    One thought...

    You could do a clean install.

    Realtek works OK on my install (10074).

    Try a "recycle". Go to the Device Manager, uninstall they sound device, but DO NOT uninstall the drivers. Then restart Win and when Win 10 starts it will detect and reinstall the sound. Fixes a lot of flakey problems.

    If you are talking upgrade of the build,then try manual updating your pc and restarting. If you are saying the update that MS pushed out for patch Tuesday try that again, If not that try updateing your driver by going to device manager.

    You can try this before a clean install. Sometimes you have to force-feed the drivers if they get quirky, especially with test software like Win 10.

    Go into Device Manager. Right click the Sound, Video and Game controllers. You will see the two devices associated with it.
    Right click each one and try to update driver with search automatically. It will probably say they are up to date.

    If they get updated, fine. Reboot and check your sound.

    If not, which is most likely to happen, right click each and UNINSTALL the device. BOTH. Drivers, too!

    The reason for uninstalling the device AND the drivers is to make Windows download a fresh copy of the driver software and not use what is stored in the Driver Store on your computer, which may be corrupt.

    Reboot and Windows will re-install the devices and hopefully get the drivers installed correctly.

    Same applies to video driver. May be causing your slow videos. Video device and driver is under Monitors.

    This process of rebooting and Windows detecting device, finding drivers, and installing is what would happen if you were to add a brand new device and power up the machine. To use old-school terminology, the system "sizes" the devices, loads what drivers it has for found devices, downloads or searches Driver Store for new devices, and installs new and loads new drivers.

    This is all much quicker and less painful than a clean install, but not guaranteed. Good luck. :)

    Well, everything's working again. It was working before. It must have been the update patch. Thanks for all the suggestions. I did uninstall the Realtek before and restart but didn't cure anything at that time. Now, out of the blue it's good. I installed 9926 on a new SSD earlier and have upgraded on the fast ring ever since. I will clean install at RTM or I may just stay with Win 7 Pro.

    Good, glad it is working for you now. I think 10074 is a good build. :)

    Just an FYI to others that find the same issue. Today (yea much later) I did the win 10 upgrade on my desktop, sound wouldn't work after it. I played around with some different suggestions about making sure it was set to HD (i have Logitech X-540 5.1 surround sound speakers), Realtek HD audio. So in the end i downloaded a driver from the Realtek site, went to the device manager and clicked update driver from on my pc, browsed to where i put the driver and the message came up saying you already have the most up to date driver. Closed it, didn't reboot and my sound was working... all 5 speakers. So not sure what is buggy but I suspect if i had just hit the update driver without even downloading and browsing it would have fixed it. I wasted an hour, try that first.
