[linux-audio-dev] Usb audio problem

Hi all,
I am trying to record audio from my STM webcam the driver for it's sound card's driver is loaded automatically as snd-usb-audio.
But When I try to record through sound recorder, it did't record anything.
On seeing at the catc traces I came to know that the sound recorder even don't set the streaming alternates.
Any suggestions?

Best Regards
