@shreynagpaldpsg, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
sounds like you're dealing with a couple of hardware/driver issues on your HP Victus laptop running Windows 11. Let’s walk through each problem one at a time.

🎤 Mic Not Working (Not Detecting Input)

Step 1: Check if mic is enabled

• Press Windows + I to open Settings.
• Go to System > Sound.
• Under Input, see if any microphone is listed, 
  If it's grayed out or says "No input devices found", continue to the driver fix below.
• Try tapping or speaking into the mic—check if the volume meter reacts.

Step 2: Privacy permissions

1. Go to Settings > Privacy & security > Microphone.
2. Make sure Microphone access is turned On.
3. Also, make sure apps you want to use (like Zoom, Teams, etc.) have permission.

Step 3: Update/reinstall mic drivers

1. Press Windows + X → Choose Device Manager.
2. Expand Audio inputs and outputs.
3. Right-click on the microphone device (could say “Microphone Array” or similar) → Click Uninstall device.
4. After uninstalling, Restart your PC—Windows should auto-reinstall the driver.

💡 Brightness Not Changing

Step 1: Check brightness keys

Try adjusting brightness using Fn + F3/F4 (depending on your keyboard layout). If no response, it could be a driver issue.

Step 2: Check Windows settings

• Go to Settings > System > Display.
• Try moving the Brightness slider — does it change anything?

If not…

Step 3: Reinstall Display/Graphics driver

1. Press Windows + X → Choose Device Manager.
2. Expand Display adapters.
3. Right-click on the graphics adapter (e.g., AMD Radeon / NVIDIA / Intel) → Click Uninstall device.
4. Check “Delete the driver software for this device” (if available) → Uninstall.
5. Restart your PC.
   After restart, Windows will reinstall a default driver. You can later install the latest official GPU drivers from:

• HP Drivers for your Victus 15 (598U8AV)
• Or from AMD/NVIDIA/Intel directly depending on your GPU.

🔄 Optional: HP Support Assistant

If you haven’t already, install HP Support Assistant – it can automatically detect issues and install missing or outdated drivers.

I hope this helps. 

Take care and have a good day.
