I accidentally hit the "Set Default Device" button in my laptops Realtek HD Audio Manager and cannot get any sound now. Please help?

Open Device manager and right click on "Realtek HD Audio"
Select 'enable'
Right click on the speaker icon in the taskbar and select 'Playback devices' ensure that Realtek is checked as the default speaker device
Right click alongside the speaker icon and make sure they are not disabled
Use the 'Test' facility to check the audio
You may have to update the driver as well

realtek hd manager is bundled with audio driver, if you uninstall it , this mean you uninstall audio driver too, just install again audio driver and you got your sound again
i hope this helpfull, if you think this helpfull please rate very helpfull or helpfull
thanks for using fixya

if it cant start then realtech is not the proper sound card install the correct driver

Hello

OK, all you need to do is to open the Manager from the start tray, once the manager is opened, Click on the speaker tab, and then on the Sound effect tab. You should see something like this now.


Now just click on the reset tabs, this should then reset the manager to it's default settings.

Please let me know if this was helpful. Also,, let me know if you need any further assistance.

Kind regards
Andrea

Open your control panel.
Click on Sounds and Audio Devices with the control panel in classic mode.
Click on the Audio tab.
Is Realtek HD Audio Input Device listed as the default device under Sound recording?
If not, select that from the drop down list and click Apply/OK.

I had this problem for months - I finally figured it out on my own...

Go to your RealTek HD Audio Manager (this is either a red speaker icon in the bottom right hand corner or if you go to 'control panel, sounds speak and audio devices, realtek hd sound effect manager)

once you have the window open, under 'sound effect, go to environment and to the right of the drop down menu, click 'RESET'.

After months of trying to fix this issue, this fixed it for me!!! I hope it does for you too!

I found many references to this issue but I am not sure which may apply to your problem. Here is a set of steps to follow from another site: (Assumes Vista and Realtek)

• Open Vista’s Control Panel (Window | Control Panel)
• Open the Realtek Audio Manager (not “Sound”)
• In the navigation bar in the far right, there is a little yellow folder icon. It is just below “Device advanced settings” and above “ANALOG”. Click the folder icon.
• Click “Disable front panel jack detection” so that a yellow check mark shows up. Hit “OK”, and close the Realtek HD Audio Manager. That should re-enable the sound.

Sounds like you are running Vista. If so, do you know if you are useing the RealTek Audio?

ATI is the graphics card developer. Your motherboard has onboard audio that appears to be Realtek. You should not have an ATI sound driver... as they don't exist.

I'm assuming you're using WinXP to make thing simple. If you're using Vista, try to do the equivalent.

Since your graphics card is capable of HDMI, the problem could be that the card expects to output audio through your graphics card rather than the sound card. Check start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings -- go to the Audio tab and make sure it says Realtek for output. If it shows more than one output device, set it to realtek. If it doesn't show realtek, follow the below instructions, and then double check at the end that the Output device is set to Realtek.

1>Please go to HP's site and download their Audio drivers.
2>Go to Device manager -> Sound, Video, and game controllers.
2.1> Does it have an entry saying "Realtek blah blah Audio" there? If not, what entries does it have for audio? Ignore Audio Codecs and Legacy Audio Drivers.
2.2>If there's nothing there, you need to install the drivers you downloaded. If there is something there, please continue to #3.
2.3>After installing the driver, restart computer.
2.4>Once computer is restarted, go start -> Control Panel -> Sounds and audio. -> Sounds and Audio Devices /or/ Adjust Speaker Settings. Hit the button labeled Advanced and adjust the speaker setup to whatever you have - surround sound, 5.1, quad, stereo, whatever.
2.5> Go to #5
3> If there is anything that says Realtek/Azalia Audi, right click it and Uninstall.
3.1> Restart computer.
4>Install audio driver you downloaded, and perform #2.4.
5>Find the driver icon (there's probably on in the task tray) or find it under start -> Control Panel -> Sounds and audio. Set your speaker settings there as well. Audio I/O should specify what ports go to what speakers What you set in windows should match the Realtek audio manager's speaker setup.

If problem persists, please report this.
