Subject: Can't set less than 48k rate in the Intel-ICH4 (AD1981B)

Hi,
In my case,
Alsa prepares 4 pcm devices,
and I use the first 0-0 and the 4th 0-3, each playback and capture.
But when I set to the 3rd less than 48k rate,
Alsa shows error,"cannot set sample rate".
On the other way,
the 1st can be set less than 48k rate as a capture port.
Playback use is no problem.
The Intel ICH4 in my laptop TP/R50e seems to have Analog Devices AD1981B as AC'97 Codec, alsamixr says.
AD1981 spec sheet
http://www.analog.com/en/prod/0,2877,AD1981B,00.html
With the "PCM ADC RATE REGISTER" in the spec sheet,
we can be supported of from 7k to 48k rate.
What does Alsa do for that?
Does anyone knows ?
Thanks,
Junji
