Hello, I suggest to run windows update and make sure the pc is up to date, if with the updates still the behavior, install the driver from the link below. and let me know if this works.
What is happening all drivers will be available from now on through windows update.
Hi Ricardo & thanks for answer;
I tried installing the driver you linked but no success.
Note that issue started to occur after an update & that sound through laptop is ok even after sound through hdmi crash and that i have to reboot to get back hdmi sound.
could it be an nvidia issue or is it the "sound intel(r) for external screen" (i think the previous driver had hdmi in its label how could i revert to find out ?)
thx in advance for assistance
I had the exact same thing. I updated the HD 4600 windows 10 64bit driver which shows up as driver 10.18.15.4256
BUT it also updates the Display Audio driver to 126.96.36.19979
This Display Audio driver is bad
I had to find an older windows 8 HD 4600 driver and downgrade the Display Audio driver to 188.8.131.5254 from 9/9/14. Anything newer and the audio doesn't work properly
I can confirm that darrink1 is correct; thanks a lot to him.
After uninstalling latest Display Audio driver & reinstalling the old one he recommended (downloaded from softpedia) through device manager sound in games through hdmi is now back.
Ricardo may I ask if there is an online bug tracker or how shall we know when this bug is fixed in a next release ? thx
My issue is very similar. I have an Asus N550jv (i7 HQ4700, Nvidia 750m, Intel HD 4600, 8gb ram) that was just updated from Windows 8.1 to 10.
The sound only cuts out when I start to play a game (say Minecraft, for example), which is nothing obscure and worked fine with Windows 8.1. As soon as I start it the sound cuts out and the volume bar no longer gives me a noise (until I restart the laptop).
I tried to uninstall the 3179 driver and replaced it with the 3154 driver, but the problem remains. I have also tried other, older drivers as well to no avail.
yes completely remove the intel driver for hdmi audio & let windows install its own driver for hdmi audio at the next restart.
(i'm not linux right now & don't remember the name of that ms driver)
still not perfect though soemtimes no hdmi sound at all. work around : i reset the audio output to the laptop before switching off to be sure hdmi audio will work on next start (after resetting to hdmi the audio output obviously).
Hey, thanks for the reply!
@mikakun: I did try that a few times and had the same luck. Sometimes no sound, sometimes it worked until starting a videogame.
@ricardog_intel: That was my first time trying that driver. It did not show up when I tried to update from Device Manager or with Intel Driver Update Utility. Unfortunately, like the other drivers, the sound worked initially when I restarted the PC but ceased to work again after starting a game.
It's kind of frustrating because everything worked great when on Windows 8.1 before moving to 10. I do not know what drivers I had at that time that worked, but even with trying older Windows 8.1 drivers I still have the problem. Asus only has the Intel Graphics driver for Windows 8.1 and not 10 on their Asus N550jv page, but even when trying that Intel Display Audio driver I get this problem. Could I be missing something?
I am also experience this problem when playing titanfall if the game is minimized when started sound will play from the TV attempting to change the audio settings causes the game to freeze
also the game uses the laptop monitor resolution instead of the TV resolution (the TV is set as the primary display so the driver is causing the wrong resolution to be reported to the game)
