        I have an HP Spectre x360 15t-ch0xx.  These systems originally come with a Realtek audio driver.  As with apparently many Realtek drivers, it had problems; the main was that it would start playing audio about 2-3 seconds after you you started the video/whatever.  Annoying.

        Following advice online, I ditched the Realtek driver and went with a generic Microsoft driver.  That solved the 2-3 sec delay, but I believe this was the one with the mushy/crackly distortion in the left channel through the headphone jack — which I use 99% of the time to feed larger/better speakers.

        In May HP posted a new Realtek driver (Release 6.0.8940.1 Rev.B, 5/5/2020). It works… most of the time, sorta.  My current headache is that the audio gets out of sync.  Usually the audio leads the video, by as much as 0.5 – 1.0 second or more.  This is VERY distracting when I’m using the laptop to drive a projector to watch a movie — or Hamilton, as I did this week.

        Sometimes I can restart the player and that will resync the sound… but then it quickly drifts off again.  And this is not an ideal solution when you’re trying to watch a movie.  The delay happens regardless of video source:  Youtube, Disney+, whatever.

        As far as I’ve noticed, it does NOT do this with a USB speaker.

        Any suggestions?  How can I make this thing work the way it’s supposed to??

        Have you tried turning OFF “Allow hardware acceleration of audio with this device” in the advanced properties for your sound device/card?

        Control Panel > Sound > (select sound output device) > Properties > Advanced


        In the same place, turn off all “enhancements” and test.

        I had not done that.  I’ve turned it off now.  So far so good — I will report back if it does/doesn’t seem to fix the problem.  Thanks @NetDef!

        Well, bother.  I watched a movie and it seemed OK.  I thought I maybe saw a little lag but by the end of the movie it was fine.

        Then I watched another, and almost immediately the sound was out of sync.

        Did I need to reboot after turning off that hardware-acceleration setting, or anything like that?

        No other suggestions?  No ideas to fix this very annoying lag?  @NetDef?  Anyone?
