Same exact symptoms on my gigabyte P35x v4. I fiddled around with audio settings forever before I found (from this thread) that I could mute and raise the volume from there. At least it is workable for now but I subscribed to this bug.

The sound icon in the desktop sound settings does not appear muted and toggling the mute setting does not restore the speaker audio. *However* I can restore speaker audio by muting the audio and then increasing the audio volume from a muted state. This works when using the audio function keys on my laptop, I haven't tried achieving the same thing through the GUI. Strangely simply toggling mute doesn't restore speaker audio, neither does just fiddling with volume, I have to increase the volume from a muted state. Additionally headphone audio doesn't appear to have any problems, it continues to work after a suspend.
