Hi steve,
I faced problem with record sound, can you give me some suggestion?
on my setting ,stereo, 16bit, 44100hz
now, i use madplay play music is ok.
but ,when record sound, then play it on pc. i can not hear the sound what i
play, i also hear a lot noise.
in the test code, first
open
use ioctl setting format
read data
write data in a file.
close
then play the file on pc. but i only hear noise.
i am not sure the problem is about the test code or about the oss driver.
but i am sure the setting on the aic23b is ok, for example when i setting
bypass_on,i can hear the right music.
here is my question
how to test record sound, use wavplay, any other idea?
Best Regards
alana
