Good news about Android phone supports digital audio output - Page 12

post #166 of 253

Thanks for the links. I read that thread and it seems that the member you were quoting was using iBasso DAC/Amp but he did not state which particular he was using. Do all iBasso DAC/Amps uses TI pcm2706's thus will work with Galaxy SIII? 

 

I just want to make sure just in case iBasso uses different USB receivers on their portable line of DAC/Amp like what Fiio.

 

I have also sent an inquiry to iBasso so let's see what have to say on that.

 

Thanks again for your help.

It doesn't work, as far as i can tell.  I tried hooking up my E17 using a usb-otg cable to my Galaxy Nexus running Jelly Bean and it outputs through the external speakers like normal.

So, did I get that right: no usb audio out on Galaxy s2 yet, and probably it'll never be?

So there is NO was to improve the galays s2's Sundquality?

we already start develop a portable dac for Android phone which is total selfpowered.

Good idea, because as I have learn't USB power is dodgey, Look at the ODAC how its performance varies from the bad quality power it gets from PC and Mobile usb ports, and then the 100mW max draw most devices have. 

 

External is the way to go, and by making different "covers" one device can be used with many different phones, by just changing the cover, or not even using it, vs the VAMP which is locked to the iPhone 4/4S.

Any idea when it will be available?

Just bought a LG P920 Optimus 3D from a local clearance sale.

Sadly, the Optimus 3D doesn't seem to support USB-OTG and an official update for Jelly Bean is due the lacking success of the series very unlikely.

 

Anyhow, is there any chance, that USB-Audio might work someday or is USB OTG absolutely necessary?

Read some more into this thread and you will see you need 3 components:

  1. ALSA Drivers at kernel level
  2. USB Host (included OTG)
  3. and something elese that slipped my mind, I wrote it somewhere in here.

 

look here for custom roms that may support it

Thanks for your link, it will be helpful to get some more informations.

From the specs, it seems that the processor of the Optimus 3D (OMAP4430) supports USB-OTG, but unfortunately the kernel doesn't.

most current android phones support otg

Its just kernel not doing the trick. XDA is developing some kernels that allows you to do that. (some phones only)

You will need to ask Kernel devs to implement it, which is easier said then done, XDA-devs are notorious for ignoring requests, simply because they only really post their work there, they don't go there to take requests.

well you dont have to take that negetive

they are not doing it for any profit. Its just their hard time spent to share with the world.

If one rom doesnt suit you use the other. 

 

Plus they can only do things they are capable of. Have you imagined how many requests of 'do this' 'do that' they receive a day?

I'm a developer myself, I'm not being negative, its just a fact, they don't take requests for that very reason.

Thanks for your opinions. For me as a android-newbie, the whole mod-theme is quite complex and not easy to see through.

But the possibilities are indeed interesting.

 

At Head-Fi, are there any reports of modded android smartphones that work with a usb-dac?

(I've read only about the stock Galaxy S3, some tablets and the Nokia N8 with Symbian OS)
