ok, what we found about the micronas usb headset
Bus 002 Device 002: ID 074d:3554 Micronas GmbH
can have only 16 bit mono (one channel) with arecord and dsnoop.
when we try to set U8 or S8 format for 2 channels, the chipset refuse
to do it an the software crash.
The only think working AND with cool sound we found :
arecord -f cd -t wav -c 1 -Dplug:dsp0
with
pcm.dsp0 {
type plug
slave.pcm "dsnoop"
}
(we are also working with alsa-oss)
