Jaroslav Kysela 1e75673035 Introduce alsaloop utility 
alsaloop allows create a PCM loopback between a PCM capture device
and a PCM playback device.

alsaloop supports multiple soundcards, adaptive clock synchronization,
adaptive rate resampling using the samplerate library (if available in
the system). Also, mixer controls can be redirected from one card to
another (for example Master and PCM).
