+ Say 'Y' or 'M' to include support for the PCM loopback device.
+ This module returns played samples back to the user space using
+ the standard ALSA PCM device. The devices are routed 0->1 and
+ 1->0, where first number is the playback PCM device and second
+ number is the capture device. Module creates two PCM devices and
+ configured number of substreams (see the pcm_substreams module
+ parameter).

+ The looback device allow time sychronization with an external
+ timing source using the time shift universal control (+-20%
+ of system time).
