Re: DELL XPS 9575 Sound and touchpad issue

For me, reverting to BIOS 1.1.7 seemed to fix the track pad freezing issue:

For the sound dropping out I open the device manager and disable and then re-enable the Realtek sound driver.  Not great, but this will allow you to get the sound back without having to restart the computer.  I have asked for Dell to look into this in every way I know.  Still no driver update...
