I have an AF9035 based stick with that chip and once sniffed the communication from cold state until about the 40th frame. At that point what appears to be sound frames in the iso packets still just contains 0x00 bytes at about 192kB/s. VBI data is captured as well raw and sliced but I don't know if the slicing is done by the AF9035. I beat the old log into a shape similar to your log's and uploaded it: http://pastebin.com/mfN1TXrG AF9035 firmare and iso data have been omitted. As you can see, the driver uploads some kind of firmware to the upper address space of the AVF4910B. According to http://driveragent.com/c/archive/562634f6/image/2-1-0/Yuan-MC270B-TV-Tuner-Driver,-IdeaCentre-B310 the chip contains a 8051 microcontroller. Devin Heitmueller once told me that he wrote a driver for the AVF4910A as part of their Osprey 240e/450e driver. He also said that it was completely different to the AVF4910B. I can no longer find it online, but my local copy tells me that the AVF4910A also uses demod register 0x50 for I2S configuration and register 0x20 for standard selection. Maybe they are not so different after all.
