This seems odd. In the above case ALSA drivers report that your card
doesn't support recording in 2-channel mode. This is probably not true.
Have you tried recording with arecord?

Depends on what you do. The bottom line is: use what works. For instance I
often use ALSA's OSS-emulation. It works well, and when you have a cheap
consumer card like my sb128, using the native driver interface doesn't
offer many benefits to the end user. This will probably change at some
point when there are more native ALSA utils available.
