changing sample rate for webcam microphone

[malte.gell@xxxxxx (Malte Gell)]

Hello,

I have to change the sample rate for my USB webcam microphone in order to use 
it. So far I used ALSA:

pcm.usbmic {
        type rate
        slave {
                pcm "hw:1,0"
                rate 16000
        }
        converter "samplerate_best"
}

Which gives me a device "usbmic".

How do I achieve the same with pulse audio, so I can use the webcam mic with 
pulse?

Thanx
Malte
