How to fix Static Sound in Windows 7 64 bit

By jdlunt191 ·
Specs:
Acer Aspire M3100 (purchased Feb 2007)
AMD Athlon x2 64-bit @ 2.4GHz (never overclocked)
530W PSU (Upgraded from original 250W)
4GB DDR2 RAM (2x2GB) (Upgraded from 3GB (2x1GB 2x512MB))
Windows 7 Home Premium SP1 64-bit (installed Dec 20, 2013)
ATI Radeon X1250 (Integrated)
Realtek HD Audio Card (Integrated) (cause of problem)

The problem is that whenever I attempt to play any kind of audio (ranging from music/videos to Windows Sounds), all I hear is static. I've gone from the standard Windows driver to an outdated Realtek driver to the most updated Realtek driver with no improvement. I've installed Windows 7 via original DVD and USB via official Microsoft download (in other words, all copies I've used are genuine). I've also tested both audio jacks (front and back). The HDMI (part of the aforementioned Radeon X1250) will not send any audio at all.

I've run all Windows Troubleshooters, including related Microsoft Fix-It applications; but they stated nothing was wrong. I had tested the RAM and HDD, which both came up healthy. I also checked hardware compatibility (RAM, PSU, and so on) and found no issues there.

I've followed other forums and disabled all of the other audio outputs (namely SPDIF/Digital Out and HDMI) with no improvement.

However, I had no problems with the audio when running Ubuntu13.10 via Live USB.

If you need other details, you need only ask.

In short: I need help. I'm putting this computer together for a friend of mine, and I've had to delay handing it over for this reason.

Concerning the downloaded Windows ISO

by jdlunt191 In reply to How to fix Static Sound i ...

I forgot to say that the downloaded Windows ISO was placed on a USB drive and installed that way.

Concerning other drivers:

I've run updates for all of the other drivers, and Windows is fully updated.

Also, Acer never released a BIOS update for this motherboard, and I could not find one online.

I did reset the BIOS to defaults as well.

Again, if you need more details, please ask! I'll answer them as best as I can.

Hardware or software

by mjd420nova In reply to How to fix Static Sound i ...

To find the fault with static and dropouts in an audio stream, try running the application in safe mode, that will have the least number of junk loaded ahead of it and if the static remains, then it is hardware at fault. Isolating any analog audio leads or sheilding them and keeping them away from other cables/lines. Software can be tough to isolate but is usually based within a program running in the background or an interupt conflict. My Realtek onboard audio allows me to select sending it through the HDMI port (on board) and not the line out or headphone jack. Ubuntu obviously got it right so it might be something in the background, grabbing a couple extra machine cycles. When I build units for myself or friends, the hardest part is getting all the hardware and software to play nice together. Loading sequences and setups options can help. The WIN task manager is a big help, first establishing a starting or bare install of the OS and taking note of what prosesses are running and what gets added during each subsequent install of drivers, programs and options.

I've checked the background processes and didn't find anything out of the ordinary. I had also looked at the Task Manager and Performance Logs and found nothing unusual there. On one of the times I reinstalled Windows, the very first driver/software I put on was strictly for the audio; and it still gave me nothing but static. However, I had tossed a WiFi card into the machine; inserted into the slot furthest from the PCIe Video Card slot (my friend has a video card he wants me to install as well, so I'm having them as far apart as possible for heat transfer prevention. Not sure if this means anything, but I thought I'd comment on that; because this puts the WiFi card next to the jacks for the front audio, USB, lights, and power button). I've not tried taking that out yet, so I'll do that.

Just to add clarification to the term "static" in regards to my situation: It's not that there's static on top of the regular audio; like a bad FM signal, where you can still hear the music or talk show. What I mean by static is that the audio one should hear is completely overcome; you don't hear what should be heard at all (as if there's no signal at all on an FM receiver). Not only does the sound come purely as static, but the static will last considerably longer than the original sound (for example: The Microsoft Ding sound is a one-second audio file; but when that sound is played, the static goes on for at least 5 seconds or more). Also, the static doesn't stay at one pitch or "note" (for lack of recollection of a better term), and it isn't a constant one. There will be changes in pitch and short pauses throughout the broadcast.

It's not just applications

The static sounds aren't just coming from applications like Media Player or IE/Chrome, but the Windows System Sounds as well.

Would an external video recording help?

If needed, I can upload a video from an external camera onto YouTube to show the exact behavior. Let me know and I'll get on it.

Isolate the hard drive lines

by mjd420nova In reply to How to fix Static Sound i ...

This might be a cross of data lines inducing in the analog leads. Some drives will have a distinct pattern of signals. Accessing the drive while listening to audio?Or content with audio. Some CD/DVD drives will induce cross talk when analog outputs are used. Playing content from a jump drive (USB) would be clean as it would be drive access free. Monitor the drive activity light too.

That may be the cause, considering how many drives there are in the computer. There are currently two CD/DVD drives; one connected via SATA, and the other IDE. Then there's the one HDD, also connected via SATA. I'll look into them and see what I find.

I removed the IDE CD/DVD drive, and the WiFi card, but there's been no improvement.
