Asus T100HA battery drain in sleep because of Intel SST Audio Device?

Hello all!

As the subject says, I am having an issue with the battery draining when the tablet is in sleep mode. For example: if the tablet is in sleep and the battery is at 90% when I use it an hour or two later it will be down to 60-ish %. I ran "powercfg/energy" to see what was going on and found that "Intel SST Audio Device (WDM)" was preventing the tablet from truly sleeping.

My question is if there is any way to fix the driver. I have tried updating the driver and overriding the driver in the cmd mode. The only thing that prevents it from draining is completely disabling the driver through the device manager, but this has the adverse affect of no audio. I know there are threads out there saying that you have to mute or set the volume to 0 before you put the tablet to sleep but that hasn't worked for me either.

Thanks in advance
