+; Default mapping only allows to use stereo input and sound card has two
+; physical input channels.
+;
+; However in case of only using a single input channel (like condenser
+; microphone) only one channel will have any sound, which is often
+; inconvenient for casual use.
+;
+; This config includes mono input options which makes it much more
+; friendly in single input configuration.
+;
+; This config also removes default digital input/output mappings that do
+; not physically exist on this card.
