EM2860 + SAA7113 + STAC9752 no have sound

Hi!

I have the EasyCap device with EM2860 + SAA7113 + STAC9752 chips. Video from composite and from S-Video operate great.
But I not have the sound. I do not see any errors in my logs. I tried VLC and gstreamer for open alsa device with any rates and options.

I work on Ubuntu 12.04 and tried 3.2, 3.11 and 3.13 kernels.

This is operate great if before connect devices I execute:

sudo rmmod em28xx_rc
sudo rmmod em28xx
sudo modprobe em28xx card=2,2,2,2
