Summary:                    Request to make front, rear and surround40 more flexible.
Description: 
test1.wav is a mono audio file.
aplay -Ddefault test1.wav
This produces sound on multiple speakers.
aplay -Dfront test1.wav
This produces no sound, but if test1.wav was a stereo file it would play.
aplay -Dsurround40 test1.wav
This produces no sound.

It would be nice if one selects a device that has 2 channels like "front",
and then one sets 1 channel in hw_params, alsa-lib should automatically
adjust the 1 channel to fill both output channels to the speakers.
The same with "surround40". If one sets 1 channel in hw_params, alsa-lib
should automatically adjust the 1 channel to fill all output channels.

Same problem happens with device "plug:front"

Please, could you remind me your hardware?

Note that the 'plug:front' combination should work also for mono streams.
I think that it's bug for your hardware configuration.

I have a SB Audigy 2 and an ICH5 Intel8x0.

The SB Audigy 2 fails.

The ICH5 works. (for front only, but I think getting rear to work is a
different bug)
