Android phones and USB DACs - Page 48

post #706 of 5369

Thanks Danba.  I bought the phone to be my phone, and had no intention to use it for music, though the flac compatibility was a selling point.  I use a Cowon x7 as my main music player, and it compares favorably with the sound of the Samsung - different flavor, equal quality...  With the HRT Headstreamer, the Sammy sounds better.  So, it would be nice to be able to pull files from a flash drive, or even a small portable USB spinner, while playing the the Headstreamer, and not draining the battery of the phone in case i actually hve to make a call!!!!

 

I may tr to order some stuff via Amazon, and will keep you posted...

 

keep those cards and letter coming!!!

You may also add more internal storage memory to your Galaxy S3, perhaps a 64GB microSDXC card:

Hopefully, you will test your Galaxy S3 with all the USB DAC available at Music Direct.

Also, I am wondering if Music Direct will provide short USB cables to connect an (Android) OTG device like the Galaxy S3 to a USB DAC (i.e. micro-A to micro-B/mini-B/type-B USB cable).

For the time being, some creativity is needed to connect a Galaxy S3 to an Apex Glacier USB DAC/amp:

Hmmm...I put this pix up in the Apex Glacier thread :-

http://www.head-fi.org/t/632019/apex-glacier-amp-dac-review-and-appreciation-thread/75#post_8814974

 

And I'm sure it's probably the same connection but laid out that way, it looks much less messy than the above.

Regarding my earlier post about contacting feiao from Fiio about a short micro-usb cable, I did get a reply stating that they have one in the works.

post #710 of 5369

OH? that is pretty nice, I hope they got note 2 support soon too, So I can assemble my audio kit using various cases and velcros

I just switch from iPhones to the Galaxy S3; I'm not familiar with different Android mods.


"Since flashing KERNEL-CM-10-20120801 | Audiopatch for 10-20120801 & Camerapatch for CM10-20120801 yesterday, the USB Audio driver appears to have vanished (was working after flashing just the 10-20120801-EXPERIMENTAL-i9300-CODEWORKX build)
 
I've flashed today's build with a full wipe, and its the same story, the X360 controller and USB HDD still work fine, but no USB Audio, My guess is that it was removed from the kernel?"

Interesting, but disappointing. I wonder where it went... We need to clamor for genuine CM10 support, I think.

Would this simple OTG cable work better? Only 5 bucks with worldwide free shipping

So I found this thread that led me to a CM10 patch that was submitted on October 23rd and has been in review for the last week and a half and has several code review signoffs. Could it be that we'll see it in a CM10 nightly any day now!?

So does USB audio work with the Nexus 7? I'm thinking about running a transportable setup like this if possible...

 

Nexus > OTG > USB hub + HDD > USB DAC > AMP > Headphones

post #716 of 5369

HI DanBa,

 

I tried the Terminal emulator but no luck as it kept giving me an error. Anyother method to do it?
 

When the DB2 is connected to the S3, the songs seem to forward in big blocks. The moment you hit play, it jumps to 50 seconds, then jumps to 1 minute 40 seconds and so on.

 

An entire track is finished in 5 seconds and it jumps to the next track.

post #717 of 5369

Using the Terminal Emulator won’t fix the error.

It just provides a log file which should list the normal or errored messages exchanged between the smartphone and the USB DAC.

Yes, with a custom kernel.

 

 

 

 

A list of standard USB DAC reportedly interworking with a custom Android-powered tablet Asus/Google Nexus 7:

 

custom Google Nexus 7 > digital USB audio out >> USB OTG cable (micro-A plug inserted in the Nexus 7) >> standard USB DAC >> amp >> headphones

It requires a modified kernel. There is a thread here with a guide on how to do it.

It won't work with a standard USB DAC according to its description:

"This Micro USB to Mini USB 2.0 Adapter features a Micro USB male (B-type) connector and a Mini USB male connector.

Connectors: USB mini A male, Micro-B male"

 

 

In standard USB audio, a PC / Mac / Galaxy S3 / Galaxy Note 2 / Nexus 7 operating as a USB host (i.e. a USB A-device) interworks with a USB DAC operating as a USB peripheral (i.e. a USB B-device).
 
The Galaxy S3 / Galaxy Note 2 / 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 a Galaxy S3 / Galaxy Note 2 / Nexus 7 can act 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"]
