Olá mstr!
Com o comando
modprobe msp3400
parece que o som é inicializado corretamente, mas não tem saída alguma.
Depois:
# lsmod | grep 3400
msp3400 31648 0
i2c_core 22656 6 tuner,bttv,i2c_algo_bit,tveeprom,msp3400,i2c_ec
v4l2_common 25216 4 tuner,bttv,videodev,msp3400
e também
# dmesg | grep tv

Então, parece que o módulo msp3400 está sendo levantado sim.
Alguma sugestão?
Obrigado!
