[...] 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.
There is a datasheet for these chips, so writing some code for this should be easy. However, the I2C controller is not managed by the snd-bt87x driver but by the bttv driver.
Old linux drivers (no longer compile on suse, or fedora) should help:

Now that we know the GPIO settings, how hard is it to add i2c support in bttv?
