Yes, my card was detected as an unknown card 0x11bd:0x12. I don't have 
idea how to identify correct digital_rate value for card.

I playing with a tvtime and arecord. In the tvtime I was tuned a tv 
channel and with arecord I was tryied to record some sound from TV card 
capture device.

card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 1: Bt878 [Brooktree Bt878], device 0: Bt87x Digital [Bt87x Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 1: Bt878 [Brooktree Bt878], device 1: Bt87x Analog [Bt87x Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

$ arecord -Dhw:1,1 -f S16_LE -r 119466 -d 20 /tmp/out.wav

Output file contains only wav header and 0x7fff values.

BTW, it's possible to create interconnect between sound card and capture 
device in TV card? I would like to live without cable from TV card to 
sound card line in. I was read something about dmix and dsnoop plugins, 
but i have't idea.
