Nie pamiętam czy "AVerMedia Studio" i "AVerMedia TVPhone 98" czymś się różnią ... Spróbuj z innymi wartościmi card=x (np.13) . Na podstawie powyższego widać, że karta została źle zainicjowana - wartości en i out masz na 0.
Jeśli ustawiasz ręcznie kartę to bądż konsekwetny- np.
| Code: |
options bttv card=0 radio=1 pll=1 bttv_gpio=1 bttv_debug=0 audiomux=0x20,0x21, 0x23,0x2c,0x29 gpiomask=0x3f
options tuner type=5 debug=0
|
Tylko parametry muszą być odpowiednie dla twojej karty. Ja dawno temu walcząc z niestandardową AverTVPhone (kodowanie A2) odczytałem je pod windows i po podaniu jako obcje zadziałały.
Nie zauważyłem jednej małej drobnostki - masz dzwikęk oparty o tda 9874a - może szujaj w okolicach poniższego ...
| Code: |
tvaudio.o
...
insmod args for tda9874a:
tda9874a_SIF=1/2 select sound IF input pin (1 or 2)
(default is pin 1)
tda9874a_AMSEL=0/1 auto-mute select for NICAM (default=0)
Please read note 3 below!
tda9874a_STD=n select TV sound standard (0..8):
0 - A2, B/G
1 - A2, M (Korea)
2 - A2, D/K (1)
3 - A2, D/K (2)
4 - A2, D/K (3)
5 - NICAM, I
6 - NICAM, B/G
7 - NICAM, D/K (default)
8 - NICAM, L
