIII.

 

I am trying to decide whether to buy the Fiio E7 or the iBasso D-Zero.

 

Thanks
