[pulseaudio-discuss] [PATCH 2/2] loopback: Reset sink input rate when source or sink changes

[Georg Chini]

If source or sink are changed, the current sink input rate may be different
from the default rate. Switch sink input rate back to default to avoid the
influence of the previous combination of source and sink.
