I expect to work on hw:1,1.

I tested arecoed and aply.

arecord -D hw:1,0 -f cd zzz.wav --->erre message:"ALSA lib pcm_hw.c: 
1155:(snd_pcm_hw_open) open /dev/snd/pcmC1D0c failed"
arecord -D hw:1,1 -f cd zzz.wav --->fine
aplay -D hw:1,0 zzz.wav --->fine
aplay -D hw:1,1 zzz.wav --->not to play sound. (silent)

I can not figure out to use same hw.
