Re: [linux-dvb] TeVii S470 Tunning Issue (Kernel 2.6.27-21)

[Hans Houwaard <hans@ginder.xs4all.nl>]

I don't really know why, but it happens sometimes on my machine with the 
same card as well. When I have problems, I power off the computer and 
then restart it again. The card will not properly load or function 
untill I do. There is probably some hardware lock that needs to be reset 
by powering off the card.

The loading of the firmware sometimes takes a couple of seconds in my 
machine, it's not very fast. Besides check if the card, which is on a 
PCI-1x slot, doesn't share an IRQ with the onboard soundcard. That will 
seriously effect the performance of both the card and the sound.

Good luck,

Hans
