Is every BT878 card able to send the sound via the pci bus? I always wondered what the multimedia device at 6.1 is. bktr0: <BrookTree 878> mem 0xca000000-0xca000fff irq 16 at device 6.0 on pci5 bktr0: [GIANT-LOCKED] bktr0: Hauppauge Model 61324 D229 bktr0: Detected a MSP3415D-A2 at 0x80 bktr0: Hauppauge WinCast/TV, Philips PAL I tuner, msp3400c stereo, remote control. pci5: <multimedia> at device 6.1 (no driver attached) -- Bye Frank
