I'm not sure if this is due to an update or if I messed up some configuraiton file somewhere. When starting X, I used to get these log messages:

This appears to be a problem on the latest Kernel and Kernel-lts. It also seems to be an issue with the latest nvidia proprietary drivers and the beta ones.
Anybody have any ideas? Did this recently break for anyone else?

I had the same issue, I think the log messages have changed, the same info is still available in /proc/asound:
