I apologize for the inconvenience caused to you.
I understand that you are facing issues with Windows 10. Switch to the "Playback" tab and increase System sounds volume to 100%.Thank you for posting your query on Microsoft Community. You may also need to change the ALSA plug setting from "Built-in Audio Analog Stereo" to an alternative audio device that is listed there. You can tell by whether the little mute icon appears depressed or not. In this application - PulseAudio Volume Control - look through the tabs and see if either the input or output device is muted. Then run the pavucontrol program from a terminal or by pressing Alt-F2 and typing Sometimes the playback device is muted by default.

Wait 10 seconds, then reboot (putting the machine to sleep is not enough - fully power it off and then back on).
Killall pulseaudio pulseaudio -k rm -r ~/.config/pulse/* rm -r ~/.pulse* If you are using Ubuntu 14.04 LTS or later: Should the approach above fail to correct the problem (it is only known to work on some variations), you can try this next. If you are using Ubuntu 14.04 LTS or newer, try this first: While the outcome of running the suggested command string below may indeed fix certain sound problems, be aware that it is a very blunt approach and could result in unintended consequences. This will likely create problems for users of the other flavors of Ubuntu - a Kubuntu user would not want the Unity interface installed. For instance, the sudo apt-get install command includes the entire Ubuntu desktop. Please exercise caution when running these commands! Carefully read and understand what they do. The only supported releases of Ubuntu are the ones that are NOT End of Life (EOL) in the following table: OpenSource systems are about freedom OF choice so it's good that people are able to choose which pages they use. The various different pages about sound issues each serve a different purpose or different tastes. This information will be useful in posting a question to launchpad and getting help from volunteers who are monitoring the Launchpad forums: You may want to follow this guide to gather essential troubleshooting information about your sound card.
