No sound after update

B

Hi,

Windows 10 updated to the latest version, this one Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting , there was a gpu update as well, this one Image - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting , but after this the lappy has been left with no sound. No sound in YT videos. I use mpc for video files, if I open any movie mpc like hangs for 2-4 or maybe more minutes and then plays video without the sound. I have to close it if it takes more than that time. Ran the audio troubleshooter but it kept on loading and loading so I closed it. What should I do?

Thanks

Already latest drivers as per Device Manager.

Don't check using device manager,most of the time it is useless.

Rollback driver if possible(option in device manager,same place as update driver),you can also try reset/refresh.

Just started the pc, and the sound output was gone for few minutes and then it came back

The same thing happened yesterday also. If I click on troubleshoot it keeps on loading and loading. Driver rollback option cannot be selected unfortunately. I think problem is more than the drivers as the videos take a ton of time to start and they they either lag or hang in mpc. Moreover many apps are hanging or either they stop responding after a bit including browsers FF, Edge etc.
I cannot format anything. Please advice.

Rollback to previous windows update.

How? Will it delete anything especially from c drive?

B

Winamp opens fine but as soon as I click on play it stops responding.

B

If I uninstall the two updates installed yesterday, then will it delete anything?

^^he doesn't need to delete win 10 april update,issue seems to be with KB4284848 which updates win 10 build to 17134.137 & as per some reports it is such a major update that it basically rewrites system32 folder.

@billubakra uninstall KB4284848 & see if it solves the issue.Be sure to disconnect net access during/after uninstalling this update to test if it solves the issue.

Brother actually the April update is fine. It is only the update that was installed 2 days ago that caused this. Check post #12 should I uninstall those? Will it affect any files?

Just uninstall KB4284848,it should not affect any personal files.

Solved. Thanks. How do I stop that update from auto downloading? If I use some update stopper/blocker then how would I know that a patch or something is there?

You are using win 10 pro correct?Have you tried the driver update block link I posted earlier?

Home, preinstalled in laptop. No, because it is not a driver update but a Windows update as a whole which it is again auto downloading.
Anyone else got the same update from Windows?

W

This is a build upgrade so everyone will eventually get it,from what I have seen online this is a major update & causing issues for some people.Driver updates are included in cumulative updates so using that way it should be possible to install an update skipping driver update parts.However it needs group policy which home version doesn't have.

B

Ah, any other way out? I need to check which version my home system is running.

W

version of what?driver version can be seen in device manager,windows version can be seen in system properties.

Windows update and driver version in my home pc having 10 home installed.
Anyways same update has been again auto installed. Sound seems to be working as of now. Will report back after some time. Where did you read that this specific update is causing issues?

W

Somebody posted about large increase in backup images after this update indicating large changes caused by this update & someone posted about some crackling sound issue so I thought this update seems to be best guess for reason behind your issue.
