Hi All,
I'm using alsa library to write an application that play and record audio
at the same time. I openned the default pcm device twice, and set params for
them, nonblock, RW_INTERLEAVED, S16_LE format, 8000Hz, and 1 channel, the
only difference is using SND_PCM_STREAM_CAPTURE for recording, and using
SND_PCM_STREAM_PLAYBACK for playing.
But the bytes played are always near half of the recorded, and the sound I
heard is slowed comparing with its normal speed.
My enviroment are:
RedHat 7.3 / alsa 0.9.0 rc5 / linux kernel 2.4.18-3
sound card module: via82xx
How can I solve this?
Thanks!
Walter
