Hi! I got a problem with my Hauppauge WinTV Theater card under Linux. The problem seems to be caused by IRQ sharing. First I had my card assigned to IRQ 5 together with my SCSI controller. I assigned my TV card to a free IRQ, IRQ 11, in the bios. Although now cat /proc/interrupts doesn't show any more sharing, ksysctrl tells me that IRQ 11 is shared by my Brooktree chip - Audio device and my Brooktree chip - video device! To give you an idea, here's what harddrake (hardware detection program under Linux Mandrake) tells me exactly: "Brooktree Corporation" MODEL="Bt878" TYPE="tvcard" BUS="PCI" MODULE="bttv" POS="0" ID="109e036e" "Brooktree Corporation" MODEL="Bt878" TYPE="tvcard" BUS="PCI" MODULE="bttv" POS="0" ID="109e0878" (twice Brooktree, bttv) Therefore I think I can't achieve to have a valuable result under for example kwintv (I only get a local TV channel, in black and white, without any sound; I even think that that my card receives the channel without the cable (antenna) but directly) Anyone having a good advice? Alex ---- P.S. I'm using Linux Mandrake 7.2, kernel 2.2.17. My card works without any problem under Win98.
