I have problem with my tv tuner (Avermedia TVPhone 98), FreeBSD 
bktr driver doesn't support my tvaudio chip :( 
(tv picture is ok, but there is no sound) 

on linux everything is ok (bttv detects TDA9840 tvaudio chip): 
Linux video capture interface: v1.00

bttv0: PLL: 28636363 => 35468950 ... ok 

but freebsd detects some odd chip (dpl3518a): 
bktr0: <BrookTree 878> mem 0xe5dfe000-0xe5dfefff irq 9 at device 
8.0 on pci0 
iicbb0: <I2C bit-banging driver> on bti2c0

iicbus1: <Philips I2C bus> on iicbb0 master-only

bktr0: Detected a DPL34-1@-@0 at 0x84 
bktr0: AVer Media TV/FM, Philips FR1216 PAL FM tuner, dpl3518a 
dolby. 
pci0: <unknown card> (vendor=0x109e, dev=0x0878) at 8.1 irq 9 

Anyone know how to solve problem with bktr driver (i'm looking 
for how-to or bktr driver description so i can add to it tda9840 
support) or where i could find other FreeBSD tv tuner drivers?
