To set the playing sampling rate to 11025, you can use
audioctl -w play.sample_rate=11025
To set all of the play parameters for CD-quality audio, you can use
audioctl -w play=44100,2,16,slinear_le
Note that many of the variables that can be inspected and changed with
audioctl are reset when
/dev/audio0 is opened. This can be circumvented by using
/dev/sound0 instead.
