Windows 10: Realtek HD speakers make no sound

I have an ASUS desktop PC with Windows 10. My Realtek speakers have been working very well. One day they did not work. I'm not aware of any changes I may have made in settings. I have not been able to get them to come back on line. I downloaded the latest driver and it still does not work. I tried troubleshooting. Comes back with the devise is working? I know the speakers themselves are working but not with my PC. The Windows software recognizes the Realtek speakers so there is no hardware problem. What can I do now?

Realtek HD audio speakers "Not plugged in"

If your case has two front panel audio connection options, did you use the
HD audio motherboard connector ?

AC97 is 'legacy' and may not work on some current motherboards.

( There may also be an option to switch between HD and AC97 in the Realtek audio manager, or BIOS

when using an HD audio connector. If your Realtek audio manager has this option, play around with

this for different results with the other settings that control front and back panels )

- Do either speaker or headphone show in Device Manager, Control Panel > Sound,

and the Realtek audio manager ?

'I have like 2 headphones plugged in and two front speakers '

- Start out with either speakers, or a headphone until you get the audio going.

Use the rear outputs for the speakers, and front for headphones.

I would be inclined to try and get the rear speaker output going first because it is connected

directly to the motherboard.

Realtek HD Audio latency leading to crackling sounds from the speakers

I have a problem with the Realtek HD Audio speakers driver. Everytime a sound is about to be play, the speakers of the laptop make a crackling sound, similar to the sound of static electricity.

I am using Windows 10 and have the latest version of the Realtek HD Audio driver.

I ran the Latencymon v 6.50 to check for latencies, and I get the following result:

"Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one problem appears to be network related. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates."

These results appear to be spot-on, however I'm surprised it mentions that at least one problem is network related, since I have the latest network drivers, and even when disabling the network adapters I still get the crackling sound.

I reckon the CPU throttling mentioned is related to the CPU exectution cap which I already set to 100%.

The other thing I need to mention is that this is a new laptop, and from the first day, even with the old drivers I noticed the crackling sound, and I assumed it would go away after I updated the drivers. I have all the newest drivers and I still get this problem.

The funny thing is that when I plug-in the laptop, it somehow does not give the crackling sound, but when I approach my ear to the speakers, I hear that they are on, even when nothing is playing ( I know because they emit some kind of barely distinguishable white noise). When the laptop is not plugged in however the speakers make the crackling noise before playing sound, and when they finish playing the sounds, the speakers go off ( when I approach my ear the white noise isn't heard anymore).

Notice that the crackling sound is heard only once: after I click on some audio to play; then the crackling disappears, only to appear when I got to the next song ( or audio file).

What do you suggest I do about it? In the beginning I thought it was a hardware problem, but given the fact that during playback the speakers do not exhibit any weird behavior, I am led to believe it is a drivers' problem.

 

Sound Quality

One thing that sticks out from looking at your "My Computer" specs. You list "ONBOARD 6 CHANNEL (5.1) HIGH DEF AUDIO (AS STANDARD)" which suggests you do not have the correct sound hardware driver. Your motherboard has Realtek sound and the first step is to install the Realtek sound drivers. My ASUS also came with Sonic Studio 2 which is a sound enhancement package. Check the ASUS install disc to see if you have something similar.

May not be a speaker problem.
