Ok, I found something else that is interesting.
When listening to music or Podcasts on any app (Pocket casts, Podkicker, Google Play Music, N7 player) and I initiate Google Now, it is as if it disconnets access to the file for the audio app to play the Google Now sound. The app then either continues playing without sound or the app crashes or skips the file saying it's unable to access the file (most common result).
This is with CM10.2 stable, CM11 Nightly 20131226, Supernexus 4.0 Build1.
This error does not happen on my stock Nexus 7 2012 running 4.4.2.
