Realtek ALC889 does not work after computer wakes up from sleep.

The Realtek ALC889 sound stops working in Windows 8 RTM after resuming from S1 sleep mode, I need to disconnect and reconnect the audio cable in order to restore the sound and I have to do this every time the computer sleeps.  I'm using the latest Realtek R2.70 audio driver.  I tried the audio troubleshooter and it could not find any problems and there is nothing to fix.  The only way to fix the sound is to physically unplug the audio cable and then plug it back in and I have to do this every time I resume from sleep and this could wear out the speaker or headphone jack from repeatedly unplugging and replugging the cable.
