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).
