[FFmpeg-user] Recording sound on FreeBSD 8

My next goal is to multicast live sound. All my attemps to record
sound from a USB audio interface have resulted in a severely distorted
growl instead of normal voice. I have tried various parameters around
ffmpeg -f oss -i /dev/dsp1 -acodec libmp3lame -re -f rtp rtp://188.8.131.52:5000
or even simply
ffmpeg -f oss -i /dev/dsp1 out.wav
I suppose I need to adjust sampling rate or something like this. What
is the way to determine the correct parameters? Is there a way to
analyze the audio interface input? "cat /dev/sndstat" does not
give anything really useful.
The audio interface is not to blame because I use it all the time with
linphone for SIP calls.
TIA for any ideas.
