Its main goal is to address the long-standing issues wrt the implicit feedback mode. With the current driver, when the implicit fb is used, the full duplex doesn't work properly unless you start both streams *very* carefully. This patch set tries to ease such the configuration mismatch and fix many other bugs. In short, with this patch set applied, USB-audio driver will try to restrict the hw_params to match with the already opened counter-part stream automatically. So individual aplay and arecord invocation should work now, as well as PulseAudio. Also, the patch set includes more fixes, e.g. the generic detection of the implicit feedback mode on UAC2/3, and the fix for the sample rate selection on UAC2/3, as well as a few more quirks to follow the new implicit fb model. The latest patches are available in topic/usb-audio-refactoring branch. I specially thank Keith Milner and Dylan Robinson for their time spent for lots of testing. Without their patient help, I couldn't finish those patches, as I myself don't own such devices.
