As my computer have not sound when I check it the message display "There is no Active Mixer Devices Available." You may install mixer devices from the Add/Remove Hardware Wizard in the control panel.

Please advise.

Building on and , the "There is no Active Mixer Devices Available" message simply means Windows has no audio endpoint registered for the mixer to control. Beyond checking for missing drivers, a few less-obvious checks often resolve this.

Check Windows audio services with services.msc and confirm Windows Audio and its dependency service(s) are set to Automatic and are running. Firmware can hide hardware: verify onboard audio is enabled in the BIOS/UEFI (look for "Onboard Audio", "HD Audio" or similar). Install the motherboard chipset drivers before any audio driver—audio controllers often rely on chipset components being installed first (AC97 vs. HD Audio matters).

If the device shows as unknown, use the device Properties -> Details -> Hardware Ids and note the VEN and DEV strings. Those identifiers make it possible to find the exact vendor driver when a generic name is not listed. Physical checks matter too: confirm speaker power, correct jack, front-panel audio header connected on desktops, and laptop mute/function-key state. A quick hardware isolation step is to test audio with a USB headset or boot a Linux live USB; that separates hardware failure from driver/OS issues.

When changing drivers, create a restore point or backup the current driver first. If all else fails, capture the PC model (or motherboard model), exact Windows version, and the Hardware Ids string—those details make targeted driver lookup practical and avoid trial-and-error installs. This complements the earlier advice about device listings and driver installation and narrows down the likely causes.

Go to your Device Manager by right clicking on My Computer and selecting Properties from the bottom of the list, then pressing the Hardware tab.

Look down the list for any Yellow exclamation marks showing hardware that is not installed.
If there are, you need to install the drivers for your audio card by finding out first of all whether it is on-board or a PCI card, and then, what manufacturer it is.

If there are no yellow marks by your devices then I would suggest removing the drivers for your audio card through Add/Remove Programs from the Control Panel, and also before restarting, use the Right Click > Uninstall feature on your Audio Device in Device Manager.
Let the computer restart and re-detect the audio card and see whether it picks up the audio device and tries to install it. If it does let windows find the driver automatically and install itself.

Unfortunately if that doesnt work the drivers that windows has chosen arent doing their job correctly and you are going to have to start searching the net for drivers for your specific card.
