Alsarecord using USB mic
I want to record audio using my USB mic.
Following is the procedure I have followed.
1. alsamixer -c 1 -> Increase the volume by pressing Up arrow in 'Mic' field.
2. arecord -f cd -d 10 -t raw -D hw:1,0 -c 1 | lame -x -r - dev1.mp3
Since my h/w is detected as device 1, I have given hw:1,0
-c 1 -> no. of channels..If I dont give this option or If I give any other parameter(say 2,3etc) record is not proceeding. It is taking only 1 as the parameter.
Once I have done this it is able to create the file dev1.mp3. But when I play this file nothing is audible.
Can any one suggest the right procedure to enable the USB mic and record the audio.
Thanks in advance
