Capture Repeatly Sound from ALSA

My platform is DM368.I use ALSA command "arecord -D hw:0,0 -f S32_LE -r 48000 -c 2 -d 180 -t raw test.pcm" to capture sound from the platform, the  repeatly sound data appears in the test.pcm file sometimes , and we can get log "Over run!!!..." at that time. The test.pcm is played by Cool Edit, we can hear  repeatly sound, but the duration is  shorter than 1 second.

 

We need your help.Thank you.

    Chang,

    Can you share the complete logs when you are trying this? Kill all the other media applications running in background and try to run arecord and observe the behavior. Also if you can attach the sample audio file captured, it will be helpful.
