Loaded em28xx with i2c_scan and i2c_debug and tvaudio with tda9874a
option and debug.
sudo modprobe -v em28xx i2c_scan=1 i2c_debug=1
sudo modprobe -v tvaudio tda9874a=1 debug=1
And got this ouput:

It seems to be a tda9874 there -> em28xx #0: found i2c device @ 0xb0 [tda9874]
But does tvaudio stop @ 0x160 (decimal value of 0xa0 rigth? ) and
doesn't look further?
I mean does tvaudio find my boards eeprom, cant talk to it and gives up?
