Hi,
I am not a member of the list. Please cc me in responses.
i have the leadtek winfast tv2000xp expert tv card. it uses the cx8800/xx drivers. the sound is going through the cd channel.
when i install a v4 kernel, there is a screeching sound about the time
it seems the modules get loaded during the boot process. this doesn't
happen on the v3.17 kernel i am currently running. interestingly when i
open tvtime in the 4.x kernel the screeching sound stops.but tvtime does
not pickup the audio from the tv line. it just has a shhhhhhhhh sound.
when i blacklist these modules on the 4.x kernel, the screeching sound doesn't happen.
the screeching sound -
