Realtek line-in

[dhamilton70]

My Realtek line-in goes to zero after a few seconds. This started happening back in January. I have uninstalled and reinstalled Realtek drivers about 20 times. Right now the driver is 6.0.1.7071. The original driver was 6.0.1.6196.

I thought there might be a virus, but have Microsoft Secutity Essentials, not that it's perfect. Do you have any answers?

There are no error messages. I have a wireless internet.

Thanks,

Doug Hamilton

Thank you for joining HP Forums.}

I'll be glad to help you 🙂

As I understand the Realtek line-in reduces the volume on it own within a few seconds,

Don't worry as I'll be glad to help you, although, to provide an accurate solution, I'll need a few more details to dissect your concern: 

Is it a few seconds after the computer is turned on? or after a certain application is used?

Did you perform a system restore to an earlier time it had been working fine?

What are you using the Line-in port for?

While you respond to my questions, here's a few things you could attempt:

By default, Windows 7 automatically enables microphones and line-in ports. Use the following steps to set the microphone/line-in port to be the default port and to configure the recording levels:

1. If the Recording tab in the sound window is not selected, open the Sound window and click the Recording tab using the instructions in Step 1.

    NOTE:

   Your desktop or notebook PC configuration may include different components then shown here.

   Figure : Example desktop PC with a Realtek on-board audio hardware configuration)

   1. Microphone port -  working and set as Default

   2. Line In - Working

   3. Digital In (S/PDIF port) - Working

   4. Stereo Mix (Software mixer) -  Disabled

2. If multiple microphones or line-in ports are available, select the port that you want to use. Click Set Default to make this device the default audio input device.

3. If the device you want to use contains a small circle with an arrow pointing down, the device is disabled. To enable the device, right-click the device name and select Enable.

4. With the device selected, click Properties, and then click the Levels tab.

   Figure : Microphone Properties: Levels tab

   

5. Adjust the slider to 75.

6. If Mute is on, click the mute button to un-mate the device. The mute button should show as a blue speaker without a red circle.

7. If Microphone Boost is available, adjust to +20.0 dB.

8. Click OK to make the changes.

9. Test the microphone using the instructions in Step 1 to determine if Windows is able to detect a signal for the microphone or line-in being used. If you have performed all the steps and the microphone or source device still does not work, the audio ports or sound hardware on the computer might be bad.

I thought the realtek line-in volume going to zero was fixed. It worked as it should over the weekend. Today it's going back to zero again. I'm using line-in to record vinyl and it happens when nothing else is running. I have done everything in your how-to's. If I just get into the realtek HD audio manager and move the volume slider to any positive number, it goes back to zero in few seconds. I hope you can provide a permanent solution.

Thank you

Thank you for the update,

I appreciate your time and efforts,

If it worked over the weekend, we'll need to identify what changed during this period?

perhaps, a system restore to last working week, disable automatic windows updates and then do a manual update one at a time to find the cause of the failure,

It's entirely possible an update done during this time could have caused this issue,

I'll be eagerly awaiting your response to ensure a complete/permanent solution is provided this time.

Realtek line in volume goes to zero.

I restored four times yesterday and turned off automatic updates including all other updates. I had the same result  and the same thing today. Is it possible to get into the registry or the command prompt to find a problem, or any other ideas would be appreciated.

Thank you for your help.

I just discovered that the line-in volume goes to zero when I plug 3.5mm plug into the microphone-in jack.

I hope this helps.

Thanks,
