It's not directly related to this message, but in 3.0 the Realtek HDA driver was changed to implement auto-mute. For example, if something is plugged into the headphone socket then speaker output (assumed to be line-out) should be muted. Depending on the board configuration, other auto-muting may occur. You may need to disable this feature. Ben.
