sky god said that you could test these command

aplay -D hw:0,0 audio_sample.wav  //from 3.5 hole
arecord -d 10 -f S16_LE -D plughw:0,0 test.wav //record by mic

with the help of sinovoip,i have solved the problem（but only include the headset,I will try to solve MIC problem）. First,you should write these command to the file of /etc/rc.d/rc.local,The most important is that in the rc.local,you must change the top file from #!/bin/sh to #!/bin/sh -x. The commands are

rm -f /usr/share/icons/hicolor/scalable/apps/libreoffice-*.svg || true rm -f /usr/share/applications/squeak.desktop || true

/usr/sbin/alsactl restore
