This is driving me nuts. Running Win10 Pro and Mint Sylvia on a P55t-A5118. I have no problems on the Linux end, only Win 10 and that started after 1709 was installed. I have MS drivers blocked by policy. Nearly everytime I cold boot, the sound in any application is extremely low and there are no Win10 startup sounds (not that I care but just tells me I have to re-install the IDT driver). I have to re-install the driver (even though the correct one is installed when looking at device manager) to correct the problem. Upon restart, the issue is corrected. Note this only happens on a cold boot and not all the time but say 90%. Sometimes the IDT driver re-install only performs a repair, and other times it performs a complete re-install. Any suggestions would be appreciated.
