For my Hercules Smart TV card sound also disappeared after 2.6.29
with the message:"bttv0: audio absent, no audio device found!"
I have bisected the problem to commit 859f0277a6c3ba59b0a5a1eb183f8f6ce661a95d:
 "bttv: convert to v4l2_subdev since i2c autoprobing will disappear"
If I revert this everything works again
