This card does not use analog bt878a inputs, but rather the digital input. To get audio working I set the mask to 000303, first two bits are for the audio rate, 00 is 32000, 01 is 41000, 10 is 4800. The first two bits in the next byte are for balanced or unbalanced audio input. 0x00 for unbalanced and 0x100 for balanced. So I am using:

modprobe bttv card=140 bttv_gpio=1 bttv_verbose=2 bttv_debug=1 gpiomask=0x020303 audioall=0xFFFDFC

bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:08:04.0, irq: 24, latency: 132, mmio: 0xc8600000 bttv0: detected: Osprey-440 [card=140], PCI subsystem ID is 0070:ff07 bttv0: using: Osprey 440 [card=140,insmod option] bttv0: gpio config override: mask=0x20303, mux=0xfffdfc,0xfffdfc,0xfffdfc,0xfffdfc bttv0: gpio: en=00000000, out=00000000 in=00feffff [pre-init] bttv0: risc main @ 37f25000 bttv0: gpio: en=00000000, out=00000000 in=00feffff [init] bttv0: BT878A ARESET bttv0: tveeprom i2c attach [addr=0x50,client=tveeprom] bttv0: using tuner=-1 bttv0: i2c: checking for TDA9887 @ 0x86... not found bttv0: registered device video0 bttv0: registered device vbi0 bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] bttv0: video mux: input=0 mux=2 bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] bttv0: PLL: 28636363 => 35468950 .<7>bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] ok

So the issue now is that the audio is WAY to high so it is very distorted. The audio is controlled via X9221A chips on the i2c bus at 0x50, there are not drivers for X9221 so I can't lower the audio levels. Anyone able to help me with this last part???
