It requires drivers on windows to do some of the optical features, so if I had to guess I'd say yes and no. It might be able to do stereo over optical, but I doubt it would do anything like Dolby Headphone or 5.1 output. But I have an iPhone and can't test that for you. If I can get an android soon I'll give it a test run.

I am not sure to understand what type of cable you use.
 
 
A standard USB DAC like the iBasso D2 operates only as a USB peripheral. It only interworks with a USB host.
 
The Nexus 7 is a USB On-The-Go device.
A USB OTG device can act as a USB host or as a USB peripheral.
 
Simply put, a USB OTG device, like the Nexus 7, acts as
. a USB peripheral when a Micro-B plug is inserted [regular cable]
. a USB host when a Micro-A plug is inserted ["OTG cable"]
 

 

 

Nexus 7 as USB peripheral:
. Nexus 7 – regular cable – PC / Mac as USB host
. Nexus 7 – regular cable – upcoming specific Android Jelly Bean-compliant USB DAC as USB host
 
Nexus 7 as USB host:
. Nexus 7 – "OTG cable" – USB mouse as USB peripheral
. Nexus 7 – "OTG cable" – standard USB DAC as USB peripheral
 
An Android device is often connected to a USB DAC by a combination of two cables:
. OTG cable: Micro-A male to Type-A female USB cable
. regular cable provided by the USB DAC manufacturer: Type-A male to Mini-B male USB cable

Yes, according to the following post:

http://mybroadband.co.za/vb/showthread.php/429589-Samsung-Galaxy-S3?s=1a313fae4795a9a7493a6ce0f677ca8e&p=8551119&viewfull=1#post8551119

 

stock Galaxy S3 > digital USB audio out >> Asus Xonar U3 >> headphones

 

and per design:

 

stock Galaxy S3 > digital USB audio out >> Asus Xonar U3 > digital optical S/PDIF out >> S/PDIF DAC

I have a USB OTG cable which i have connected to my Nexus 7. I use this for connecting USB memory sticks with stickmount and it recognises them for access to external storage. To connect the Ibasso to the Nexus I have connected the USB OTG to the Nexus, then a USB micro B cable connected to the Ibasso. In this mode the Nexus would be working as a 'host' device? I didnt get a USB cable with my Ibasso as it was purchased secondhand.. Cheers, Mick

For anyone using an IBasso DAC with their device - how does the 'link' light behave. Does it stay on once you plug in the DAC ?

Is there any just microusb - analog line out cable ?

 

It would be cool just to use a little amp like my iBasso T3 to overcome the headphone out lack of power instead of being forced to go with a whole dac setup (much more bulkier, expensive and power hungry).

Yes, the micro A plug of the USB OTG cable should switch the Nexus 7 to the USB host mode.

I suppose you has successfully tested the iBasso D2 & the USB micro B cable with a PC.

Could you provide a dmesg output?

Apparently, a DIY USB DAC is working with a Galaxy Nexus running on a modded kernel & AOKP and AlsaMixer available on Google Play Store.

http://translate.google.fr/translate?hl=fr&sl=ja&tl=en&u=http%3A%2F%2Fdevlog.grim3lt.org%2F2012%2F10%2Fandroidgalaxys3usb-dac-galaxynexus.html

http://devlog.grim3lt.org/2012/10/androidgalaxys3usb-dac-galaxynexus.html

 

However the sound is choppy.

The AlsaMixer is likely set up to 48kHz, and his music got ripped at 44.1.
The immediate solution should be to re-rip the music at 48.
The long-term solution should be to find a way to set up the AlsaMixer to 44.1kHz.
 
 
This DIY USB DAC is also working with a stock Galaxy S III.

Thanks DanBa. Appreciated.

 

So it's a real line out and not a rerouted headphone out?

 

If so It's a shame that Fiio or some other have not come up with line out cable like the gazillion of lods that ara available for  iPods.

 

I think that just an amp would suffice for the S3.

Yes, the line out path VPS_P / VPS_N is a direct path from LINE2 L/R to MICRO USB (S/W IC) without crossing any amp.

The ODAC using the USB controller Tenor 7022 interworks with the Samsung Galaxy S3 and the Samsung Galaxy Note 2.

The ODAC has some issue with a custom Asus/Google Nexus 7.
