I also have a no sound problem under F 7 with intel-hda-audio (Gigabyte DS3 rev 3.3 MB integrated audio) which seems to have started happening after an update a few days ago, but not until I did a cold boot.
I get this error:
"Sound server informational message: Error while initializing the sound driver: device: default can't be opened for playback (No such file or directory) The sound server will continue, using the null output device."

The first time this happened yesterday a warm reboot fixed it. I'm not sure how to diagnose whether this is a hardware problem, or a Linux problem...
