With big struggle i installed my tv card (pixelview playtv pro ultra) connected by cable to linein input in my sb live 5.1 soundcard with commands:
sudo rmmod tuner
sudo rmmod cx8800
sudo rmmod cx88xx
sudo modprobe cx88xx card=12 tuner=28 i2c_scan=1 (no sound with card=27)
sudo modprobe cx8800.
Everything was ok until i pressed record button in fm-radio application installed from synaptic. After this everytime i use those commands i hear sound from my tv card not only in linein but also in pcm output in alsa mixer.
I've no idea what happend and what to do to disable "this feature" in my cassandra. Please help, i'm newbie in linux!!!
