Ok. Do we know which devices this applies to? I'm thinking of getting a Galaxy S3 but it's a bit expensive and bulky.

But the USB Audio Recorder Pro app is very limited in its playback features. You can only manually select one song at a time, and then either hit play to replay that one song,  or go search for another song to listen to.

Does anyone know if the Samsung music players work with external usb such as this one:

since some of their phones work, I wonder if their Android pmp's work also.

 

Edit: I see they have a new 5.8 inch model that has Android 4.0....but it would have to be a great price to compete with the tablets out there now.

What was the original question to Supercurio?  His response looks a bit harsh considering those of us who are just trying to improve the sound not making any statements of this being the best sounding with these portable/budget dac/amps.  And funny that he did so much work on the Galaxy S series with Voodoo sound but never released anything for the S3 Int'l.  Apparently, Samsung did a good enough job on implementation so there was no need for a Voodoo tweak is what I remember reading somewhere.

Here's the whole conversation (still waiting for a second reply but i doubt I'll get one...)

Hi there!
I've been hearing a lot about your amazing work with the Wolfson audio chips and I'm waiting patiently for "Voodoo Sound" to be updated. I have one question though, will you implement USB audio with the update or is that something for the future? Specifically the ability to use an usb DAC with the phone. This was possible on stock ICS and on Cyanogenmod 9 but sadly not on any other version of Android, custom or stock.
 
Here's a great thread where DanBa amongst others have explained the usb audio functionality for others and there's also a list of handsets/tablets that can work with different DAC's
 
Thread: http://www.head-fi.org/t/595071/android-phones-and-usb-dacs

List (now updated with handsets working with an app that someone discovered, called USB Audio Recorder):

I know that you're probably wondering why I (and others) don't downgrade to stock ICS or CM9. I think the reason is that with all the new features and improvements that Jelly Bean brought, it's simply not worth going back to ICS just for the ability to use a DAC with one's phone.
 
If it helps I'm currently on CM10.1 (Android 4.2.1) latest nightly and with a DAC that's compatible connected the phone actually recognizes the usb device as an USB DAC but produces no sound. I used "dmesg" in the android terminal.
 
Finally, thanks for your time and I hope you didn't find this e-mail annoying. Keep up the good work!
 
Regards

Hello Joseph and thanks for your interesting email.

I don't plan to investigate on USB DAC so far because the portables one I know available on market are of poor quality.

A few months ago I bought a FiiO E17 in this purpose and it turned out to be an overhyped crap (I should have known better) so as it's considered as the best on market by many it showed me it's much more interesting to focus on quality low power DAC/Amp inside devices already.

Working on a solution that would lead most to get worse audio quality, bulk, no audio in calls, added complexity for charging, physical damage of the smartphone casing if both are in the same pocket without even more bulk.. Well I can continue the list. Oh and cost! That makes absolutely no sense to me.

If you know of portable USB DAC+Amp worth it please let me know!

Well, I don't have any experience with FiiO products but I've heard that they are worth the price, it is after all a portable solution and one can't expect hi-fi quality. However, am I not correct when I say that the DAC in external Dac/Amp combos are better than that of the GT-i9300? Otherwise the S3 would be godlike if its dac could outmatch external ones.

I got an iBasso D-zero for Christmas and I'm really satisfied with it, both the amp/dac is far better than my Macbook and improves the sound significantly. I've only had the opportunity to use use the amp section with my phone and even then the sound clears up, especially with <40 Ohm impedance phones.
Another great plus is the size, it's tiny!

May I ask what kind of headphones you were using? Because the benefit of an amp really depends on how difficult they are to drive, i.e impedance.

Anyway, thanks for the reply, it's a shame that you won't investigate into the usb audio functionality as i don't think I would be THAT hard considering that the phone already recognizes the device as an usb dac, not that I would know, just a guess.

PS. I got the iBasso from their website for about 100 dollars, It's worth a try!
DS.

Regards

EDIT: I actually did downgrade to CM9 (ICS) but I still can't use my USB dac, just a heads up for those who consider downgrading. Haven't tried stock though.

According to the USB specification, Micro-A plug and Micro-B plug should have different shape. 
 
But the key stuff is that for USB host / USB peripheral role switching purpose, the OTG Android device senses only the ID pin which is grounded (i.e. pin 4 aka ID pin connected to pin 5 aka GND pin) on all Micro-A plugs  and floats on all Micro-B ones
 
If it is not the case, Lindy should not advertise it as a Micro-A plug.

Standard USB audio is enabled on stock ICS-powered S3 as well as on stock Jelly Bean-powered S3.

 

It was also enabled on some early release of CM10 according to the following post:

http://forum.xda-developers.com/showthread.php?p=29691769&highlight=usb+audio#post29691769

 

"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?"

He could use a cheap standard USB DAC which interworks with the stock S3:

Hi guys, 

 

So I been trying to read through this thread, but since its 87 pages, whats the conclusion? Can I use a Galaxy Note through an external/portable DAC through the micro USB of the Samsung device at this point, or is it still work in progress?

I have a Note 1 also. I think the answer is, you can't do it with Samsung firmware and you can't do it with Cyanogenmod or other mods right now. And AFAIK no coders have signed up for this. The hardware could do it but nobody can be arsed to integrate the kernel drivers into the software. 

 

However, if you can live with just the one piece of software, this should work https://play.google.com/store/apps/details?id=com.extreamsd.usbaudiorecorderpro  By all means try the TRIAL version first to see if your device works:

http://www.audio-evolution.com/downloads/USBAudioRecorderPROTrial_1.0.2.apk Please have a look here for a list of tested devices before purchase: http://www.extreamsd.com/USBAudioRecorderPRO 

 

OK wait, he says Note 1 doesn't work. And the developer OWNS a Note 1. Might be worth contacting him for details. He might have said Samsung deliberately crippled him on those devices. There is a chance that say, cyanogenmod + USBAudioRecorderPRO would work. I've been waiting for a stable build http://get.cm/?device=n7000 and also for my cables to arrive.

Damn this is bad news. I mean if it means I have to get a Note 2 for USB Audio to work, its a let down.. It literally makes portable USB DAC/AMPs useless, does not it? 

 

Did you look into custom ROM to make this work? If they say the hardware supports it, it should be a matter of upgrading the OS to make it work, technically...

I'm happy to be corrected in any of this, but... I don't see the Note 2 as bad news. It should work right out of the box. Just need a USB OTG micro cable and a DAC. Don't need firmware mod, don't need USBAudioRecorderPRO The bad news was for Note 1. There is an outside chance Note 1 can work if you put BOTH cyanogenmod AND USBAudioRecorderPRO but nobody has tested that yet.
