Volume on audio output reduced

Hi John C,

I can see that the Q&A Assist has already provided a number of helpful steps for restoring your audio output following the recent update so I would recommend giving those a try if you haven’t already done so.

In particular, since the issue appeared after a Windows Update and your volume had previously improved with a different driver installed, I’d suggest focusing again on the following: Reinstall or change the audio driver (including installing the OEM driver from your device manufacturer’s support website). The current driver may have been replaced with a more generic version during the update, which may reduce overall output even if it reports as the “latest.” Reinstalling or switching to the manufacturer‑provided (OEM) audio driver for your exact model may restore the previous sound calibration or enhancements that helped improve your volume before.

If the lower volume began immediately after the recent update, you may also try rolling back the audio driver via Device Manager. This restores the previously installed driver version that Windows may have replaced during the update process and can often return audio performance to how it was before:

1. Right‑click the Start button and select Device Manager
2. Expand Sound, video and game controllers
3. Right‑click your audio device (for example, Realtek Audio) and select Properties
4. Go to the Driver tab
5. Select Roll Back Driver and follow the prompts
6. Restart your PC when prompted

You’ll need administrator permissions to perform this step, and if the option is unavailable (greyed out), it means Windows does not currently have a previous driver version stored to restore.

If the issue occurred after a Windows Update, reinstalling or rolling back the previous driver should help resolve sound‑related problems.

Please let me know how it goes after trying the above. I’ll be glad to assist further if needed.

A recent Windows Update likely replaced or changed the audio driver or its settings, which can reduce overall output volume even if the driver now reports as “latest.” Use these steps to restore louder output:

1. Check per‑app and system volume
   1. Select Start > Settings > System > Sound.
   2. Select Volume mixer.
   3. Make sure the sliders for System and the apps used for music/video are turned up and not muted.
2. Turn off audio enhancements Audio enhancements can lower or alter volume after a driver or Windows update.
   1. Go to Start > Settings > System > Sound.
   2. Under Output, select the audio device in use.
   3. Select Audio enhancements.
   4. Turn enhancements Off and test sound.
3. Try a different audio format
   1. In Settings > System > Sound, under Output, select the device.
   2. Select Advanced.
   3. Under Default format, choose a different format and test audio.
4. Reinstall or change the audio driver Because the problem returned after an update, the current driver may not be ideal for the device.
   1. Press the Windows key, type device manager, and open it.
   2. Expand Sound, video and game controllers.
   3. Right‑click the audio device (speakers/headphones) and select Uninstall device.
   4. Check Attempt to remove the driver for this device if available, then select Uninstall.
   5. Restart the PC so Windows reinstalls a driver automatically.
   6. If volume is still low, repeat step 1–3, then choose Update driver > Browse my computer for drivers > Let me pick from a list of available drivers on my computer and test the generic driver.
5. Install the OEM driver again If the OEM driver previously gave better volume:
   1. Go to the PC or motherboard manufacturer’s support website.
   2. Download the latest Windows 11 audio driver for the exact model.
   3. Install it and restart.
6. Roll back the driver if the issue started after an update
   1. Open Device Manager.
   2. Expand Sound, video and game controllers.
   3. Right‑click the sound card/audio device > Properties.
   4. On the Driver tab, select Roll Back Driver and follow the prompts.

If the problem persists after these steps, use the full audio troubleshooter sequence in Fix sound or audio problems in Windows to continue diagnosis.
