Subject: arecord wav file, buffer different
Date: Sat, 17 Apr 2004 16:06:01 -0500	[thread overview]

I all,

I have some problem writing an ALSA driver:

When i use arecord:
arecord -d 10 -r 8000 -f S16_LE -t wav -c 1 test.wav

the data area of the wav file (test.wav) is filled with 0.
I compared the data of the wav file and the data of the capture buffer:
They are different, the buffer is filled with audio datas.

Why my test.wav file is filed with zero?

Any ideas?

Thanks in advance.

regards,
Mahtieu
