Shoot the Trouble -- USB Audio Interfaces

With all the very interesting Raspberry Pis and other ARM devices around, Linux becomes more and more interesting for many people. Great audio transports can be build at 100$.
Not to forget. Tablet and Phones are mainly Androids and that is just another Linux, using the same soundlayer (Alsa) then all other Linuxes.

Manufacturers usually still do not commit to support Linux or Android properly.
Which is insane. The vast majority of mobile device out there are Androids.

However. Many devices work or partially work under Linux, because manufacturers comply to general USB Audio Standards (UAC1/UAC2). Meanwhile even Pro Audio companies like RME offer a "Class Compliant" mode for their newest generation of USB devices. (In the RME case they do officially focus on OSX though.)

Anyhow. Even though things are getting better, there are still plenty of  cases where you'll experience NO SOUND.

That doesn't necessarily mean that your device won't work under Linux.

This article outlines a little guideline for troubleshooting your USB audio interface under Linux.
It should give you certain hints what to look for.

However. Just to make it clear from the very beginning.

I won't support anybody, who got issues with his interface!!! Checkout Google or the community.
