One problem was found by using this card for capturing:

    no sound can be recorded in either TV or FM mode.

Sound works fine during real-time play. When using fxtv to save
audio into any audio format file (wav, au, aiff ...), the sound file
contains mostly 0xFx or 0x00 and some 0x01-0x03.

This card is a so-called GENERIC card, which has no manufactory name
and no any technical support information.

Can anyone tell if this is a detective card, or this is the problem for
fxtv (or bktr driver) to deal with this card?

Thanks,

    -Jin
