This is an ongoing problem. I'm on a MSI GT72VR 6RE which uses the realtek version of Nahimic.
I just recently installed the driver listed above and the sound drops out. I have bad hearing as it is but I know the driver dies when my sound drops down to hard to hear levels. when I switch from the different modes, Movie, Music and so forth, you can tell when it is working the changes in the sound quality based upon each modes settings.
I'm still stuck with uninstalling the whole driver package, then reinstall the driver and it works for a certain period of time. Generally in the time frame of hours. the driver seems to malfunction, not the blue screen kind of malfunction but the driver stops working. I still get sound but VERY degraded quality and hard to hear. Which is why I am forced to uninstall and then reinstall. this is a serious issue in my book because it has been doing this for at least the last 4 preview release ring builds. probably more easily at least since 14393.xxx .
whatever the driver uses for sound quality just quits functioning. Can you folks at Nahimic create a utility that we can run in the background or start it when I notice this loss of functioning to interrogate my laptop to create an error report send back to you guys so you can figure out this issue?
