Apparently, the USB audio feature is enabled on factory Samsung Galaxy S III:

USB Audio
USB audio output support allows hardware vendors to build hardware such as audio docks that interface with Android devices. This functionality is also exposed with the Android Open Accessory Development Kit (ADK) to give all developers the chance to create their own hardware. http://developer.android.com/about/versions/jelly-bean.html |

The USB DAC recommended by Google is a new type of device. It is not compatible with PC or Mac.
http://developer.android.com/tools/adk/aoa...l#audio-support http://developer.android.com/tools/adk/adk2.html#play-audio  A legacy USB DAC compatible with PC / Mac acts as a USB device, and a PC / Mac acts as a USB host. A USB DAC recommended by Google acts as a USB host, and a Android smartphone / tablet acts as a USB device. Personally, I prefer the legacy USB audio feature implemented by Samsung on Galaxy S III, which can interwork with a legacy USB DAC like FiiO E7 or ODAC. The legacy USB audio feature is still specified in the Android specs: http://developer.android.com/guide/topics/.../usb/index.html http://developer.android.com/guide/topics/...y/usb/host.html http://developer.android.com/reference/and...bConstants.html "USB_CLASS_AUDIO USB class for audio devices" -------------------- Android & standard USB audio: It’s up to us!

USB-Audio support for which ADCs with Line-In or S/P-DIF Input?
Everyone is talking about USB-DACs, but what about ADC? Support for USB-Audio is good, but what USB-Soundcard with Line- or S/P-DIF-Inputs would be supported on an Android playthings? I don't want to support the Apple-Imperials and don't want to buy a Droid as long as it has no possibilities to record HiFi-stereo sound from an Line-Input. As long as this feature is not reliable implemented, for me a smartphone is not really smart as a consume-only gadget, but not a productive tool, so i still have to take my mp3-player/recorder and/or my wav-recorder with me or put my little notebook to make music. When is a Droid a real replacement for this? I heard about sc an pd on Android, but what's the use without Audio-I/O? Thanks to all peaople developing and testing on this! |

It seems Android lacks low latency audio, that's why there are no apps like garageband. http://code.google.com/p/android/issues/detail?id=3434. Some people are saying this improved with Jelly Bean, but that's to be seen yet.

An Android 4.1 Jelly Bean-powered device can have both USB audio out modes: standard USB audio out and Android-specific USB audio out.
These features are at the Android kernel level. http://developer.android.com/tools/adk/aoa...l#audio-support "Android Open Accessory Protocol 2.0 includes optional support for audio output from an Android device to an accessory. This version of the protocol supports a standard USB audio class interface that is capable of 2 channel 16-bit PCM audio with a bit rate of 44100 Khz. AOA 2.0 is currently limited to this output mode, but additional audio modes may be added in the future. To enable the audio support, the accessory must send a new USB control request: SET_AUDIO_MODE"    It should be easy to enable standard USB audio out and Android-specific USB audio out on an Android 4.1 Jelly Bean-powered device with USB host capability. Let's keep up the pressure on Google and the Android device manufacturers for the standard USB audio out: http://code.google.com/p/android/issues/de...Summary%20Stars -------------------- Android & standard USB audio: It’s up to us!

As expected, for the time being the Nexus 7 doesn't interwork with standard USB DAC like FiiO E7 or FiiO E17:

A stock Jelly Bean powered Nexus 7 should be able to interwork with an upcoming Android-specific USB audio out-capable USB DAC, like the Gear4 speaker dock, that acts a USB host (and the Nexus 7 as a USB peripheral).

The annoying thing with Google is they don't always fix even basic functionality. There's a bug in their file downloader which is usually used by all browsers which means you can't save anything that has .htaccess pwd protection in front of it. It's been open since 2008.

Well, astoundingly, the Nexus 7 doesn't support headsets (headphone+mic) over its analog 3.5mm port. It's a TRS, and not TRRS like everyone assumed and it's standard with phones and tablets now. So the only fix for this would be to use USB audio. Has anyone been successful in making an external microphone work with those DACs that have a mic input, and their Android device?
