[alsa-devel] save alsa buffer

Hi,

I am trying to save content of alsa buffer to file for playing it in Matlab.I choose Matlab for prototyping. I run full duplex ALSA based on code from http://www.bel.fi/~alankila/blog/2005/08/21/Full Duplex ALSA.htmlhttp://www.bel.fi/%7Ealankila/blog/2005/08/21/Full%20Duplex%20ALSA.html

I run alsa on Beagleboard. I want to save buffer content to a file, but it failed with error: Segmentation fault when reach fclose(fp). I want to know what kind of data that ALSA processes so I can implement my LPC vocoder.

Thank you.

Best regards,

Arif
