Anyone tried using the latest Nexus 7 USB Rom with the DX50?

 

http://mehrvarz.github.io/nexus-7-usbrom/

Supported USB audio devices

These are just some of the supported USB DAC's: CM106-F, FiiO E07 + E10 + E17, Hifimediy Sabre, VIA USB Audio Dongle, Behringer UFO202 + UCA202 + UCA222, Syba SD-CM-UAUD, Miditech Audioface2 (PCM 2902), FujitsuSiemens PortReplicator (CM 108), Aune T1 (TE7022), Turtle Beach Micro II, BERESFORD Caiman, Teralink x2, Headroom Total Bithead, Fostex PC-100USB.
Basically all standard USB audio devices should work.
Problems have been reported only with TAS1020B based DAC's.

 

The DX50 is not listed, but I'm trying to find a way to use it as a DAC since Ibasso is still awaiting for certification of its drivers from MSFT.

 

Apparently, the iBasso DX50 can't work with a Mac: it is not a standard USB DAC.

As far as I know, existing Android USB audio implementations are only compatible with standard USB DAC, i.e. compatible with USB Audio Class (1 or 2) standard.

 

 

Anyway, you could try to connect your DX50 with a Nexus 7 using:

 

. USB Audio Player PRO (UAPP):

UAPP includes its own USB audio soft driver.

There is a free trial version available on Google Play store

 

. the native USB audio of Android L:

Thanks for the app tip. I'll check it out

EDIT: I checked it out & the DX50 is not listed as a supported device, furthermore it seems that you can only use the UAPP native player.  My goal was to stream music from other apps using the USB audio output. I didn't want to tinker with my Rom just yet, but I may give the beta Android L a try when I have time.  
 

Thanks again

Cheers

 

Well ... I use my players on the go, so ambient noise reduced "the listening" experience.   ... important if you use on the go.

 

I think the Quality delivered by the Galaxy S5 (or any good Phone) with the E18 is great.

Wonderful, clear, great definition.

 

The AK100 II also delivers a great, great sound. Very open, great detail, great spacious sound.

 

That said, my goal was to split the functionality and have 2 compact dedicated devices.

I found that at work and on-the-go the (phone based) stack, however good or great any phone-based stack might be is not handy for me. So for me it was more about user friendliness and portability.

 

Getting to what device to use, the AK100 II is great but also expensive.

For most users I would recommend a good quality stand-alone player (be it an X3, X5 or others).

 

I chose the AK100 II because (in no particular order);

     1. Here in Belgium NO devices are on stock to test, so you purchase blind

     2. The AK100 II looks freaking awesome, and the finish is like a great Swiss watch

     3. I saw then AK100 II was new and used the same basic components as the AK240

     4. User interface is great, easy to use (custom android OS; NO Google Store or other apps possible!!)

     5. I had the budget

 

For somebody with a reasonable high budget I think I would recommend something like the X5 with its dual Micro-SD capacity and good quality.

 

 

To close ... I'm still over the moon on the E18 and it's fantastic sound quality, be it with the S5, iPOD (as AMP), iPad (DAC + AMP with camera connect kit) or on my PC's (as DAC + Headphone AMP).

The E18 delivers very good and even pushes my BeyerDynamic DT880 250 Ohm to high volume (and great sound).

 

 

I hope this can help,

Kind regards,

 

Casper

Thank you Casper. That helps a lot. I think the E18 is exactly what I am looking for.

 

I was thinking of getting a standalone DAP, but I believe the user interface, battery life, and the "all-in-one" capability of a phone coupled with a DAC is very enticing.

I found out Android L can only be tested as an emulator, not as a beta OS.  I'll have to wait for Ibasso to get MSFT driver certification for the DX50 (or Android L to be released) to finally test out the DAC function of my DX50/Nexus 7 combo.

post #5136 of 5139
Android L is supposed to support usb audio generally? I mean not only specific apps like UsbAudioPlayer?
Tha is great news...

On Android L-powered devices (i.e. on native USB audio-enabled Android devices), generic music players like Neutron, Poweramp or Spotify use the audio-specific Android interface (i.e. audio-specific framework APIs in "android.media": "MediaPlayer" class) to control playback of audio files and streams using internal DAC or external USB DAC.

http://source.android.com/devices/audio.html

 

On USB host-enabled Android devices (note: every USB audio-enabled Android device has a functional USB host feature), USB Audio Player PRO (UAPP) includes a music player and a USB audio soft driver.

The music player part of UAPP doesn't use the audio-specific Android interface.
