Audio Capturing on Beagleboard

Hi Dibin,

You could start with checking whether the microphone is connected. If you not using pre-built images check if presents support of microphone and all audio settings. Could you post the whole output of the command then use dmesg -c for more detailed log.

Hi Shulev,

Thanks for the response.

My recording is working , The problem is the voice break up when ever the overrun!!!! error shows off ,

I have tried with different buffer size and period time but no use,

After some seaching i saw in a thread since the out put file is written to memory card the card write speed may low.

Now am changing the memory card to sandisk.To make sure that there is no memory card performance issue.

I will post my results here as soon as i finish this expiriment.

Dibin,

Can you try with increased buffer size?

I have the audio capture problem with beagleboard-xm(Rev-C), when I run aplay, it works well, but when I capture auidio using arecord and play it using aplay, I can only hear noise. I do not know if it is something wrong with the ALSA control settings. Can you show me your ALSA control settings?

PS: my image is linux-2.6.32  from DVSDK, and I use the headset mic.

Thank you!

Your question is not clear. Are you facing issue in arecord or aplay?
