Windows 7: windows 7 realtek sound disappears after restarting pc

windows 7 realtek sound disappears after restarting pc

I installed Windows 7 (x86 so x32 for instalations) recently and from beggining I had problems with sound. After installing windows all other drivers were ok(video,motherboard,ethernet) but there were no sound. Windows showed that there is sound drivers instaled S/pdif(or something like that) and as I turned music on bars moved, but there was no sound from speakers. I havent muted anything by myself and wtf I just installed win it shouldnt be mutted anyway.

So I installed realtek newest audio High definition drivers which is my integrated sound card compatable with, restarted PC and vualia it worked. New icon appeared, I heard sound from music/movies. But then I shutted down my pc, turned it in couple of hours and they werent there anymore> Windows showed that there are no outputs or smth, red cross were on sound sign, then installed default drivers who were at the begging then I installed it. And bam I can't hear sound again. I read that problem might be when windows sended updates it sends realtek lan instead of sound or smth like that. And I found it in update history that win send realtek lan, but I dont know if disabling it could solve the problem. Do you guys have any Idea?

S/PDIF -> Sony/Panasonic Digital Interface is to connect to an external receiver via optical cable.

Make sure you have your speakers plugged in properly and select Speakers as your default output, unless you actually have the PC connected to an external receiver via optical cable.

My speakers are connceted, if it won't be, how could I hear sound then realtek is installed. The main thing is that after shutdown realtek dissapears, and I dont' know what causes it. I read on different forums that I need to change my speakers to a different jack.

Can you identify the computer hardware? Make/model? Compaq, HP, Dell? Model and/or serial number?

My pc ain't laptop, in stacionary. And sorry I can't give you my pc specifications(motherboard) because I'm not at that pc right now. Ill write it ASAP. But I believe main problems is that win 7 have bug there with jack detection.I found this one on internet and Ill try it later, but until then maby know what works for real? Maby someone had same problem already on this forum?

I had trouble getting the Realtek sound on my Intel DG33BU motherboard to work. My speaker in the tray had a red “X” through it, but the drivers didn’t seem to have any problems. When I tried to automatically upgrade the sound driver, it told me that I had the most up-to-date driver available. I kept getting a message saying that the speakers were not plugged in. Lo and behold, as I have found in almost every case, the few problems I had in Vista have not been corrected with Windows 7. Hopefully the Googlebot will pick this up and help others with Intel Realtek sound problems in Windows 7. I was able to get the sound working in Windows 7 by disabling the front panel jack detection. The way you do it isn’t intuitive. First download and install the latest audio drivers from Intel’s website (here is the link for the DG33BU). Then:

  • Open Windows 7’s Control Panel (Start| Control Panel)
  • Open the "Realtek Audio Manager" (not to be confused with “Sound”). (In order to display this, be sure that "View By" in the upper right shows "Large Icons" instead of "Category"
  • 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.

Or do I need to install my motherboard drivers manually? But ain't win 7 do that automaticaly? and if thats where the problem is, how then sound worked after realtek install?
