USB Audio Tester
The app shows all detected USB devices which were present when the app was started. Each of them can be selected, and if the detection of a sound card was successful, the supported modes for audio capturing and playback are displayed, as well as (part of) the controls of this sound card.
When a certain setting for capture (or playback) is selected, the buttons for streaming audio become active. To enable the "Ext mic to ext speaker" button, however, record and playback settings must match.
"Ext mic to int speaker" captures audio from the USB sound card and plays it via Android's sound system (typically built-in speakers).
"Int mic to ext speaker" captures audio from Androids default microphone and sends it to the USB sound cards output.
"Ext mic to ext speaker" operates solely on the USB sound card, sending all captured audio right back to its output.
While one of these 3 modes is active, only the record/playback/other controls are effective. For changing sample rates, the current operation has to be stopped.
If you find a sound card that is not properly detected, please press the feedback button. The data from the USB device(s) ("descriptors") is captured in an email to help debugging the issue. If applicable, add a short description of what went wrong.
If the sound card is detected but the streaming modes do not work, try lowering the USB load by decreasing the number of ISO packets, USB buffers, or both.

What can i do with this APP?
Detects aunt, odac perfectly. Now if I could just figure out how to get other players to use the use output.
Screens are blank and there are no explanations about how it works. Useless.
It lets me pick my USB device, and recognizes the make/model, but every other screen is blank. No record settings to pick from, no playback settings, nothing...
This app works on my cheap Chinese generic android tablet The tablet has an allwinner a10 chip and the sun4i motherboard It has a kernel version by crane ..........and runs ICS 4.0.4 I used an extremely cheap USB soundcard (Chinese 50 cents on eBay) This app was able to record CD quality sound via the mic input on the USB soundcard. That's all I was hoping the app would do. The truth is that this tablet could now be used as a pro quality sound recorder by using a very high quality USB sound card
UI leaves much to be desired, but once you figure it out, it works great. Tested with a USB sound mixer on a Nexus 5
I plugged in a USB soundcard device into a Nexus 7 tablet, the app detected it, received the audio and played it to the USB speaker (actually a headset). Same with a galaxy nexus phone.
Does not detect on android tablet, will give 5 stars if you tell me how to use it.
Does what it said and played audio from a USB mic on my Galaxy nexus.
It works even if my device says that its "not" supported. :D
Force close :(
thank
Does what it says. Hook an external sound card to USB via OTG, and you test the sound with this app. Three thumbs up for having a compatible driver for the cheap card I bought. πππ
