Perform a non-"fast" reboot after installation
Your installation of Windows 10 may be configured (typically as part of the default settings during Windows 10 installation) to perform a hibernation-like shutdown, to enable a quicker method of booting called "fast startup".

Using "fast startup" apparently contributes to a known problem with the Steam version of Supreme Commander: some of the game audio will not play, such as cut scene audio, character voiceovers, or some combat sound effects. Rebooting through the usual "fast startup" method does not resolve the problem. What fixed this for me was to disable the Windows 10 "fast startup" feature.

To disable Windows 10 Fast Startup, navigate to Windows 10 Settings, then navigate to System > Power & Sleep > Additional System Settings > "Choose what the power buttons do".

In the resulting Control Panel\Hardware and Sound\Power Options\System Settings dialog box, click "Change settings that are currently unavailable". This should enable the previously greyed-out checkbox "Turn on fast startup (recommended)". Uncheck this.

Click Save Changes, then reboot your PC. With luck, this should resolve this Supreme Commander audio problem.

After some testing, it appears that re-enabling "fast startup" later will not cause the sound bug to re-occur.

Changing the audio in windows to "16 bit,44100 Hz" worked for me! Thanks the comment provided by ♠Jade♠.

Rebooting did work for me.
I also played in compatibility mode for win XP/SP3.

For those having this issue, the only thing you need to do is change a particular sound setting.
Go to sounds>Playback>output device>properties>advanced.
Where it says Default Format click the dropdown menu and select "16 bit,44100 Hz (CD Quality)".
That is the sample rate the game was designed to output, using anything else will cause sound issues. Enjoy the beautiful sounds of conquering :)

In my case, I found a full shutdown (power off) and restart fixed the problem, even with "fast startup" turned on. After that, the movies audio played and all the game audio seemed fine, no problems so far.

In my searching for a solution, people on other sites also suggested rebooting to BIOS and disabling the built-in sound card, rebooting back to Windows, then rebooting and re-enabling the sound card. Apparently it worked for some people that a simple reboot didn't work for.

Опять столкнулся с этой же проблемой - решение помогло (переустановка на другой диск) - Почему-то игра не любит SSD - нужен ей обычный диск...

Была проблема - пропадал звук в видео, а так же музыка и голоса. Решение проблемы оказалось "странным" смена диска установки (стоял в А:\steamlibrary\..., переустановил на Е:\steamlibrary\...)
