beside galaxy lineup s3, note 2, 10.1

Can Galaxy Nexus on 4.1.1 Jellybean use DAC?

How about brand?
Sony HTC Moto LG?

This post has been edited by wkkm007: Dec 4 2012, 09:15 PM

Stock Galaxy Nexus on 4.1.1 Jelly Bean can't interwork with standard USB DAC.


As far as I know, their devices can't interwork with standard USB DAC for the time being.

U mean now galaxy lineup s3, note 2, 10.1 running on standard USB DAC?
Some can some can't like the Galaxy Note II can work with the FiiO E7. It can't operate with the CEntrance DACport LX.

I like Sony phone, Samsung design look alike only.

Done bro

The heat problem how?

Based on some dmesg log outputs, I think the Samsung USB software / firmware (Exynos SoC) is intolerant with USB DACs which are not quite conform to the USB specification.

Samsung engineers / developers should improve their USB software / firmware.
We should help them by publishing dmesg log outputs.

On the other side, USB DAC manufacturers should test their (upcoming) USB DAC with the Galaxy S3 / Note2. After all, these Android phones are best selling devices.
VentureCraft has subsequently modified the firmware and hardware of its pre mass-production Go-Dap X, which won't interwork with the Galaxy S3.

No Android 4.1 Jelly Bean-specific USB DAC is available for the time being.

About Android-specific USB audio:
"As of now, the standard Android releases do not include USB host support. Samsung decided to add this feature on their own. The Android folks are working on a funky USB dock protocol that works over USB (sort of like what Apple does) that, frankly, most of us developers think is stupid. There is certainly a push to put USB host support for standard devices (like audio, keyboards, etc.) into the normal Android releases."
[Pete Millett, design engineer from Apex Hi-Fi]

The lobbying for standard USB audio should go on.
It's on a right track thanks to Samsung.

The us$43 Samsung Galaxy S3 + Car Stereo Upgrade for WAaaY better sound quality!
http://www.head-fi.org/t/639883/the-43-gal...r-sound-quality

Galaxy S3 > digital USB audio out >> "USB OTG" cable >> Behringer UCA202 USB DAC >> car stereo amp >> car stereo speakers

"...
And so what are the results you ask?

HOLY MOLY!
Not only is the audio quality MUCH improved, but the sound is so CLEAN now. No clicks, burps, or any other weird background noises. Just straight CD quality background silence.
Even my GPS voice sounds prettier. hahah
Bass is tighter and deeper. Highs are more revealing. Everything is so much better that a novice could tell it sounds better.

And yes, GPS navigation works perfectly. If I'm listening to Pandora or an MP3 and my GPS needs to talk, then my music will go several db quieter and GPS will speak up, then afterwards the music will automatically go back to full volume.

Also, one thing I hated about Bluetooth was everytime I turned my car off for just a minute, when I would power it back on the Bluetooth would not consistently reconnect. Well, this USB-OTG has been very consistent for me so far. Music just picks back up where it left off at and is fairly quick to do so.

Cons? Well, I haven't tested hands free calling yet. But I'm told it doesn't work with this USB-OTG to DAC configuration. Maybe there is a bluetooth solution for that. I dunno? And AOSP does not yet support DACs.

Pros? Freakin everything.

Pics are below.


Here is the DAC and the USB-OTG cable:


This is how you configure the DAC.
You can probably also use the headphones output instead of the stereo RCA, but I didn't try it.


I wired up my USB-OTG cable to my iBOLT dock. It comes up through my dash defrost vents.


This is what the three connectors on the USB-OTG cable look like:


Here is the DAC being wired up. I taped up the non-used RCA's to prevent anything bugging with them.


I wrapped up the DAC with DUCT tape.
Not sure how or why the pic is sideways. It looks normal on my desktop.


Hid it behind my dash.


Here is the USB-OTG cable with my iBOLT dock.


The car stereo w/audio cable attached. Some car stereos have the 3.5mm connector in the back. Or a dual-RCA input. I'd prefer one of those to have a cleaner install. Maybe someday I'll upgrade my car stereo.


And here is the finished product. My S3 docked, charging and outputing beautiful digital music!


.." [CZ Eddie]

The heat problem of the Behringer UCA202?

I don't think there is a heat problem because the Behringer UCA202 is a DAC and not a power-hungry amplifier.

You should ask CZ Eddie. He should use his digital USB audio car stereo every day.

wow...this works on my Galaxy Nexus !!!

Galaxy Nexus > USB OTG > Fiio E10 >

I mean the battery, you charging heat from battery and the mobile phone motherboard, under the hot sun if not tinted solar car window film more hot, (online)3G cellular data the antenna hot, GPS if u on.

If charging battery while online @ home also hot till can't charge my battery(not in) if more then 40⁰c

Too hot/overheat the battery will expend and can't store charge, sometime may explode too.

If your phone has a functional USB host implemented, I think it should work with the USB Audio Recorder PRO application.
This media player application including the USB audio module communicates with the kernel USB driver thru the standard interface libusb.
http://libusb.sourceforge.net/doc/index.html

Anyway, you should ask its developer. He is active on the following forum:
http://www.head-fi.org/t/595071/android-ph...80#post_8968882

U mean 'USB host' it is USB OTG?
unfortunately no. Is to old
http://pdadb.net/index.php?m=specs&id=1967...x10i_se_rachael
http://www.qualcomm.com/snapdragon/processors/s3-s2-s1

USB is an asymmetric protocol in that one participant acts as a USB host and the other as a USB peripheral.

As the standard USB DAC is always a USB peripheral, the smartphone / tablet has to act as a USB host.

The Samsung Galaxy S3, for instance, 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 can act acts as
. a USB peripheral when a Micro-B plug is inserted in the Micro-AB receptacle of the Galaxy S3 [regular cable]
. a USB host when a Micro-A plug is inserted in the Micro-AB receptacle of the Galaxy S3 [so-called "OTG cable"]

Micro-A plug, Micro-B plug:

hey man tryin to figure out why my e10 to my galaxy nexus is coming in distorted. It is recognized by the phone using the audio recorder app but like I said when I go to play music it comes in kind of distorted, not horribly so, but enough to make it pointless. I have the stock 4.1 jelly bean rom and trinity kernel. What rom and kernel are you running? And did you change any settings on the phone? Maybe I just have a crappy OTG cable.

It’s an issue of this new app.

Workaround:
. select a wrong sample rate: for instance 48000 when playing a 44100 encoded music file
. play it some few seconds
. switch back to the right sample rate; everything should be OK from now on
